Avalanche Forecast
Regions: Glacier.
Watch for pockets of windslab in isolated Alpine lee features.
For now, the bigger danger is returning to the parking lot from your day's mission. Many rocks/stumps/obstacles remain at or near the surface in the valley bottom. Slow down, maybe walk if you have to, to save yourself from breaking bones or gear.

Avalanche Summary
Natural avalanche activity has dropped, along with few reports of human-triggered avalanches.
A field team near Fidelity was able to ski-cut steep convex rolls, resulting in small, slow-moving loose sluffs.
Snowpack Summary
Variable surface conditions exist in the Park, with wind affected snow in higher Alpine areas and 10-20cm of settling snow in sheltered terrain features.
The Nov 9 crust, down 50-100cm, has had limited test results on it. The base of the snowpack is comprised of several dense, melt-freeze rain crusts.
Treeline snowpack depths average 110-130cm.
