the most common is dune sand. it is nothing but rocks that has been worn down from the sierras and deposited along the beaches. the wind blew that dune sand over most of the city. it is this mustard color. on the avenues, it is very thick. it can be up to 400 feet thick. as you moved south across slope boulevard, that is the tolar foundation. it was named after the first to score every in -- after the first discovery in the cemetery. the man was out there and noticed this material was unique. he started mapping it. he traced it all the way up to slope. the dune sand generally has the consistency of sugar. it is fine grained sand. it is usually loose. it is poorly graded. the colma foundation can be the same stand but it is denser. it may have to play in it. it is much stronger. it is an excellent supporting material. it is up to 10,000 years old on the dunes and. the colma is 40,000 to 60,000 years old. in some areas, it may be as old as 130,000 years. as you move across the city and get to the border, you get to

within this is phil, bay mud, shall mud, and then down sand. re tom hill, at one time second street ended at howard. at that point, there was a large hill. the wealthy people of san francisco lived on top of the hill, and churches were built along howard. then the city fathers in the 1920's let us knock down the hill, let us extend second street, and it finishes at the ballpark now. as you move south along second, that whole area, you get into rock. many of these old warehouse buildings, as you approach rincon hill, are sitting on rock. if you go down to king street, which is the street that fronts the ballpark, if you cross the street from the ballpark and the look on the sidewalk, there is actually a little brass plates that depict the location of the bluff that existed, the transition from the beach to the vertical cliffs that existed at second street. at second and king. all of that was taken down, and they have built warehouses. now at his condominium developments. and portions of mission bay. the first building of mission bay, third and t

>> guest: it has widespread impact and when you look at the oil sands sands general and what it is doing for the u.s. economy fares already 2400 companies and 49 of our states that are impacted and better working toward supporting this resource. in regards to the cornell study and we can debate that for quite a while too as far as some of the cases and claims they are there are and qualifications of that study. the fact that you can say that any project that is going to be created, that is going to be built, that is going to be starting from scratch was not requesting government funding by the way. this is all based on private investment. it is going to be a job killer -- is ridiculous. there is not a basis for it to take away jobs from americans and if that were the case i would question why you have seen thousands of laborers coming out, thousands of union workers coming out to support this project. there is official agreement with the labor unions about their jobs and what is going to be traded so they are behind this project. they have said even if it is half the amount of jobs they

oil or that have carried tar sands oil so the communities that live along the pipeline the proposed pipeline route have their own reasons for being against it but my reason for going to washington getting arrested alongside more than twelve hundred other people is really about my opposition to the tar sands itself and you know i've been very open about that the reason why we got arrested outside the white house is because you know one of the things we're always hearing from the obama white house is that you know they. would like to do more about they're always being stopped by these they aren't republicans and and and you know obama sort of positions himself to the environmental movement as being their ally as being our ally but were it not for all of these obstructionist people in congress the thing about the keystone x.l. pipeline is that because it is a project that comes from canada which is still another country it actually doesn't have to go through congress to approve a process it has to be approved by the state department because it's a foreign project so the state departmen

is a major major artery so that would allow them to to to accelerate their production of the tar sands it's bill mckibben the wonderful environmental writer and co-founder of three fifty dot org described the keystone x.l. pipeline as the world's longest fuse to the world's largest carbon bomb so that is why so many people got so passionate about stopping the keystone x.l. pipeline or the other reasons or just the dangers inherent in the transportation of the oil because sense oil is more corrosive because it has to be mixed with so many different chemicals just to get it through the pipeline so there's been all kinds of spills on either of the pipelines carrying tar sands oil or that had carried tar sands oil so the communities that live along the pipeline the proposed pipeline route have their own reasons for being against it but my reason for going to washington and getting arrested alongside more than twelve hundred other people is really about my opposition to the tar sands itself and you know i've been very open about that the reason why we got arrested outside the white house is

we are the sand hills lovers. we are the aquifer lovers and we are begging you, not asking, we are digging you to deny this pipeline permit. every day we fight in askari elected officials to stand up for us to do the right thing and change the path of this pipeline. is going through the most fragile parts of our state, the sand hills and it is crashing through the aquifer which provides drinking water for not only our state, but for the very food that we eat every day as farmers and ranchers. and so we are begging do not stand for the foreign oil corporation. stand with americans. stand with nebraskans, stand with our families and please come denied this permit. [applause] spec - laura l-u-e-c-b-e i live in a ranch south of nebraska and i know for many people in here home is a place where you go, it is your sanctuary and safe place. it's where you can be yourself, and to have a foreign company come in and try to take that away from you and everything you have you lived for and worked so hard to make it through and

because the tar sands you know they are not just a disaster for the atmosphere they're also a disaster for the land for the water in alberta and the people who are most directly impacted by that are indigenous people who live downstream from the tar sands you know low go back and in ninety nine which. i think energize a lot of people will weaken the people to the. influence of corporate. corporate culture but really the impact of corporate marketing shall we say for like a better word on culture how corporations are holding in shaping culture and and i'm going how we can push back i'm curious if you see your four minutes we have left here and. from that book to the conversation we just had about the x.l. pipeline and and all the stuff we've talked about in between it's seems to me that there's a fairly smooth curious your thoughts on that. you know the book was about the rich the rise of corporate power and corporations emerging as more powerful than governments but also as our as swallowing our public spaces and swallowing our political process privatizing our education and absolutely

the east and west coast sides of canada so right now the tar sands are landlocked and there is no way but this pipeline to get to china this pipeline is so wanted by the oil industry because it opens up the texas gulf coast refineries the largest group of refineries in the united states actually in the world and those international shipping ports that are down there so many industry analysts are actually saying this pipeline is an export pipeline and right now we're seeing about sixty percent of the oil that's refined down in texas is exported actually down to latin america to europe to other parts of the world and so i think to say if we build this pipeline will get the united states actually not based on the fact that's not what's we're seeing right now in our economy and the truth is that the industry and the banks are watching this decision because this decision is going to drive investment the tar sands because it will be the first international shipping port that the tar sands will have access to now let's just compare this really quick because we had hundreds of people protesti

the sky is infinite, the sand is infinite. it's hard to keep your focus because you are constantly using peripheral vision looking all around you. it doesn't matter which way you walk after a while, you are just wandering. and so on the first trip out there, we didn't get to the sea because we just ended up wandering. it happens out there. you have a plan but the landscape becomes beautiful in a way that you weren't expecting and you start disappearing into it. you start forgetting why you are going in one direction. you start thinking, no, i just want to see that shadow over there and spend time there and then i want to see the next shadow and the next. it took 3 trips actually before we got to the sea. and all over at the edges of the dunes and sometimes even out in the middle of the dunes where you get into a deep hole, you will find a broken ceramic ojalla, you will find a sea shell that somebody carried in there, you will pick up the shell going what were you doing out here, why were you walking in this place, were you se

i'm coming to you from a landscape where once you get an eye for things, 3 grains of sand out of place draw your attention, where everything is brought to bear, where everything is hinged to a story, every drop of rain leaving a dimple in the ground. stories are everywhere out in this landscape. when you walk down into the bottom of the narrow canyons made of sandstone and you put your hands on the sand stone faces and the smooth shallow scallops that look like champagne glasses, you can feel the shape of the last flood that came through. every place in the desert is a story. every place is a passage way. it's really hard to walk very far in the desert for me because there are so many stories that start opening up and lead you from place to place and place and soon you start picking up the patterns of wind, of rain. you pick up the patterns of people who were there before you because, out there, things seem to last forever. if you put a footprint down in certain places, that footprint will stay for 5 years, maybe even 10 years for somebody who's got a really good eye where you come wal

i come from the tar sands area. i represent many first nations in canada and i'm here today representing the families who are also living and dying with very rare and aggressive cancers, which we suspect are cost from the tar centered i'm a former chief of my first nation. we live in an area called the delta which is one of the largest freshwater deltas in the world. unfortunately the tar sands are situated in our traditional homeland and we've been observing many issues of the 40 years of open pit mining of the tar sands, and only 3% of the total tar sand deposits have been mind. and we seemed water quality issues, water quantity issues impact animals, to birds, to big game, the fish health. and more critically we are seeing rare and effective cancers in my community today. we have seen environmental injustices, human rights abuses, repeated infringement of our constitutionally protected treaty rights by both canada and third parties like the multinational oil companies that are invested in the tar sands. there's n

until i could see others and i blew the sand away and i could see the rim of a broken pot. once i saw that, my eye was much sharper and i could see the details around me. i could see a small community, a family of maybe 12 had lived here. when i looked up into the cliff, i saw stacks of rock behind a little spall of the cliff that had stuck out and i realized there was a granary up there. i immediately started for it, climbing hand over hand up the cliff base. my breath tasted hot with discovery. i had found a secret. in past travels i had seen many granaries belonging to the anastasi but they had all been broken open by pot hunters or even by the residents themselves. this one had been built so no one would see it, like an attic accessed through a hidden floor. the structure was rectangular, like a cupboard. i touched its face with probing, diagnostic fingers, measuring it my eyes. 3 feet tall, 2 feet wide and 3 feet deep. i got up on my haunches and lightly dusted off the granaries roof which was undamaged. for 3,000 years not a breeze had entered this chamber, not an ink

because it will be the first international shipping port that the tar sands will have access to now let's just compare this really quick because we had hundreds of people protesting in from the white house against this tar sands pipeline weeks ago and the media paid almost no attention to it compare that to the cylinder a scandal and how much attention that's gotten you know is this occupy movement perhaps helping bring down the keystone pipeline protests to the forefront a little bit well i hope it is i mean it's certainly true that there's some really similar concerns being said we actually had some occupy people that came down the street today a lot of people that self identify as environmentalists and are just fed up that we're not seeing more leadership on environmental issues. i want to thank you so much for joining us tonight and i guess the clock is ticking three weeks left to go but if you had to do it if you had to make a guess is it going to happen or what i will say is that on november sixth about five thousand protesters are coming in from d.c. to encircle the white hou

tar sands present, tar sands spill's present significant challenges. in addition to the potential increased spill frequency, and assessment of its physical properties indicate that it will behave differently than conventional crude when spill. recent experience with this bill in kalamazoo, michigan, show that cleaning these skills had a significant new challenges that have not yet been surmounted. 906 e. 6000 counts of tar sands crude into the kalamazoo watershed in july 2010, the environmental protection agency originally set a two-month deadline for completing the thing. 14 months later, it has nested second deadline. the obama administration has speeded sir, i wish going to ask you if you could kind of you to your final sentence. >> certain. of bomb administration has not been assigned straight i would risk these pipelines post. and report on keystone xl without more due diligence puts the communities, water and environmental resources to the united states at unnecessary risk. [applause] >> thank you. ladies and gentlemen, i regret that the time has

the flip of the wheel sands and the related infrastructure has a potential and is currently creating tens of thousands of jobs in both canada and the united states. we've identified in excess of 2400 companies in 49 states in the united states that currently supply goods or services to the oil sands development of the related infrastructure and there

increasing our reliance on demand sands oil would take us in the opposite direction. -- bitimin sands would take as in the opposite direction. >> i am a member of the maryland student climate corrugation and in our corporate in an organic farmer from southern maryland. from a political system, where money buys power, and the people are ignored. a system were a so-called public servant bows to corp., or the long-term well-being of the public trust is ignored in favor of the short-term profits of the already wealthy. it is a flawed system that we cannot fix immediately, but we can take a step in the right direction. you have an opportunity to. disciple and say no to corp. -- to break the cycle and say no to corporations. you can give the country back to the people who love it dearly. say no to corporate greed and yes the public may. say no to the future of the xl pipeline in yes to a true energy independence. say yes to a clean energy future based on renewables build in this country by american labor, create canterbury jobs. it is not conducive to an energy security and independence. br

sands. for those who do not know it, tarzan's is a high carbon type of fuel that is stripped mind from underneath canada's royal forests, which is one of our last untouched ecosystems in the planet. for tarzans to be extracted, they destroy the land. it takes so much energy to extract tar sands that it has a carbon footprint of about three times that of conventional oil. tar sand extraction's use about four hundred million gallons of water per day from a river, and most of it ends up as toxic waste. it is contaminated with carcinogens such as cyanide. so the indigenous populations in other communities living downstream from these talks the ponds have high rates of rare cancers, lupus, renal failure, and hyperthyroidism. and wells fargo has refused to pull out of the tar sands. the next example is union bank, which is owned by bank of tokyo mitsubishi. a few years ago, they and other banks provided almost $1 billion to build a coal-fired power plant in south africa.

this is from arab motor tv, the sand race in the uae.e a slalom race, these guys are flying up a sand dune and some modified suv here, look at this thing, man, that's blown out. these guys are ripping and roaring through the sand. getting through the flags. but watch what happens. guys -- >> whoa. >> obviously takes a wrong turn. messes something up. but he's on a hill. >> he's going all the way down. >> he's coming all the way down, flipping over the dunes. more than a dozen times this guy rolls his vehicle down the hill. flips over and over and over to the bottom of the sand dune. of course, everybody is coming to his rescue. they get the guy out somehow he finds somehow he's fine. driver wasn't injured. tell us why he's fine. because that thing over the top is called a roll cage. that's what it's designed for. >> do you see how the roll cage is flattened? >> yeah. hmm. >> that's how he survived, because that was there. >> it's not a very good roll cage if it's just -- blll. >> i'm just crushed that the car is so mangled, really, bumme

it's a very heavy, very call it tar sands area where the oil comes from.uld also free up and have a distribution system to go down to the gulf refineries. >> paul: what about the political opposition, not the national environmentalal opposition, but the states that they across through, the pipelines across territory. >> and the governor of nebraska called a session of the legislature there to-- to consider moving it somewhat because it crosses an aquifer. >> paul: he's not against the pipeline per se. >> no, he's talking about moving, moving the pipeline. there's a larger question here, which is the international dimension, because the opponents of it are saying this is an environmental catastrophe and the tar sands are very carbon intensive, and from nasa says if we approve this pipeline it's game over for the climate. >> paul: the climate change activist. >> exactly, what trans canada is going to do if this pipeline isn't approved they will he move it through canada. the company is called trans canada might put it on railroads and ship it to british colu

that is probably sitting on that sand or rock and that is about a quarter cent. so it is ideal. the ground is going like this, the building does not feel it. you feel it, but the building, it is not doing damage to the structure. >> the building next to it, let's say it is wood frame. what are thoseeperiods? >> there are less than a second. the beauty of a wood frame building, it is probably the most forgiving construction. it squeaks, the plaster will crack, and if you don't have the soft story to deal with, you just have your cup of coffee and the one with your life. >> i guess this is turtle bill. >> grandview, turtle hill, san the mountain, -- sand mound, depending on how long you have been living there. >> this is northwest, of golden gate park. the nearest background, sunset and the richmond district? >> way out to the end, that is for smiley, the veterans hospital. this is for smiley. rock, rock, rock, rock, rock. here is hunters point. that rock is called serpent tonight. -- serpentinite. along this zone, there is another rock type, volcanic rock. it is serpentinite. it
