Snow Characteristics Comments
Trace of new fluff overnight. Feb 14 storm (exactly one week ago) put down 18"-24" of new snow, the first significant storm since December. Much "trenching" was observed from snowmobiles that had been out not long after the storm, with obvious dense snow on top of weaker faceted snow.

Red Flags Comments
The Feb 14 storm more than doubled the snowpack on shady aspects, sun exposed slopes were bare. As expected, the underlying snowpack was entirely faceted and interspersed with a thin melt freeze and one very dense melt freeze layer. Surprisingly, an extended column test produced a score of ECTCX. I did observe deep cracking on a steep gully wall that likely occurred during the storm event.
Comments
This was my first trip to the Abajos in some time. The season has been very dry down there with only about 12" of snow on the ground in lower North Creek, as little as 6" at Camp Jackson on the south side of the range, and 18"-24" on upper elevation northerlies prior to the Feb 14 storm which brought an additional 18"-24" to the range. South facing slopes have been dry. I did not observe any avalanche activity from the last storm event, presumably due to overall lack of connectivity, the poor snowpack structure is surely there.
Overall coverage remains quite thin, then last storm being the only snow on solar aspects. All of the slide paths threatening North Creek drainage have thin starting zones and almost no snow on ESE facing sides of the paths. Poor structure does exist on northerly facing slopes, but avalanche terrain is difficult to access, and the likelihood of triggering an avalanche seems minimal at this time. Outlying pockets of drifted snow exist over weak snow on some of the more common slide paths in accessible areas, but due to lack of connectivity, avalanches would be small. Very few slopes, in extreme terrain, are capable of producing D2 avalanches. More snow, will of course change things.
