Ascend snow (early season) or talus to glacier (no crevasses but can be icy by mid-season) and follow glacier to Colchuck Col. A couple of hundred ft. left (E) of the Col, ascend the couloir to a notch in the ridge (Pandora's Box). Drop down and left, then traverse left (NE) to the summit; some parties use ropes for this part. Alternatively, about 30' below Pandora's Box, exit left and scramble up 4th class rock about 20 feet, then follow the ridge line left. In early season, almost the entire descent can be glissaded. But use caution; serious accidents have happened glissading from Aasgard Pass. The ascent and descent can be reversed but the route-finding to get to the Col can be tricky. No credit is given for ascending and descending via Aasgard Pass. Permits are required. Check with the Forest Service for access restrictions and trail conditions. Recall that Pandora's Box was filled with - among other things - deception!

This is a long day climb with a brisk pace. Please make sure you are comfortable moving at a brisk pace.
