Snowpit Observations
More detailed information about the snowpack: 

Traveled to Aspendel to assess: access, recent new snow & its transition to corn snow, upper elevation avalanche observations, and spring snow stability.

Above ~ 9000’, still snow from the road (either Sabrina or South Lake) with approx. 1 to 1.5 meters ( ~ 3’ to 5’). Surface snow 4cm Wet Loose over 10cm supportive melt/freeze crust resting on ~20 cm wet rounds. The supportive crust near and around rocks and vegetation at times became less than supportive. Recent new snow has melted off below ~9000 and is transitioning toward corn quickly above. Some roller balls observed from a couple of days previous, was able to release new rollerballs on steep WNW aspects. Quite warm 12.5 C at 1:30, 10,000’, top 3-4 cm wet. All but north aspects had signs of Loose Wet releases over the past couple of days, some running over ~1000’ vertical. Rollerballs observed on all aspects below 10,000’. Few observable tracks scattered throughout the backcountry. A few Glide Cracks observed primarily in the Alpine and a few upper Mid Elevations, both open and bridged. Skiing good, if your timing is good, a bit wet and slow if you’re too late.
