Comments
Hiked into Broads & found a large natural avalanche on the apron below Diving Board. Looked to have started off the rock slabs above the apron. Initial width of the crown looked to be 30-40ft. Slide propagated on the apron to close to a football field wide. & ran almost full track. Timing is uncertain, but may have happened overnight. There was a dusting of new snow on the debris. Having a safe way up, we decided to ski the side of the side. Poking around on the way up it seemed the bed surface was the rain crust or possible wind crust. Skiing down, it was apparent the rest of the apron had slid in the past as there was buried debris. Slow mo snow due to very cold temps.
