Soft slab, natural avalanche observed at 1030am on the northern shoulder of Reynolds Peak. Viewed from Tom's hill. There was intermittent fog, but am pretty sure that this slid between 930-1030am. No tracks observed going into or out of it. I could not see how far the debris ran because of the trees. The image is fuzzy due to the distance. We skied slopes below 30 degrees and did not observe any other activity. I ventured off the skin track down low and could feel the snow collapsing when I stepped. When I dug down I observed different densities within the upper snowpack.
