Snowpack

• Snowpack Description: Washington Gulch Tour - 20120226 @1215hours Full Profile Snowpit @10,600ft. 30* NE Aspect just below ridge line and south of main Coney's ski shots. Site was protected from the wind however had wind blown snow atop the layering. Sky: Few, Precip: NO, Moderate Westerly Winds with Moderate Blowing Snow Boot pen = 40cm, Ski pen = 15cm HS = 132cm 37cm slab of 1F resistance 30cm slab of 1F resistance 15cm slab of P resistance 15cm slab of 1F resistance 35cm (to the ground) depth hoar of F resistance [grain size = 3mm large facet crystals] No cracking or whomphing observed CTM (PC) results, failure 89 cm down. Failure was at interface of depth hoar layer and was irregular. Column collapsed but did not slide. Snow shearing observed in the upper layers of the snowpack. Results where similar for Deep Tap test. DTM (PC) results, failure 89 cm down from top of snowpack. ECTX. After 30 loading steps I hammered the shovel with a closed fist and finally initiated a failure after 4 hard hits. (BRK) failed interface of depth hoar. Showing low potential for propagation. Skied main gut of Coney's, no signs of instability. Skiing was mainly on dense wind crust that was penetrated during ski. At bottom of our run we watched 2 snowshoers walk up to a steep wind loaded slope at the base of Coney's and trigger a slide. Estimated HS-AS(Snowshoer)-R1D1-I. Estimated depth of 6-12" running maybe 30 ft. Snowshoers we not caught and walked back out of danger zone.
