I found multiple incact weak layers formed earlier in the season on north-facing slopes. The most recent crust/facet layer was distinct but not reactive, despite the slab above it being around a foot thick. The recent snowfall seemed well bonded to it in this area, which was a bit sheltered near treeline. The 3/13 facet layer around 50cm from the surface did propagate a fracture in ECTs (ECTP23). Higher up in the alpine below a wind-loaded ridge, the stiffer slab above this layer was not as well bonded. Recent winds have not been super strong and new slab formation was moderate to minimal.

Vail Pass to the terrain above Lost Lake and back

I dug on a north-facing slope at 11700' and found all the layers of concern we've been tracking. The warm-up at the end of March formed a stiff 5cm crust, but it didn't appear that water had percolated into deeper weak layers. The 3/13 and 3/3 layers were still very evident and reactive with some force. It would maybe give me a little pause on steep, north-facing slopes in open bowls with well-connected slabs. The basal facets from Thanksgiving had gained strength, and were not much of a concern.

Chilly to start the day with high thin scuzzy clouds across the sky. These clouds started to burn off around 11:00am.
