Weather
High 20's F, clear and breezy with 10 to 20 mph west winds at ridgelines.
Snowpack
Approximately one meter snow depth on north/northeast and a half meter on east aspects. The bottom half of the pack is course facets caped by a 5 to 10 cm thick supportive ice crust overlain by a less than 0.5 cm layer well developed facets and then the December storm snow. The crust is absent in many places on more dead north facing aspects. This crust is the interface of the avalanches observed on my tour
Avalanche
I remote triggered three avalanches on the November/December storm interface, two of which I triggered from what I estimate to have been over 200 meters away
