Tony on a Peak at Glacier National Park, 1988 We actually intended to climb the neighboring peak across the valley, as it was 10 meters taller. We made a huge navigational error on the approach, which was due to a collective hangover amidst the group, and the fact that we speed-climbed the peak in two hours. We were rewarded with a bonus at the top of our "oops" peak: there was an 1800-foot sheer wall on the south side that bottomed at a glacier. We started dumping huge rocks over the dge and listened to them hum and vibrate and land on the glacier below, in a slow-speed cratering effect. We slide-dumped some rocks that weighed up to 1000 pounds. The effect below was surreal. I really hope nobody was hiking across that glacier.
