We observed some wind loading and solar radiation activity including rollerballs and heavy snow where the sun was hitting it. This slide appears to have happened after the snow events we had earlier in the week. No observed instability.

Clear, sunny day. The winds at and just above tree line were moderate. We could see snow being transported along the ridgelines. Temperature at 4k at 10am was in the 20's. 30's by the time we reached 1600' at 11am.

Snowpack

This path likely slid during the snow event days prior. However, we observed a warming snowpack and some rollerballs around 10am while we were in the area.
