At the time the moment of all sherpas is that we should mourn for everest. Guides are calling for more insurance money and more compensation for the families of those lost.

Texas doctor beckwetters lost an arm, fingers and nose to frostbite. Crockhower was covering the proliferation of guided tours promising a safe trip to the top of the world.

And it kills experienced climbers as well as neofites. Richard wheats runs camp everest. Who takes climbers to 1,700 feet. There were over 300 people there the most ive ever seen. 16 expeditions. Reporter near Company Charges less than 4,000 to visit base camp and does not do the summit. Paying for guides and permits to the top can cost more than 60,000. This is everest. Right. And it doesnt matter what day of any month of the year there the always be storms there and that is part of the allure for many many people. You take the chance. Reporter crackhower on assignment thinks guided climbs should be banned. Theres these weird diseases at the altitude. Your lungs fill with fluid without warning. Your drown in your own juices. Your brain swells and you unconscious. A lot can go wrong. Reporter many sherpa people think are spiritual. They feel if climbers do not respect the mountain the gods will get angry. Reporter juandela made it to 27,000 feet. What he witnessed sounds impossible. Pollution, poisoning the environment at the top of the world. There was a lot of pollution at base camp. How bad is the pollution there . Its very bad. Bottles and tissues and plastic everywhere. Reporter he was so upset he enrolled in the Environmental Studies Program at cal. He showed me pictures. Hundreds of orange colored oxygen bottles littering the landscape 5 miles high. Climbers have no incentive to take their crash back down the mountain. This area is very polluted here.

Why dont you go get some frozen yogurt. I got this. Youre so sweet. You got this, right . I do got this. From the shelf, and to your home. Starting at 99. Tonight on a second look the magic and mystery of Mount Everest. One of the best known tragedies. Eight people died in a blizzard. Brashier and his i max team were on everest. He sat down to talk about what it was like. How many times have you climbed . Four times. 11 expetitions to the mountain and four times to the top. You just happened to be there when is this blizzard hit. You were there with your camera. A lot of things have changed. Last year in may, we had 12 teams on the mountain. Theyre making a movie about which is documented on the book about our climb and thats when we ended up getting involved in the tragedy. We have a picture of the, i believe its your. Yes. You took the pictures. What were look at now is actual video. But we have pictures of the tents you took at night. Yes this is a beautiful shot at night at base camp. Base camp is 17,600 feet. And at night is the ice fall where we went into. So has the blizzard hit . No. So you had no idea. No, but one of the reasons was the climbers were a little overcrowded. Are these the climbers that got in trouble. Thats only 300 feet below the top and that is scott fishers and rob halls team. Both of them died. The climber on the top left is climbing just above what we call the hillary step. The last obstacle. How would you describe so we get a feeling what conditions are like when youre that high on Mount Everest. When youre that high on everest. Youve been 50 to 60 hours without more than three to four hours of sleep. Youre sleep deprived then, youre hipoxic which means your body is oxygen strived. Youre severely dehydrated and malnourishedded. Great combination of things. Seems like something all of us and youve been up there four times to do that. We also have a photo of you with your imax camera. Youre with a colleague here. How much does this camera weigh. The top part weighs 24 pounds. To hold a big camera like that still you need a 70pound tripod and head. It uses 4. 5 pounds of film, 500 feet of film in 90 seconds. So how much film did you have to take to the top of Mount Everest. I took one roll to the very stop. It was two weeks after the blizzard when eight people died that you actually did make it again to the top of Mount Everest. And in your travels when you were trying to help, this is one of the bodies you discovered. Who is this . We dont know who this was. The bodies we found were higher up. But this photo is in our book just to illustrate the fact that with this increased number of people climbing on the mountain theres more accidents and its grim thought but that was just an anonymous body. The truth is thats only half a body right there. Someone had fallen down years before and now their body had come out of the snow. When you found a body. What do you do . Do you leave it in that position or i guess its kind of ceremonial to find a crevase and drop it down if you can. That would be lower down. The state youre in which is the state i was in when we passed our fallen friend scott fisher and ron hall, youre in a tran state. You are barely able to put one foot in front of the other. Youre in no position to remove bodies. And to get to the top you must do this. We used 65 ladder sections this year spanning maybe 15 or 20 crevases like that. Its a lot more dangerous than it looks. Were not crazy. Were most of us are not thrill seekers. Were very cautious people. A number of people have lost their lives crossing that very ice. Yes but not from falling in the crevase. From having this wall fall on you but its very rare for someone to fall of a ladder into a crevase. And you also passed someone you thought was dead. Thats rivers. He dame back to death. His nose is frostbitten. His lips are frostbitten. His eyes are swollen shut. His hands are frozen solid down to the wrist. But the guy is alive and hes telling jokes and hes telling us how thankful he is that were there waiting for him. So it was just wonderful out of all that terrible mess of may 96 that we had this gift of beck weathers. The outcome for him was he lost both hands and had to have his nose restructures. How is he today is how he is today if. He is back at work. They made him a way to grasp from his left hand. Hes a pathologist, he needs his eyes and brains. He can still look through the microscope and make decisions in biopsies. One of the persons you died were you on the phone. No, thankfully we had headed up from from camp two to camp three. After conversations with rob hall. He had pretty much resigned himself to the fact he was going to die. They patched him to his wife who was in new zealand. He was on a radio patched into a sap phone. We dont have sat phones at 28,000 feet. Well, the entire story is told in the book everest mountain without mercy. Then you have a movie coming out. When we come back to a second look. The phone record of mallory and irvines trip to Mount Everest. Stunning images preserved forever and coming to a bay area theater. And the balance between exploration and conservation. Still ahead on a second look. Thats a negative. Whats that alarm . Fuel cell two is down. Im going to have to guide her in manually. This is very exciting. But im at my stop. Come again . Im watching this on the train. Its so hard to leave. Good luck with everything. With the uverse tv app, the uverse revolves around you the uverse revolves around you tonight on a second look, the first to conquer Mount Everest. Many people have tried to summit the peak and failed. One of the biggest attempts was mallorys expedition. It was mallory who famously responded when asked why he wanted to climb everest, because it is there. It was beautifully filmed with a hand cranked camera. It will play at the castro theater. It wasnt until 19 years after the mallory expetition that two men made it to the top of the mountain and returned to share their story. Edmond hillary and norway reached the peak at 11 30 in the morning on may 29, 1953. The two spent only 15 minutes atop the mountain. As hillary told the story, both men reached the summit at the same time. We had been climbing together. I think we became a fairly heavy pair. This was just one example of how together you are. And how one is always protecting the other. I was leading down the asphalt. When i was passing a crevase a large piece of ice came down. And he pulledded me up so i didnt go very far. How did it feel up there on top of the world . Very happy. In 2003, sir Edmond Hillary sons talked about how he celebrated the 50th anniversary of his fathers achievement when climbing that mountain. Theres a lot of times you want to be some where else. Because the jet stream blasting over the top. But when you reach there its incredible uplifting experience. Its very exciting. So you took a film crew along with National Geographic. The pictures from there are spectacular. This is the highest point on plant earth. Its not easy to get this footage either. We nearly had both of our camera men killed in a terrible collapse. A very dangerous part of the climb. Its a taxing sort of experience. You can see there the jet stream blasting over the top of the mountain. And at that particular occasion it destroyed many of the tents are completely wrecked. You have to drop back down to base camp, regroup and give it another go. This is no weekend hiking expedition. People have died up there. Over 200 people have died up in the mountain. Its not a weekend either. We were is there for 21 2 months. And your dad was the first to get a sherpa guide. You went up once with your dad. That must have been something. I went up with my father. When we got up in 1990 we were the first father and son ever to reach the summit. I my dad was up there in 1993 and i was up there in 1990. Last year we went up with the National Geographic team to celebrate the 50th anniversary and produce this film. Your dad looks great by the way at the age of 83. He looks like hes in great condition. We had this Amazing Party here in San Francisco. 1,000 people just to celebrate that 50th anniversary. And there were 60 locals were at the celebration that made it to the top of everest. E didnt know there were that many from the bay area i didnt know there were that many from the bay area. They came from all over the world and there were some sherpas. Theres word that its getting too crowded, too polluted. Many people are leaving their trash. Is it getting too crowded there and would you like to see some restrictions. Look, you know i think we have to realize that the nepales have arrived today have a Tourism Industry just like we do in the west. And what we need to hope for of course is that there are reasonable restraints put on people in terms of the impact on the environment and local peoples culture. But it really is a very important industry for them. I look at this as the shuttle launches. As adults we react to it differently. What do you hope kids get from this. When they see your documentary. Its about going on an adventure. Working as a team. That great goals, successes dont come easy. You have to do your ground work, you have to do your apprenticeship. And i hope that they give something back. Its something i do as i go back once or twice every year involved with the work of 42 schools and hospitals around the foot of the mountain. And i hope that the people that trek with me back into this area really want to have a great adventure that you learn you can make a difference to People Living in very poor conditions.
