Quick report

Collapsing
isolated

We did Stormies in the morning and we didn't see any signs whatsoever. About 80cm of fresh snow at 5000' on crust. After we went and did Moonlight. We did a test profile just before dropping in at 5250', which is in the photos section. The profile didn't produce many yellow flags. At the point we finished the profile, the sun had significantly heated up the run, with rollers present in places. Upon skiing down, the snow did collapse at about 10cm deep as we skied, but the chucks were rather small and didn't move far. This was only for the first 100' vert. The sun forced us to chase shaded slopes, so we went up to skyline ridge and skied down into the valley, stopping just under 4800'. We did see collapsing in sections of this run that were similar moonlight. We then skinned up to the top of Tye and skied down the NW side to Tye Lake. To our suprise, there were no signs of instability on this slope. We skinned back up to Tye and did a second lap. That time, we dropped more aggressively into the run right off the summit of Tye on a 40 degree plus slope. Not even a small dry loose. We skied down from the Tye-Sky saddle and skinned back up the other side to exit.
