Comments
Strong winds this morning were having their way with our low density snow from the weekend. North slopes were loading at a rapid pace and on the south side of the ridge it has been scrubbed down to almost the brush and rocks depending on the exposure to the wind. Stiff wind slabs were all along the ridge so I expected to see something, I was just surprised it was not bigger. It appeared that a natural cornice drop had triggered a small wind slab just off the ridge. It kind of just gouged a trench down into the trees below and stopped. Sorry no pictures, to dang cold to get any.
