"Around 2 PM, ~ 43  degrees, NNE facing, 9440', 5 turns in, the slope cracked out above me, guessing 1.5 feet deep, 50 to 70 feet wide, and carried me 4 or 500 feet over a rock band. I seem to have hit the rocks with my board (judging from the 6" core shot and bent edge, which I did not feel), tumbled over the rock band, cushioned by the debris, then felt the harder bed surface in the chute, tried to dig in an edge, got my head out and got oriented, more heelside edge contact, gradually slowed down as the debris washed over my shoulders and past me. The slide  ran another 4 or 500 feet. Bruised heels, a little beat up, but basically unhurt."
