Comments
Route was up Lees Fork to Reynolds with a Mill D exit. South aspects were dry prior to the recent storms, so there are no PWL issues. Southeast aspects up to 9,500' are shallow (less than a meter) with different facet/crust combinations. On one pit on a SE aspect at 9,000', the block would fracture upon isolation, failing in weak facets underneath a deteriorating crust. The setup of an incredibly poor snowpack structure is in place and in areas with some wind-loading, we are seeing natural, and human-triggered (as well as remotely-triggered) soft slab avalanches failing on the PWL (December Drought Layer). With strong winds and heavy snowfall forecast this evening, we should have a slab distributed more evenly across most aspects.
