At least 4 of the 7 sisters had slid, likely Sunday during the storm as the snowfall changed from light and blower to very dense and wet. There are likely slabs on the other 2 as well. Some of the more difficult-to-see avalanches had broke along the cliff bands of what we've always called "Gnome Peak" (ridge Southwest of Mt. Elmer)
