From obs 5/12/24: "Saw a few slides that look like they propagated across the layer of new snow from the last storm (as opposed to the characteristic spring wet snow point releases). The largest was the previously reported one from Sheep... We also saw a similar slide on a N/NW aspect of Mt Zimmer (pictured). Hard to say from a distance when these broke, but the one on Mt Zimmer looked the most recent." Photo: A. Kautzer

The largest was the previously reported one from Sheep. On the way out we saw a smaller slide farther south along the same ridge that looked like it broke on the new snow interface, both NE aspects (pictured)." Photo: A. Kautzer
