Quick report

Dry Loose avalanches may continue to be pushy and fast in steep terrain, running on the 2/7 crust, as cold temps preserve low snow densities.  Great skiing!

Very small, non-destructive Dry Loose avalanches were running naturally from steep solar features throughout the day. Ski cuts on steep terrain easily triggered Dry Loose avalanches that entrained all recent storm snow and near surface facets above the 2/7 crust (25-35cm depth).

Snowpack

A profile on a N aspect @ 6300' held a total snow depth of 300cm.  16cm recent low-density storm snow rested over 11cm recently buried near surface facets from 2/13.  This F to 4F hard snow all sat on the brittle  2/7 crust with a fair to poor bond.  Lacking slab structure, stability tests were unremarkable.  However, ski cuts easily initiated entrainment of the upper snowpack, running on the firm bed surface of the crust. 

Persistent grains exist in the mid-pack, in association with the 1/28 crust interface, but are unremarkable in tests.

Very good skiing on colder aspects overall, but steep terrain remains scratchy and very sluffy.  Unsupported steeps may become questionable as slab structure builds in the upper snowpack.
