Colorado man among rescuers in Everest tragedy

The window to summit Mount Everest was death's door for at least four climbers, but a few others may live because a local man was helping with rescue efforts.

Jon Kedrowski was near the summit of the world's tallest mountain Saturday when the weather changed and 100 mph winds trapped dozens of climbers, Kedrowski said.

Read Kedrowski's blog here. His team is gearing up for another summit bid in the next few days.

It's being called the worst Everest tragedy since 1996, when eight people died. That event was the subject of Jon Krakauer's book, “Into Thin Air.”

Kedrowski said there was a two-hour wait at one of the main chokepoints near the summit, as more than 150 climbers attempted to summit during Friday and Saturday's brief weather window.
