Comments

Two naturals noted...the lower one looked like it ran at the end, or just after, Sunday's storm. Edges looked sharp with little to no new snow. Based upon the holes we dug in the snow, we felt that the 'recrystallized' graupel was the weakness. It was evident in our pits and seemed a likely spot where graupel would pool from the slope into the gully - where both slides released.

The one below may or may not have been triggered by sluffs from above. The thing is, the sluffs looked like they had a couple inches of new snow on them whereas the hard slab did not.
