Quick report

I went for a jaunt up the morraine to assess wind transport, how warmth and greenhouse were affecting snowpack, and to search for the midpack crust/facet structure.

I found various surface conditions, and a relatively similar snowpack structure throughout the moraine. I found the crust/facet layer combo 50 - 60 cm down in this area. I got CT M RP results. The crust was variable in thickness and hardness, and the facets were consistently very small. 

For the most part, snow was moist top to bottom up to 8500'. Moist surface snow was found all the way up to 10700'. Certain terrain features helped to preserve soft, dry snow at all elevations. Lower elevations held mostly surface crusts by the end of the day. 

Various debris fields observed from the last 48 -72 hrs. Wind slab and loose dry. Crowns hard to make out.

Cloudy skies and warm temperatures contributed to greenhousing at lower elevations. Temperatures remained a bit cooler as I approached 10K. Winds were light. The day felt humid.
