Saw evidence of numerous previous slides, size ~2.5 debris pile on first photos. Most any open slope had a crown at the top buried but about 30cm of soft snow and debris pile. Sliding surface seemed to be rain crust maybe from Monday? A quick hand pit showed an easy shear above the crust. No fresh slabs observed, but some point releases and sluffing. Approach was a bit of a pain with numerous (20?) creeks across sky pilot road requiring various crossing techniques and wet snow adhering to skins until the end of the road elevation.

Unsure of Avalanche age or if hazard persisted. May have been induced by wet weather Mon, but debris piles were not ice chunks as may be expected
