Zone or Region:
June lake Area - Low elevation South East ~8,300 Ft.
Went for an afternoon walk in low elevation south east facing terrain - where it was sheltered from wind the new snow came in nicely; however, at about 10-14 inches below the surface a sun crust with a weak layer underneath was present. The weak layer was reactive on a test slope resulting in a sizable slab - below the weak layer on this aspect the snow is firm and smooth.
Down lower at approximately 7,700 ft elevation we triggered a sizable storm slab on a test slope. This area had no weak layer present but the new snow had bonded together well with the smooth firm old snowpack underneath.
Did you trigger any avalanches? Yes
Was it intentional? Yes
Size 2: Could bury, injure, or kill a person
Small trigger on a test slope - results were enough to indicate that if triggered unintentionally this could result in a larger more consequential avalanche.
Did you see shooting cracks? No
Did you experience collapsing or whumpfing? Yes, Isolated
