up next on a second look, one of the bay area's most beautiful locations. the point ray's national seashore. and the battle over an oyster operation that's been there for decades. recovering from a wildfire there in the 1990s. controlling the population of elk and deer and surviving a shark attack on the island of

tamales bay. hello everyone i'm frank somerville. welcome to second look. the drake's the got good news today. an injunction was announced, that injunction will remain in place until mid-may. under one owner then another the oyster company has been operating for decades. a federal lease negotiated with the previous owners expired last year. last november as they were deciding to extend the lease, ken salazar visited the drake's bay oyster company. mike mibach was there. >> reporter: drake, clear, cold water and thousands of oysters

oysters. >> there's no chemical used any where. >> well show you the chucking and impacting room. >> reporter: today he hosted the interior of ken salazar. >> i decided to come here today because of the impending issue. >> reporter: that issue on whether or not to extend the company's lease. if he loses his farm, a lot of people are losing a lot more. >> i'm hoping before november 30th. the secretary of interior is going to tell these people that they're not going to lose their job. >> this is a wilderness area. rowe was asking salazar to abide by the lease agreement with the national park service. >> main problem now is you're

changing the nature of this pristine area. with noise, with structures. >> it has major implications and that's why i'm spending the amount of time understanding all the dimensions of the decision before me. >> reporter: decision time in brake's bay. both will know by next week. in 18969 that same area saw a massive fire. we visited to see how the people and bay were recovering. >> reporter: an eerie orange glow filled if sky over emberness. from afar the fire was awesome. up close it was fear and destructive.

45 families lost their homes and 12,000 acres of national seashore burned. >> reporter: amazingly today most of the pristine park is as beautiful as ever. gorgeous vistas and valley, wild flowers still blooming and birds along the west bay. the fire burned just about 15% of the national seashore and that area blackened and dead bishop pines, mansanita and live oaks are found in the area. one year later there's a floor, part of one wall and a spectacular view of drake's bay. >> this is one of the world's great sights, there's no doubt. >> reporter: he and his wife mary anne escaped the flames

but could not escape the life the fire storm started in the late morning on october 3rd. teenagers started an illegal campfire and did not put it. when we arrived at the fire lain 65-mile an hour winds were pushing them through. where they engulfed everything in it path. the fire started like an angry thunderstorms. the humidity was near zero and the firefighters could not stop it. we watched as two more homes went up in flames. this is what's left of that home today.

a slab of concrete and view of tamales bay. several people chose to move, others chose to go through the long and sometimes tedious process of obtaining building permits and negotiations with the company. >> many people are in the process of rebuilding stores it's a much different story. here for the most part nature is rebuilding itself. >> there's a number of baby bishop pines that are now starting to come into this burned out area. the more you look the more you can see. >> reporter: you can find them deep inside the -- throughout the burned area there's a carpet of green.

grasses, shrubs, flowers and tiny trees. >> it's a tremendous success story. it really is. and it's all a natural process that's taking place. you know we did not go through and reseed any areas, everything that's come back it's come back on its open. in most cases the fire rangers have only spotted a few beaver. deer and other large animals are making their way back into the wild area. researchers are monitor. >> in her story, the that 1995 fire appears to have killed at least 98% of those mountain beavers. 10 years later there were some sign that is the population had recovered by wildlife experts

say it could take 20 years to reach the populations before that fire. still to come here on a second look. the high flying effort to control the tullio population in the point rays.

tonight we're taking a second look at the point ray's national seashore. one of the challenges of managing that area is protecting all the wildlife and their habitat. sometimes that means making sure the population doesn't grow so large that it threatens to overwell -pl -- overwhelm the food and land that support it. >> life has been pretty good according to park rangers, maybe too good. rangers in wildlife scientists say the herd is growing too fast. it's increased almost 40% in

the last two years to 165 head. and park officials are afraid the preserve won't be able to handle any more elk without damaging the habitat and all of the plants here. so they are rounding up 30 cows using helicopters and giving them birth control injections. a team of rangers and scientists works on a cow for about 10 minutes. it's the first of its kind experience. the cow gets injections of vitamins and antibiotics in case the captivity and struggle hurts the animal. >> one, two, three. >> beautiful. >> they are in such good health national park officials say because the last two winters have been wet and a lot of food has been growing here. >> what we're really tried to do is reduce the population now because we are predicting down the road we will have a dry

winter and we will not get the population. thus we would not be able to sustain the population and there would be a die off. >> reporter: the only natural predators to the elk are mountain lions. but the mountain lions are so outif you remembered they've had no effect on the mountain lion population. they must let two men named mutters jump out and bring the cow down. once they get the cow town and their net back they leave the work o the scientists. and they're not done yesterday. next year in december i'm going to have to borrow the -- rangers were rounding up

some of the nonnative deer at point rays and killing them. paul chambers brought us this report in 2008 on that controversial program. today between eight and 10 nonnative deer were killed. the plan call for deers to threatened and paralyzed. >> the nay deer which is being suppressed by its population. rangers at point rays are removing nonnative deer named fallon access. in the condor recovery program. >> it's inhumane, it's an inhumane slaughter. there's nothing nice. this video show it is nonnative

deer. since june 460 of the 1,000 living in the area have been slaughtered but this is just the beginning. >> to wipe out hundreds and hundreds of deer simply because they were not here when the park was created long ago to me is absolutely an atrocious way of looking at things. a handful have undergone a surgical procedure which costs five grand per deer. >> that involves removing the ovaries from the deer so they don't reproduce. >> a man talks about surviving a bear attack. plus are there some

artifacts. where you can find them in the bay area.

we're focused on the point rays national seashore. that area was once covered by dairy farms but as the population grew and the dairy industry became more competitive. those farms began to disappear. nearly 50 years ago, efforts began to absorb some of them into the national seashore property. in 2000, bob mackenzie told us the story. >> reporter: it was a few years ago that a farmer wanted to sell his property to the conservation project.

now that is happening. the land was all wetlands until the 1940s when it was dammed and dike for dairy farming. park officials say the dikes could be removed and the area restored to wetland habitat. >> the creeks have both steel head trout andc ohote salmon. for our sake it's a very important and critical piece of the effort. >> reporter: caltrans provided $4.1 million for the acquisition. and congress added another 1- 1/2 million in federal funds. jacamini family members were out of town but the deal allows them to run the family dairy operation on the land for another few years while the park service hold publy hearings on how the land should be use -- hold public hearings

on how the land should be used. so after years of acquisition meetings, this land now belongs to you, me and the state. tamales point just north of point rays is a known shark breeding ground but with just six known shark attack here's in the past 36 years, collin tinley and his two friends featured that diving for abalone would be worth the risk it wasn't. about 20 feet down. >> i was heading toward the bottom when i saw the shark swimming parallel to me. he turned toward me a head on

situation and then came toward me. >> reporter: it was a great white shark like these. tinley tried to block the bite with his arm but the too big. >> i remember seeing the mouth come at me. it was at least from my abdomen to my shoulder. >> reporter: that's the size of the round. one big bite stretching from tinley's collar bone to his stomach including cuts on his forearm. tinley's surgeon found evidence of the bite on tinley's shoulder. >> there's some searuated -- after the bite and a bit of tugging the shark let go. >> i just swam with my right arm. >> swam to his friends in an

inflatable boat. perhaps the shark didn't like the taste of his wet suit but more likely -- >> that's how they hunt. they grab a seal, they cut him up and spit him up so they don't have to fight with him and risk getting themselves injured then they come back after the seal is dead, weak or dead then they devour it. so divers are often pulled out of the water before the shark comes back. >> tinley called for an air rescue helicopter. tinley is an emergency room nurse in sacramento. he says his diving experience and emergency room experience helped him stay calm. tinley's recovery is so smoothly he hopes to get back

to work in a week. and yes he says he will dive again but not at tamales point. when we come back, exploring the mysterious stone formations at tamales bay. who put them there and why. you can't move the tv there. yuh-huh. we have a wireless receiver. listen. back in my day, there was no u-verse wireless receiver that let you move the tv away from the tv outlet. we can move it to the kitchen, the patio, the closet and almost anywhere. why would you want a tv in the closet?

per happens you've been out hiking at point ray and come up on a large standing stone and wondered, who put this here and why did they do it. if you have wondered that you wouldn't be the first one to have done so. john fowler pondered those same questions back in 1998. >> reporter: scattered across the bay area's back country, mysterious rock walls and mountain stone monuments. some may be 1,000 yearsology. the question is, who built them. they are easy to miss but not

so easy to explain. from the sea across this spit of land, the wall disappears a half mile away in the brush near tamales bay. countless hikers have strolled by and have not noticed the stones. is it possible ancient explorers landed here and left behind this 20-foot mega lift a remnant of some kind of signaling or marker. >> there's a permanent rock. that thing could be easily observed. >> i feel very much so it's prehistoric. some of these walls seem to have very ordinary explanations. >> though it looks very much like it's a wall put in by some early maybe dairy farmers or cattle grazers. >> the amount of like and

growth on exposed rock helps fix the age of this rock. >> guess. >> 100, 150 years is probably a reasonable guess. not a real mystery wall not like some of the ones that wander across randomly on the hillside. >> there are plenty of those such as this one. carbon dating on this tree stump indicate these stones may have been in place before the first europeans arrived. the indians built mostly with reeds and wood and that walls would be culturally foreign to them. some short walls possibly hunting blinds are dated more than 1,000 years old. naturalists give tours about these walls. >> speculate about these former civilizations that someone may have visited these shores from china. >> basks, sheep herders and

stuff. martians, lumerians. land grants. walking private ranch land with swanson. it's hard not to get caught up in this mystery. >> if you see this thing, it's collapsed a bit. but you can see it's a middle shape. >> it may have been built 200 years ago or earlier no one knows. this circle of stone feels old. >> it could have been a watchtower or hunting if blind. >> who's went to all this enormous work to put these things together? >> naturalists say a massive construction project like this could only have been done during or after
