Hundreds of climbers are expected to try to reach the top of the world's tallest peak, Mount Everest Thursday and Saturday.
A break in the weather is expected to give them a brief window of opportunity during what's been a particularly bad climbing season.
More than 200 climbers tried to reach the summit last week. Four of them -- including a woman from Canada -- died in one of the deadliest days ever on the mountain.
With its icy terrain, high winds and sub-zero temperatures even the most experienced climbers say Everest is one of the most unforgiving places on earth.
