General Comments

 Deep slabs reared their ugly heads in the Ogden  They were reported in the Powder Mountain backcountry  and broke 4-5’ deep and up to 200’ wide. I don’t have complete details, but believe these pulled out on north to east facing slopes beween 8500’ and 9200’. The deep slab in the Ogden mountains reportedly had snapped trees and vegetation littered in the debris. While these made the headlines, ski area control efforts resulted in many slides up to and just over 2’ deep in wind drifted terrain.
