Red Flags
Collapsing, Rapid Warming, Poor Snowpack Structure
Red Flags Comment
<p>Two audible collapses on flat ridges. No fractures propagated given the angle.</p>

Wind deposited E slopes are much more sketchy than anything else around the compass. High pressure has built some nice surface hoar and crusts to keep us weary after the next storm rolls through.

Instability Comment
<p>Pits on NW/W @ 9400' yielded mixed results. A few columns fell at the ground when isolated, some a few feet over took a beating and never broke. Right now, the Christmas rain/rime crust is the most consistent offender, consistently failing as ECTN from the wrist/elbow. The snow is strong and strengthening over this layer, but sits atop the knife crust, which caps bottomless facets. Any E/NE aspects that haven't gone, could go big with a trigger. Wind-scoured W/NW have less of a slab and are pretty rigid. Conditions are extremely variable in the Logan area, and local tests don't mean much for the next pitch over.</p> <p>Some warming, but not enough snow on wind-scoured, high southerly aspects to do much.</p>

The usual high pressure mixed bag of conditions depending on aspect, elevation, local topography, etc. Depths varied from 10-20cm on S/SW aspects to 120 cm on sheltered N/NW/W. Fast surface conditions.
