I have seen The Eiger Sanction. I almost got hit by a falling rock. It clipped the right shoulder of my parka, but did not hit me. Then on the descent almost got caught in a HUGE icefall avalanche from the hanging glacier between the Eiger and Jungfrau. It was ice about 300 ft high and about 1500 ft wide. Missed by about 20 ft. Lucky we were not a bit faster.
How realistically did the movie portray the mountain?
The blocks of falling ice were the size of railroad cars and went on for about a minute. We were blasted with ice shards and snow. We were trying to outrun a storm that had lightning hitting all around.
