We stumbled across these recent large wet slab avalanches, looking down into South Hollow from the Sunday Camp Saddle in Providence Canyon. The broad and deep slabs appear to have been triggered by wet sluffs that initiated in the rocks above and overran the steep slopes below. The avalanches ran on basal layer depth hoar, cleaning out the entire shallow winter's snowpack... I'm not sure when in the last few days these ran, but I'm guessing on the very warm ides of March (3-15-2012)......
