Mammoth Rock, Sherwins

Toured up in to the Sherwins via the standard route adjacent to Mammoth Rock up to the base of Mammoth Rock Bowl then over toward The Hose. Limited visibility prevented good visual feedback throughout the tour. Frontal passage appears to have occurred around 400 PM with periods of moderate to strong winds, snowfall rates of 2 cm (~1") per hour or greater. Consistent 10 to 20 cm new snow over a melt/freeze crust observed throughout but variable coverage due to winds. Minor cracking around tree-wells(length of ski) with drifting of 30 cm  or better along the ridge directly above Mammoth Rock. 1 small natural Wind Slab failure (D1/R1-), Poop Chute. Wind Slabs forming above ~8000' where sufficient new snow exists for transport, potential increases with elevation. Hand shears easy to failure on isolation, ~10cm thick (~4"). Test slopes yielded only surface sluffs. Scattered old now frozen rollerballs below ~9500', which were a ski hazard. Two rather large debris fields observed from the last avalanche cycle (4/6-4/8). Lower Hose ~ 9200' failed with debris pilling up in the trees (~8300') with several 20 cm  plus (~10") trees embedded in the debris. Debris looked very wet in nature due, large chucks and a very narrow and tall debris field. Second debris field was under Mammoth Rock, start elevation ~8700', again large chunks. Both ENE aspects.
