Avalanche Sierra Buttes

We remote triggered a 40 foot by 50 foot 8 inch deep wind slab about 40 feet below our skin track while going up. So we turned back to get to a spot to transition to ski down. I triggered a wind slab and sluff that knocked me over and drug me about  75 feet and buried me up to my waist. I was not hurt and self extracted. The crown at the top was about 4 inches tall but it was 1 to 2 feet deep by my tracks where I triggered it. The full path was about 50 feet wide and over 100 feet long
