Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Temps reached a high of 29°F during our tour and snow was heavy at times reaching 1cm an hour. Moderate SW winds were observed near independence mine at 12:45pm

Snow surface

6-7" of new snow fell early this morning and thought the day. Ski penetration average 40cm for most of the tour.


During our short tour we observed that the snowpack has poor structure, moderate strength, and low propagation potential. While traveling we were unable to locate a cohesive slab. We dug 8 different pits in this location and none of them had propagation during any large column tests.
