Did a quick trip through the Bugaboos September 3-4. Into the Kain hut for a night then out via Cobalt Lake.
The Bugaboo-Snowpatch col looked unappealing and dangerous to me. Lots of potential for natural and climber generated rockfall, and steep ice into gravel and loose boulders to exit. See pic.
The Cobalt Glacier is bare ice with a 3-4 decent sized crevasses near the top that are visible and easily avoided. There were lots of perched boulders on the melting ice though and potential for rockfall exists. We were able to move quickly through here but in hindsight I won’t go here again this late in the season.
Other than that this was a beautiful trip with fall colours just starting to come out.
