Quick report

Recent avalanche in southern gully of Jawbone Canyon complex. I imagine there's more of these side slides as you get into steeper terrain The last major "storm" threw alot of wind at us, creating lots of features created by wind, and also lots of scouring by wind. Since this event, temps have remained cold, in the teens at night and 20s during the day. We received ~4-5" of light floofy snow on 3/14 evening, followed by lots of warming to mid-hi 30s during the day yesterday, making for heavy snow. More rollers observed at this point in the season to date, and I think we can expect the steeper side slopes that normally slide to do just that during the warmer parts of the day.

The snow we just received was very light and poofy, situated on top of a hard wind-capped surface. Notable weather shift yesterday from teens in early morning to mid-upper 30s F during the day. This rapid warming made the snowpack slush-ify by mid-late afternoon. No wind but lots of wind features from the last storm.

Snowpack

Snowpack depth of 100cm. New layer has big grains and was melting quickly. 100-92(4F); 92-90 (1F-pen); 90-50 (3F-2F); 50-47 (1F-pen); 47-20 (3F); <20 (shrub, unconsolidated). There were two really hard layers in an otherwise pretty consistent snowpack. Quick pit @ 9400 ft on e- aspect within a few hundred feet of the avalanche reported

Avalanche

The avalanche observed occurred before the most recent storm, appears to have been a point release from the rocks above.
