Steep rollover at 7200' in uncompacted terrain. Cracking noted in similar terrain. This slab had no wind effect and just enough cohesion to propagate 40' wide and 16" deep. Weakness was 1mm facets sitting just above an inch thick temperature crust.
Total snowpack there was 2-2.5'.
Very poor snowpack structure - 12" new above 4" very weak cohesionless squares above a 1" thick temp crust - as well described by Evelyn here the day before. Any significant storm at this elevation would produce a significant avalanche cycle. Unfortunately, the weather forecast looks a bit grim.
