Mile 780: Forrester Pass
May 21st, 2017: Easy approach on hard ice/snow started at 5 a.m. Moved directly up steepening snowfield using alpine snowshoes. Gained last several switchbacks that were partially uncovered. Switched to crampons for switchbacks and ice chute. Ice chute already had steps across. Easy with ice axe and crampons. Not much of a cornice. No technical climbing required after ice chute. One of the easiest passes. Descent was straightforward and involved a pretty much mandatory, massive, steep glissade. -Beta.
June 12th, 2006: Approach to the bare switchbacks (top 1/3 of the switchbacks) was heavily sun-cupped. Snow chute at the top was ~30 feet across. The afternoon descent was tedious, crotch-deep postholing. Moving ~1 mph downhill.
June 14th, 2011: Direct approach up the steep snow field. Snow steps were already cut across the snow chute. Cornice at the pass involved class 3/4 rock climbing to bypass. Knee-deep postholing and glissading descent. Camped around 9900 ft on dry ground.
July 13th, 2011: Snow field approach was short before the switchbacks. “One of the easiest passes”. Icy snow chute was short and not a problem. Glissades on the descent were stopped by sun-cups.
