most reliable voters here, evangelical christians and tea party enthusiasts. the campaign sent this flier to voters with their voter propensity score that looks like a government doult, but isn't. the point, to shame those to caucus for cruz and bring friends listed. >> i've never heard of anything like this. it is to dishonest. >> reporter: trump attended church this morning. for the first time, said he would appoint supreme court justices to overturn gay marriage. a big issue for iowa's social quemp conserve conservatives. >> i disagree with the supreme court. it should be a state's rights issues. >> reporter: trump's front-runner stat us and rule-breaking ways allowed him to skip the final televised debate and attract rick santorum and mike huckabee. >> i'm endorsing myself. the first thing out of my mouth that night are donald trump and i are competitors but colleagues

>> reporter: santorum told us trump. >> i think i was pretty clear that night when i stood to the side of the podium and said, i don't want to stand behind a trump sign because i'm supporting another candidate tore president. and i intend to run a vigorous campaign. zoo. i'm nancy cordes. >> it's an honor -- >> reporter: there is no poll that can tell you -- >> we're calling with the hillary clinton campaign. >> reporter: -- which democrat has the better ground game. >> i'm glad to hear you'll be supporting the governor. >> reporter: in a race as close as this one there is nothing more important. the candidates made their closing arguments today. >> and there's a big difference between what i believe will work and what the republicans are selling. >> reporter: clinton has done more than 100 events in iowa. sanders isn't far behind. >> starts working for all of us, not just the 1%.

two separated by just three points. that means former maryland governor, martin o'malley, who is polling at 3%, could become a kingmaker. >> i would love to be the second choice of the sanders or the clinton people. >> reporter: caucuses allow supporters to horse trade with one another. come tomorrow night, both the clinton and sanders camps will try to convince o'malley voters to work with him. the longest his people hold out, the more leverage they have. >> my message to the o'malley supporters across the state is this, hold strong at your caucus. >> reporter: his troops know their marching orders. >> i'm holding strong on caucus night. >> the hold strong message is our conviction. >> reporter: nancy is a o'malley volunteer and saw the strategy work before when she was a precinct captain for president obama. >> i remember in '08, went to talk to the biden group, and that only got them to come over.

up being two of my top volunteers for obama. so, it's pliable. >> reporter: and so o'malley's final tally tomorrow night could outstrip his poll numbers if the other two swing supporters his way in an attempt to depress each other's delegate count. it is very complicated, jeff. makes things very unpredictable which is why even at this hour here at sanders' headquarters, they are still sending volunteers out into the streets to knock on doors and drum up support. >> thank you, nancy cordes, major garrett and our entire team in iowa. peace talks aimed at ending the war in syria are getting under way in geneva, switzerland. allen pizzey reports as syrians continue to die inside their country and trying to escape. we warn, the footage is graphic. >> reporter: this tushish beach is a long way and no distance at all from the would-be peace talks in geneva. even as the participants argued

get down to business, drowned children and their families fleeing the conflict washed up on shore. by some counts, 35 times more people have tried to make the perilous crossing to greece, at least 250 are believed to have drowned this month alone. this is the type of horror that makes them take the risk. dozens were killed in damascus when a car bomb went off. two suicide bombers then struck rescuers, adding to the carnage. >> syria today is an unfolding humanitarian catastrophe. >> reporter: in a video message secretary of state john kerry called on participants in the peace talks to seize the opportunity to bring an end to the conflict. the talks are supposed to begin in some form on monday. >> this conflict could easily engulf the region. if left to spiral completely out of control. that is what the negotiations in

>> reporter: but so far, the parties to the talks are refusing to even speak directly to each other. in spite of the messages from adaa damascus suburb. the "cbs overnight news" will be right back. almost sixty million americans are affected by mental illness. together we can help them with three simple words. my name is chris noth and i will listen.

across the country are getting in on the action by volunteering in their communities. chris young: action teams of high school students are joining volunteers of america and major league baseball players to help train and inspire the next generation of volunteers. carlos pea: it's easy to start an action team at your school so you, too, can get in on the action.

if you were a hippie in the '60s, you need to know. it's the dawning of the age of aquarius. yeah, and something else that's cool. what? osteoporosis is preventable. all: osteo's preventable? right on! if you dig your bones, protect them. all: cbs cares! two virginia tech students were arrested this weekend in connection with the death of a 13-year-old girl.

police believe she was murdered. >> reporter: police say 13-year-old nicole lovell was abducted by david eisenhauer and they say keepers helped him. today keepers was arrested. blacksburg police detective -- >> we have determined they were acquainted prior to her disappearance. >> reporter: saturday authorities charged eisenhauer with murder. they found lovell's remains about 100 miles from her home. her family reported her missing on wednesday and say her dresser was pushed up against her bedroom door. a missing child poster noted she required medication daily for her liver. friday, her father posted this message to facebook. >> nicole, honey, if you see this, if you're out there, you can come to me. i'm not mad at you.

just come home. >> reporter: nicole's facebook page shows she was a member of at least one teen dating group, but it's unclear whether she met eisenhauer on line. last march the track and field state champion was honored as athlete of the week by a local news station. >> i will personally not stop until i reach my peak performance. >> reporter: investigators spent four days searching for lovell. state police continue to search for evidence on the virginia tech campus. virginia tech released a statement extending its support to lovell's family and friends. police have not released a motive or cause of death. the oobs isautopsy is scheduled for tomorrow. >> thank you very much. the super bowl teams arrived in the bay area today, one week ahead of the big game. the denver broncos landed about an hour before the carolina panthers. behind the scenes, teams of federal and local law enforcement officials are fine-tuning their security plans for the super bowl. john blackstone has an inside

>> reporter: celebrating the biggest week in football, san francisco is expecting 1 million visitors a day. six blocks downtown has been turned into super bowl city. it's a place where football fans big and small can play interactive games and pose for photos. but first, they will have to line up to go through metal detectors. san francisco's police chief. >> there will be officers in plain clothes, on high ground, but a lot of it will be unseen to the regular person that's just going to come and have a great time in san francisco. >> reporter: law enforcement agencies have been planning for this for two years. coast guard canine units are on hand to screen the crowd for explosives. the fbi brought bomb-detecting robots just in case. dozens of federal, state and local agencies have set up a joint operations center.

>> really what this facility is for is to collect information, thread information, intelligence, analyze it and get it out to the people that need to know. >> reporter: geography is making security planning more difficult. while many events are taking place in san francisco, levi stadium is 45 miles away in santa clara. that's where 70,000 people will gather for the game next sunday. while fbi officials say there's no known credible threat of a terror attack, an individual working alone can present a clear danger. >> it's all about identifying the lone wolf before he or she acts. hard to find. absolutely, no doubt about that. i think we saw that in san bernardino. >> reporter: part of the security plan depends on all these fans being watchful as well. at every opportunity, jeff, san francisco's police chief repeats the phrase, if you see something, say something. >> john blackstone, thank you. el nino continues to soak

highway 101 in ventura county was flooded today. conditions at the farmer's open in la jolla were very bad. some parts of the state were expecting up to 3 inches of rain. multiple delays at the golf tournament. that is helpful in battling drought, the rain, but unhelpful in the fight against another insidious problem -- cliff erosion. here's carter evans. >> reporter: relentless el nino-powered waves are taking a human toll. but this crumbling hillside south of san francisco is giving scientists a gold mine of information. the nature conserve ancy has asked drone operators to capture a perspective rarely seen. >> drones provide this really great perspective you can't get safely any other way. we're below the clouds, right near the sea level. and shooting back at the shore. >> reporter: the drones buzzing above this cliff aren't just taking dramatic pictures. they're gathering data to help

california coastline. what have you seen along the coastline so far? >> i've seen a lot of destruction. >> reporter: this week george flew his drone in a grid above endangered buildings in pacifica, like this apartment building now teeting ingteetering on the edge. >> the high tides are going and hopefully in the future we'll be able to predict things like what happened here at the apartment complex. >> reporter: it's a big job. there's 1270 miles of shoreline along california. and scientists have identified several thousand homes that may be in jeopardy during this el nino winter. the work you do here today might here tomorrow. that's the point. >> reporter: it could eventually help those who never intended to live on the edge. pacifica. all three inmates who escaped a southern california

the last two fugitives who face charges including murder and torture returned to jail overnight. they were captured in san francisco yesterday. a third inmate surrendered friday. this time the men are being kept in separate cells. still ahead, accusations of racial intolerance at an elite boston high school. and an extremely rare albatross sighting.

a boston high school known for being at the center of diversity and progressive politics is now at the center of a controversy after students began a social media campaign alleging racial incidents on campus campus. kenneth craig reports. >> we want to blow up every single social media. >> reporter: when meggie noel and kylie webster-cazeau made this youtube video. the students claim underlying racial tensions in the hallways and online ramped up when ferguson police officer darren wilson was not indicted in the shooting death of michael brown. >> it made students of color really uncomfortable that students who they sit next to in

see in the hallway, whose locker is next to them said these things and thought these things. >> reporter: among their claims they say school officials did not reprimand students who openly used racial slurs at school. using the #blackatbls, they're now encouraging other students to join the conversation. that video has now gone viral and the discussion is expanding. boston mayor marty walsh is supporting them. >> the experiences that our kids have in our schools shouldn't be racism. >> reporter: the district is now investigating. boston latin is the oldest public school in the country, considered a top feeder school for the ivy league with a long list of prestigious graduates. 22 years ago, roughly 23% of the student body was black. today african-american students make up less than 9%. >> whatever happens, we're definitely going to be holding the administration accountable to make sure these things don't persist in the future. >> reporter: the school's head master has laid out a six-point plan to address the issue.

off with students also joining the discussion from other boston schools. >> kenneth craig, thank you very much. up next here, what soda

flat sales. soda sales have fizzled about 14% in the past decade but cola companies are making moves to turn things around with pepsi opening its first restaurant this week. with jill schlesinger, in part, they're selling this by selling smaller cans? >> yes. it's working. consider it portion control. a lot of americans are trying to cut down on their sugar and they're actually willing to pay more for a smaller size.

months of last year, small can sales were up by 15% since 2011 large sales are down by 5%. so, they're actually stemming the tide of sliding sales with these smaller containers. >> marketing is always such a massive part of this. coke is spending $4 billion in 2016. >> and it's a retro campaign. called taste the feeling. it's aimed at both millenials and boomers. we don't know whether it's going to work, but they're throwing a lot of money at it. pepsi going old school. they're sponsoring the super bowl halftime show again. this seems to work. the combination of the nfl and pepsi. stores say they actually drive traffic. pepsi's marketing machine will drive traffic into the stores. pepsi's happy because they sell more product. they're also trying these new ideas like this restaurant. >> yeah, let's talk about this, this pepsi restaurant. >> it's not called the pepsi restaurant. it's called the kola, with a

the kola nut, the basis for these sodas. when you look at the ingredients, it goes far afield. you can get vodka infused with bitters. you can get your meat drillsed with truffle oil. it's a far cry from pepsi, chips and dips, but maybe it will work. we'll have to wait and see. >> jill, thanks very much. a golf stroke for the ages today. golfer with a hole-in-one on a par 4. it is the first time that has happened in the history of the lpga. 3 under par is anal ba tros or a double eagle. she was pretty excited about, it as you can see. still ahead, extremely tough sledding, even for these athletes. chest pain, like there's a ton of weight on your chest. severe shortness of breath. unexplained nausea. cold sweats. there's an unusual tiredness and fatigue. there's unfamiliar dizziness or light-headedness. unusual pain in your back, neck, jaw, one or both arms, even your upper stomach,

don't make excuses. make the call to 9-1-1 immediately. learn more at womenshealth.gov/heartattack. when the twins were about 10 days old, the doctors told us they were going to need blood transfusions. we're so proud of who they've become. as a result of one person, deciding to spend an hour of their life giving blood is just immeasurable, how powerful that one donation could possibly be.

we close tonight in the frozen north with a shred dog race. it's not as long as the iditarod but just as cold and those up for a challenge, just as invigorating.

cheer and a rousing song -- >> go! >> reporter: -- a 32-year-old tradition is under way. the bear breeze is a gruelling 383-mile sled dog marathon. extreme, rugged terrain in the dead of a north minnesota winter. >> you have to be tough. >> you have to trust in your dogs. >> reporter: preparing for the race means months of vigorous training. >> good girl! >> reporter: and no one knows that better than colleen wallin. >> they all have personalities and they're all smarter than all of us put together here. >> reporter: she has competed 15 times. she's turned the race into a family affair. >> it's right in our own backyard. >> reporter: training usually starts in september. her team of dogs runs 100 miles each week. while eating 4,000 calories of meat each day. that meat is expensive. multiplied by a dozen dogs, it's an investment.

willing to spend the time and money expected for the races. this year about 30 mushers participated in the race, which is less than half than a decade ago. for wallin and her family, it goes beyond the trail. it's very spiritual. a great time to get your family outdoors and see the crazy dogs. >> reporter: a relationship rooted in deep tradition. now up to the future generation to stay on course. >> come on, guys. >> reporter: cbs news. that is "the overnight news" for this monday. for some, the news continues. for others, check back with us later for the morning news and "cbs this morning."

jeff glor. this is the "cbs overnight news". >> welcome to "the overnight news," i'm jeff glor. the first votes will be cast white house.

in fire houses, church basements, homes and more to caucus. tightening. for the democrats hillary clinton has a three-point lead over bernie sanders. 45% to 42%. for the republicans in the latest poll, donald trump is on top with 28%. is he followed by ted cruz with 23%. and marco rubio with 15%. john dickerson discussed the race with both trump and rubio for "face the nation". >> in iowa, your campaign is based on the idea you're a winner. does that mean you have to win iowa? >> i don't have to win it. right now, you and i are sitting in new hampshire. as you know, i have a substantial lead in new hampshire but i think it would be really good to win iowa. i'd like to win iowa. i'm doing really well with evangelicals in iowa but i'm also doing tremendously well with evangelicals. i'm doing great with the tea party. i'm doing great with all groups. i now have a fairly substantial lead in iowa. i think we have a good chance of winning iowa. >> weeks ago it was tighter in iowa.

why do you think that is? >> i think ted cruz has been severely affected by the goldman sachs loans, which he didn't disclose and was on his personal financial form and his citibank financial forms he didn't disclose. >> couldn't it be a mistake? >> it's two loans, give me a break. he's supposed to be robin hood. don't forget, he said he sold his assets. much more important is the whole fact he was born in canada. and he was a citizen of canada until 15 months ago. lot of constitutional lawyers are coming out. laurence tribe is middle ground, saying it's untested. many top constitutional lawyers are coming out saying ted cruz can't be president because of the fact he was born in canada. i think that has a huge effect. >> at your rallies you say things, and i talk to people who attend your ral lis and they like you're uncompromising. i also talk to washington insiders, some lawmakers, who

about you thinking he's going to washington. which is right? >> i think everyone's right. honestly, i think they're both right. i'm tough to make a deal with. but i'm a dealmaker. when i see ted cruz standing in the senate and nobody else is with him, he's standing all by himself, you have all of these other politicians, senators and congressmen generally and he's i can understand how a radio show host could say, oh, isn't that wonderful? not going to get anything done. have you to get things done. ted doesn't have an endorsement from one united states senator. >> he would say that's great because you have said such terrible thinss about them in washington. >> they're not bad people. a lot of are very good people. some are people that won't get it done. the recent budget that was passeds is a horror show. it is should have never been passed, et cetera, et cetera. when ted doesn't have one senator, like mike lee who's a

why isn't he getting endorsements? i get the endorsements from sarah palin, jerry falwell jr. i have incredible -- even sheriff joe endorsed me. >> those aren't senators. those are -- >> no, but still very important people. as an example, sheriff joe, arizona, toughest guy. he endorsed trump. you know what that means? i'm toughest on the border. >> why do you think -- have you a lot of working people at your rallies. you have more than any other candidate, you live a life most distant from them. why do they support you? >> because i'm a job producer. i've produced tens of thousands of jobs over my lifetime. right now i'm producing thousands of jobs. that includes health care, education for families. you know, et cetera, et cetera. and i grew up -- my father was a builder in brooklyn and queens. i grew up with people working on houses and whatever. i relate to them. i love those people. those are my people. i love them. i really do.

i love the firemen. for whatever reason, it is strange -- >> even to get to your job, you don't ride three buses and have a second job and all that. >> no, i have the ultimate bus. it's called a 727. now it's a 757, actually, when you think of it. one of the reasons that i'll win and i think none of the other guys will win is because i'm going to get states that they'll never get. i have a good chance of getting new york, as an example. i have a good chance of getting virginia. i'll get pennsylvania. i'll get ohio. i'll get michigan. i'll get florida my numbers just came down. i'm at 48. the sitting senator is at 11 or 12, and a former governor is in the 8s. >> you may be getting a lot of the last-minute votes going your way. how does it feel? >> well, we've always felt great about our campaign here. we continue to feel that it's growing in support. we'll see what it leads to on monday night. ted cruz is clearly the front-runner going into the night. he has 10,000 volunteers on the ground. he's spent an exother tant

and has gotten every endorsement he wanted. we know it's a tough hill to climb but we feel good about our campaign and very positive about hampshire. we'll be leaving aas soon as the caucus is over and we'll be in new hampshire ready to work. >> sounds like you're setting there. he's calling you the republican obama. what do you think of that? >> other than the fact that i -- it's kind of bizarre. polls. he has a vast organization here and has spent a lot of money. his campaign has bragged repeatedly about how well they'll do here. it's strange that at the last moment they've pivoted all their attacks against me. they took a video of an interview i did in 2007 in florida and clipped it so it makes it sound like i support cap and trade. this has already been lampooned and mocked for years because others have tried to do the same thing.

i don't understand why. he's got such a strong organization here in iowa but it's all fine. we feel good about it. >> make it means you must be doing something right? >> we've taken more than anybody else in attacks. jeb bush's super pac has spent close to $30 million on television which is more than every other attack on every candidate combined. you add ted cruz's attacks. when people don't attack a candidate that has no chance to win. we feel good about it and feel even better it's having no impact and we're continuing to message. we're going to close strong here with our message. we like where that leads. we look forward to moving on to new hampshire and south after that. >> let me ask you about those pac. spent a lot of money attacking you. steven hayes of the "the weekly standard" said the lasting legacy of those attacks may be to make donald trump the nominee. what do you think of that?

believe will be the nominee. that said, yeah, jeb has the right to spend his money any way he wants. i think people have noticed that it's close to $30 million of attack ads against me. i knew that when i got into this race that the establishment, many people in the republican establishment didn't want me to run. they thought i needed to wait my turn or wait in line. but i just felt that after seven years of barack obama, this was no time for patience. it was a time for action. and so i ran and i knew that i would face some of this. this is big dollar checks that were written into that super pac. i'm sure some of the people that wrote those checks are disappointed and others, perhaps, this is what they intended all along. in the end, this election is in god's hands, as everything is. we'll do our very best and we're confident about where that leads.

nancy cordes in des moines explains it all. >> reporter: so, here is your caucus 101. 7:00 p.m. monday night in more than 1600 precincts across the state, people will gather in church basements, in school gymnasiums and even in private homes. just like a primary, whoever gets the most votes wins, but it's how they get there that's a little different. >> wherever i go in iowa, you know the crowds are always packed. >> god bless the great state of iowa. >> reporter: no matter how many supporters show up at their rallies -- >> i am thrilled to be here at marian. >> the weather is vermont weather. thank you, iowa. >> reporter: the only crowd count that really matters is on caucus night. >> so, there are 20 precincts in west des moines. >> reporter: in des moines clinton supporter, julie, is schooling her fellow caucus captains. >> our ultimate goal, as it says on a number of different papers s to get more people for hillary. >> hi. how are you? >> reporter: they need training because caucuses are a little confusing.

>> i mean, why not just vote? >> it means a meaning of chieftains. >> reporter: the good wife tried to explain in a recent episode. >> literally a gathering of neighbors trying to convince each other to support their candidate. >> reporter: even the sanders campaign attempted to sum it up in this facebook video. >> prove them wrong and caucus for bernie. >> it's going to be [ bleep ] awesome! >> reporter: here are the basics. for republicans, it's simple. voters express their preference and the process ends there. for democrats, though, it's more complicated. iowans separate into camping according to the candidate they support. any candidate who doesn't hit 15% in that precinct is eliminated and that candidate's supporters can then choose to back someone else. >> approach them with a show of respect for their candidate and for them. >> reporter: a unique process where neighbors convince neighbors to switch sides.

sanders at all? >> reporter: the more precincts you win, the more delegates you get. that plays into the strategy. for the sanders campaign, for example, they have lined up volunteer drivers to take college students from their college towns to their hometowns to caucus. that way his large base of youth support will be more spread out across the state. >> with more on the race in iowa, here's major garrett. >> we are going to make america great again. >> we need a political revolution. >> reporter: welcome to the presidential campaign that breaks all the rules. >> let me say, i'm a maniac. >> reporter: there's the, you can't say that rule. donald trump breaks it almost daily. >> isis is making a tremendous amount of money. i would bomb the [ bleep ] out of them. >> reporter: no oval office vacancy for socialists. >> bernie! >> reporter: tell bernie sanders.

certainly can and will be. >> reporter: and armada of campaign cash and famous last name can never help. >> incomes went up for everybody. >> reporter: then the all men rule. clinton has the best chance in history to break a 240-year-old glass ceiling. presidential politics, governors and former governors are supposed to have notbuilt-in advantages. >> i had to make these decisions after 9/11. >> reporter: it worked for george w. bush, bill clinton, ronald reagan and jimmy carter, but not bobby jindal, and scott walker. they've all dropped out. while democrat martin o'malley struggles in single digits. and most bizarre of all -- >> donald trump has chosen not to attend this evening's presidential debate. >> reporter: attendance at a prime time televised debate

good thing, a bad thing? will i get more votes? will i get less votes? nobody knows. who the hell knows. >> if i'm elected president. >> reporter: what go governing experience, politicians with the least, ted cruz, marco rubio, trump and even ben carson, have turned that question upside down. the only rule that seems to apply is the old rules no longer apply. >> hi. how are you? >> reporter: new ones are being written daily and the and down the road are anyone's guess. by one count there have been 60,000 political ads run in iowa alone. one series of tv commercials is standing out. here's dean reynolds. >> this election is about the essence of america. about all of us who feel out of place in our own country. >> i have spent my life fighting for children, families and our country. >> there are those who say we cannot defeat a corrupt political system and fix a rigged economy. >> reporter: if you're lucky

most reliable voters here, evangelical christians and tea party enthusiasts. the campaign sent this flier to voters with their voter propensity score that looks like a government doult, but isn't. the point, to shame those to caucus for cruz and bring friends listed. >> i've never heard of anything like this. it is to dishonest. >> reporter: trump attended church this morning. for the first time, said he would appoint supreme court justices to overturn gay marriage. a big issue for iowa's social quemp conserve conservatives. >> i disagree with the supreme court. it should be a state's rights issues. >> reporter: trump's front-runner stat us and rule-breaking ways allowed him to skip the final televised debate and attract rick santorum and mike huckabee. >> i'm endorsing myself. the first thing out of my mouth that night are donald trump and i are competitors but colleagues

volunteers for obama. so, it's pliable. >> reporter: and so o'malley's final tally tomorrow night could outstrip his poll numbers if the other two swing supporters his way in an attempt to depress each other's delegate count. it is very complicated, jeff. makes things very unpredictable which is why even at this hour here at sanders' headquarters, they are still sending volunteers out into the streets to knock on doors and drum up support. >> thank you, nancy cordes, major garrett and our entire team in iowa. peace talks aimed at ending the war in syria are getting under way in geneva, switzerland. allen pizzey reports as syrians continue to die inside their country and trying to escape. we warn, the footage is graphic. >> reporter: this tushish beach is a long way and no distance at all from the would-be peace talks in geneva. even as the participants argued

get down to business, drowned children and their families fleeing the conflict washed up on shore. by some counts, 35 times more people have tried to make the perilous crossing to greece, at least 250 are believed to have drowned this month alone. this is the type of horror that makes them take the risk. dozens were killed in damascus when a car bomb went off. two suicide bombers then struck rescuers, adding to the carnage. >> syria today is an unfolding humanitarian catastrophe. >> reporter: in a video message secretary of state john kerry called on participants in the peace talks to seize the opportunity to bring an end to the conflict. the talks are supposed to begin in some form on monday. >> this conflict could easily engulf the region. if left to spiral completely out of control. that is what the negotiations in

>> really what this facility is for is to collect information, thread information, intelligence, analyze it and get it out to the people that need to know. >> reporter: geography is making security planning more difficult. while many events are taking place in san francisco, levi stadium is 45 miles away in santa clara. that's where 70,000 people will gather for the game next sunday. while fbi officials say there's no known credible threat of a terror attack, an individual working alone can present a clear danger. >> it's all about identifying the lone wolf before he or she acts. hard to find. absolutely, no doubt about that. i think we saw that in san bernardino. >> reporter: part of the security plan depends on all these fans being watchful as well. at every opportunity, jeff, san francisco's police chief repeats the phrase, if you see something, say something. >> john blackstone, thank you. el nino continues to soak

highway 101 in ventura county was flooded today. conditions at the farmer's open in la jolla were very bad. some parts of the state were expecting up to 3 inches of rain. multiple delays at the golf tournament. that is helpful in battling drought, the rain, but unhelpful in the fight against another insidious problem -- cliff erosion. here's carter evans. >> reporter: relentless el nino-powered waves are taking a human toll. but this crumbling hillside south of san francisco is giving scientists a gold mine of information. the nature conserve ancy has asked drone operators to capture a perspective rarely seen. >> drones provide this really great perspective you can't get safely any other way. we're below the clouds, right near the sea level. and shooting back at the shore. >> reporter: the drones buzzing above this cliff aren't just taking dramatic pictures. they're gathering data to help

california coastline. what have you seen along the coastline so far? >> i've seen a lot of destruction. >> reporter: this week george flew his drone in a grid above endangered buildings in pacifica, like this apartment building now teeting ingteetering on the edge. >> the high tides are going and hopefully in the future we'll be able to predict things like what happened here at the apartment complex. >> reporter: it's a big job. there's 1270 miles of shoreline along california. and scientists have identified several thousand homes that may be in jeopardy during this el nino winter. the work you do here today might make it safer for people to live here tomorrow. >> hopefully. that's the point. >> reporter: it could eventually help those who never intended to live on the edge. carter evans, cbs news, pacifica. all three inmates who escaped a southern california

a boston high school known for being at the center of diversity and progressive politics is now at the center of a controversy after students began a social media campaign alleging racial incidents on campus campus. kenneth craig reports. >> we want to blow up every single social media. >> reporter: when meggie noel and kylie webster-cazeau made this youtube video. the students claim underlying racial tensions in the hallways and online ramped up when ferguson police officer darren wilson was not indicted in the shooting death of michael brown. >> it made students of color really uncomfortable that students who they sit next to in

see in the hallway, whose locker is next to them said these things and thought these things. >> reporter: among their claims they say school officials did not reprimand students who openly used racial slurs at school. using the #blackatbls, they're now encouraging other students to join the conversation. that video has now gone viral and the discussion is expanding. boston mayor marty walsh is supporting them. >> the experiences that our kids have in our schools shouldn't be racism. >> reporter: the district is now investigating. boston latin is the oldest public school in the country, considered a top feeder school for the ivy league with a long list of prestigious graduates. 22 years ago, roughly 23% of the student body was black. today african-american students make up less than 9%. >> whatever happens, we're definitely going to be holding the administration accountable to make sure these things don't persist in the future. >> reporter: the school's head master has laid out a six-point plan to address the issue.

off with students also joining the discussion from other boston schools. >> kenneth craig, thank you very much. up next here, what soda

flat sales. soda sales have fizzled about 14% in the past decade but cola companies are making moves to turn things around with pepsi opening its first restaurant this week. with jill schlesinger, in part, they're selling this by selling smaller cans? >> yes. it's working. consider it portion control. a lot of americans are trying to cut down on their sugar and they're actually willing to pay more for a smaller size.

months of last year, small can sales were up by 15% since 2011 large sales are down by 5%. so, they're actually stemming the tide of sliding sales with these smaller containers. >> marketing is always such a massive part of this. coke is spending $4 billion in 2016. >> and it's a retro campaign. called taste the feeling. it's aimed at both millenials and boomers. we don't know whether it's going to work, but they're throwing a lot of money at it. pepsi going old school. they're sponsoring the super bowl halftime show again. this seems to work. pepsi. stores say they actually drive traffic. pepsi's marketing machine will drive traffic into the stores. more product. they're also trying these new ideas like this restaurant. >> yeah, let's talk about this, this pepsi restaurant. >> it's not called the pepsi restaurant. it's called the kola, with a "k," the kola house and

the kola nut, the basis for these sodas. when you look at the ingredients, it goes far afield. you can get vodka infused with bitters. you can get your meat drillsed with truffle oil. it's a far cry from pepsi, chips and dips, but maybe it will work. we'll have to wait and see. >> jill, thanks very much. a golf stroke for the ages today. golfer with a hole-in-one on a par 4. it is the first time that has happened in the history of the lpga. 3 under par is anal ba tros or a double eagle. she was pretty excited about, it as you can see. still ahead, woman: what does it feel like when a woman is having a heart attack? chest pain, like there's a ton of weight on your chest. severe shortness of breath. unexplained nausea. cold sweats. there's an unusual tiredness and fatigue. there's unfamiliar dizziness or light-headedness. unusual pain in your back, neck, jaw, one or both arms, even your upper stomach,

don't make excuses. make the call to 9-1-1 immediately. learn more at womenshealth.gov/heartattack. when the twins were about 10 days old, the doctors told us they were going to need blood transfusions. we're so proud of who they've become. as a result of one person, deciding to spend an hour of their life giving blood is just immeasurable, how powerful that one donation could possibly be.

we close tonight in the frozen north with a shred dog race. it's not as long as the iditarod but just as cold and those up for a challenge, just as invigorating.

cheer and a rousing song -- >> go! >> reporter: -- a 32-year-old tradition is under way. the bear breeze is a gruelling 383-mile sled dog marathon. extreme, rugged terrain in the dead of a north minnesota winter. >> you have to be tough. >> you have to trust in your dogs. >> reporter: preparing for the race means months of vigorous training. >> good girl! >> reporter: and no one knows that better than colleen wallin. >> they all have personalities and they're all smarter than all of us put together here. >> reporter: she has competed 15 times. she's turned the race into a family affair. >> it's right in our own backyard. >> reporter: training usually starts in september. her team of dogs runs 100 miles each week. while eating 4,000 calories of meat each day. that meat is expensive. multiplied by a dozen dogs, it's an investment.

willing to spend the time and money expected for the races. this year about 30 mushers participated in the race, which is less than half than a decade ago. for wallin and her family, it goes beyond the trail. >> it's very moving. it's very spiritual. a great time to get your family outdoors and see the crazy dogs. >> reporter: a relationship rooted in deep tradition. now up to the future generation to stay on course. >> come on, guys. >> reporter: cbs news. that is "the overnight news" for this monday. for some, the news continues. for others, check back with us later for the morning news and "cbs this morning."
