We backpacked into willow lake and climbed Mt. Adams and Columbia Point, the two centennials that I missed on my blind 14 hunt, as I passed through this valley years ago... weather was challenging, with fog and clouds constantly blocking sunshine, and highs in the low 30s. Conditions were brutal. Several inches of fresh snow clogged everything above 13,300 feet. The 3rd class couloir up Columbia's tiny northwest face was coated in verglas, and choked with snow in many places. The Kit Carson Avenue was full of snow, and full on treacherous while frozen. Challenger's standard route is pretty good but has some unavoidable snow crossings. Mt. Adams was pretty bad, with a frustrating 8 inches of powder on its upper slopes. All in all, successful trip, but only because of lucky weather windows, and comfort/competence on serious terrain with snow and verglas.
