Prominent ice crust at 70 cm depth, slick surface, but could not get block to slide on it, even on a 36 degree slope. ECTX, CTN.

Location - ALP, open convex roll Objective - Investigate Persistent Facet Layers Other Test - DTH 28 (SC) dwn 110 FC Ground Cover - Rocky, Boulders, VAR HS 150-200

Height of snow is not measurable by 300 cm probe. Snow pilot will not let me state that.

Overcast, light snow, westerly winds, 5-10 mph, with gusts to 15 mph. Approximately 2.5 cm of new snow over 30 cm of melt forms over 100 cm of old wind slabs over 15 cm depth hoar. Most of the snowpack is composed of rounded grains or facets becoming rounded. We performed compression tests and an extended column test and observed CTM 12 at 15 cm below surface and ECTN 12.

slope collapsed (5m radius) on stomping out a turn in skin track. pit was dug 3 m in and upslope. all slope measurements were <28 degrees.
