Forecaster note: Date unknown, so I just chose an older date.

Observed what appear to have been some wind slab crowns on the NE side of the Pfeifferhorn N-NE facing around 10500'. Below the east ridge. Didn't go up to inspect the crowns, looked to be 12"+ deep, largest one around 100' wide. Lots of smaller pockets looked to have gone in the rocks above the lower apron. Could see similar looking pockets that came out on NE-E aspects on the satellite peak west of Pfeifferhorn. Not sure when these occurred, but would estimate they happened since between today and Monday.

Snow was pretty wind hammered and heat effected in the alpine of Maybird. Not much quality snow found to be skied.
