Quick report
- Collapsing
- isolated
Toured to Avalanche Bowl and dug a pit on a north-facing slope at 9,000' to investigate how the abundant weak layers are reacting to the current loading event. Most notably, we got an ECTP 18, 47 cm up from the ground. Propagation observed on 3mm facets below a crust. It's worth noting that a pit dug in a nearby location on Thanksgiving (11/23) did not produce propagation in any stability tests. Propagation in this pit is likely the result of a slab beginning to develop in the upper portion of the snowpack. See attached video for pit results and more info.
Noted one collapse on an isolated wind loaded pillow. No observed avalanches.Weather

Snowpack
About 6 inches of low density snow had fallen by mid morning. We noted lightly wind-stiffened surfaces on exposed leeward (N/NE facing) terrain. Sheltered terrain held unconsolidated powder sitting on crusts, facets, surface hoar, and bare ground. Snow depths are approaching 3 feet (1m) on north-facing slopes at 9000'.
