Observed avalanche activity: Yes
Avalanches: Numerous recent D1 – D1.5 avalanches on Schuylkill Ridge and a few D2, on E-NE aspects N/BTL. A few D1.5-D2 in Redwell Basin as well. See photos. Looks like most of these ran during the storm on Friday, but a few look crisp enough that they might have run yesterday.
