We traveled into seldom-traveled terrain to get a good look at the snowpack.
As always, many thanks to the hospitality of the Powder Mountain ski patrol.
Snowpack
- Instability Comment
- <p>The December Drought Layer (DDL) PWL is buried 30-60 cms deeply and in thinner snowpack areas, we got collapsing on this layer. Two extended column tests on a southwest and west aspect got full propagation (ECTP12 and ECTP14) with a 4F slab on top of the PWL(Video and photo below.) We also got a fracture and propagation on isolation (PSTPV) when performing a propagation saw test.</p> <p> </p> <p> </p>
Dense snow with drifting and fresh cornices along exposed ridges.
