Observations

Toured Shuksan Monday 3/8 including White Salmon, Upper Curtiss, upper Sulfide, Crystal, and upper Hanging Glaciers. No instabilities noted during our tour. Did observe large (6'+) crown on Nooksack Glacier headwall, possibly from cornice failure, though cornice above looked complete. Based on snow accumulation on the debris below, the slide happened a few days earlier.
Also, a few small (1'?) crowns below Hanging Glacier, NWC, and western edge of White Salmon around 6000', all a day or two old.
