Today we rode sleds into the southern Missions and toured on skis along Mount Henry. We found widespread crust-facet compo on all aspects, 1 foot down (30cm). We found isolated cracking on ridge tops and propagation in extended column tests in wind-loaded zones.
We intentionally triggered an avalanche on an east-facing slope at 6900ft on a steep rollover. The slope angle was 37° at the steepest and an average of 34°. The size caught us off guard. Measuring on a topographical map, we got the approximate size of the avalanche, 200 feet wide, running 250-300ft downhill. (HS-AS-C-R2-D2)
