2 short steeper sections in small open areas within the trees produced non-trivial sluffs that entrained the newest (Saturday night/Sunday) lower density snow and generally stopped at the interface to the somewhat denser snow from Saturday.Signs of Unstable Snow
None reported
Observations
The layering in the upper snowpack with very low-density snow on top (6-10 inches in the trees), higher density snow from 12/11 below that, and another layer of softer snow beneath from earlier in the week was easily observable using ski poles. Below 4k feet the denser 12/11 snow was highly prominent. from 4k-5k this layer became more and more subtle but still easily detectable without digging. No signs of slab instability or propagation with test slopes on convexities and short steep sections producing no slabs, cracks, etc. - just the loose dry activity noted.
Weather was about as expected. Calm winds in the trees, possibly a bit warmer than expected, and intermittent snowfall up to S1.
