Quick report
The skin track is melted out to dirt in places on the lower skin track from the trailhead, and the unpacked snowpack is barely supportable with a flimsey crust. Above 8000' elevation, the crust became fully supportable, growing to 4-5" thick. There was 9" of new snow that was bonding well to the crust. No cracking, collapsing, or slab avalanches. Conditions were calm and warm, with intermittent graupel showers. No wind loading.
There were many wet loose avalanches beginning at 11 AM. We first saw them coming from the cliffs above Exit Chute, and saw one initiate in the Tyler's slide area when a tree shed its snow. None of these slides ran far, but that was largely dictated by the terrain. In longer, steep terrain, these would have entrained significant volume and been dangerous, especially in confined terrain.
We were on our way out by 1 PM. The new snow was moist and sticky; I don't know of a ski wax that would have slid well. The moisture in the new snow was beginning to lubricate the interface at the crust, and one could push ski width, wet loose avalanches downhill.
Conditions likely continued to deteriorate later in the day.
Wet loose avalanches from rocky slopes and in steep terrain triggered by skiing.Weather
