Saw several natural avalanches on the headwall between Ben Lomond and Willard Peak, which released near or just below the ridgeline. Based on the signficant cross loading visible from a distance, I imagine these were wind slabs, likely the result of the very strong overnight winds 16-17 January. Slides were many (almost one per drainage on Ben Lomond), size D1 -D2, the longest running with perhaps 400-500ft of vertical drop.

Not sure the photo quality does it justice for these, given the distance. In this photo of Willard, slide debris is visible below the left hand ridgeline above the sun/shade line.

Most of the activity in this photo was in the NE facing terrain in the bowl on the upper left of the photo, debris stopping at the mid-slope bench.

The longest running avalanche was in the summit drainage, just looker's right and near the base of the trees, running through the rock choke and stopping in the drainage a few hundred feet below.
