This was on Crowfoot mountain for the annual crab fest March 23rd. I was filming while sidehilling above the hole you see at 0:39 and looped back around to go up the ravine when Jevon noticed the hole and ditched his sled to avoid lawn darting it into the hole. However, he landed in the hole and a 5x5 slab slid over top of him, he was completely buried with only one hand above the surface. Thankfully all was well!
