It's hard to call the snowpack structure poor... its beginning to lack structure altogether.

Comments

A few interesting discoveries were made during travels near Duchesne Ridge today. The most notable would be the return of cracking and collapsing, but only in the wind zone The new snow seemed to need to be "indensified" by wind in order to communicate a failure over any considerable distance. In avalanche terrain in the area, this notion is almost visible on slope: loaded start zones with fat, stiff, wind deposits, uphill of a really visibly thin snowpack (see attached photo). The second discovery was a snow profile containing almost entirely weak snow. Present is the slightly-rimed buried surface hoar that has been found elsewhere (see attached photos). These grains are hard to photograph due to their now "crusty" appearance, likely from rime when buried on 20251130.
