The snowpack was measured at ~97cm with some minor loading. Small (2cm) "scabs" were observed naturally sliding. The snow surface was wind effected. The observation was consistent with those made on Gray Butte on Dec 9. CTN (25+ strikes with no activity) but when the block was being sheared into the pit, it broke very easily about 70cm down on a Q1 surface that showed varied size facets. This was below the rain/freeze-melt layer roughtly between 20cm and 40 cm from the ground. Something interesting to see! Also, a good reminder for variability and to watch out on thinner snowpack areas.
