Right now, 250 daring men and women are climbing toward the summit of Mount Everest, the highest point on Earth. Some will succeed. Most will fail. Seven will die.

Team Discovery feels the wrath of the World's Tallest Mountain, and must turn around due to bad weather.

Ben Webster maneuvers his climbing party to the head of the pack, but more bad weather forces them to stop cold - and allows other teams to catch up. Despite the weather, some climbers decide that they want to risk the danger of going ahead.

Climbers have been living on Mount Everest for over a month. They've grown accustomed to this environment. Everest is their life now, and the acclimatization process is finally complete. That means it's time to lace up the boots and go for the glory.

As climbers are struggling to breath without the oyxgen they're used to, how many climbers from Team Discovery will reach the summit?

On the last episode of Ultimate Survivor Everest, Team Discovery climbers Andrew Lock and Hector Ponce De Leon made it to the summit of the world's tallest mountain. While diabetic climber Will Cross was slowly heading to Camp 3, Mexican climber Andreas Delgado was suffering through his painful attempt at summiting without oxygen. Watch the conclusion of this stunning adventure.
