Observations

My partner & I made our way up to Source Lake then had to decide where to go from there. Pineapple Pass was pretty tracked out. Bryant Couloir looked untouched & super inviting, however we were a little worried about the sun-baked cliffs hanging over it. We decided to head up towards Snow Lake Divide. We followed several groups up the apron then split off to head towards the Divide. We found a small shelf before the top where we transitions. We had noticed some firming of the surface from the sun so we tried to avoid the open convex roll-overs. While we tried to move around one roll-over we didn't give it quite enough room & triggered a small slide the broke down to a chalky layer. Another small slide remote triggered so we didn't stick around to get investigate or take pictures of the slides. We continued to mellower, trees slopes below. Great riding & no other incidents.
