Slab broke down to surface hoar that was growing on a buried rock band. Snowboarder didn't realize he triggered it until he was at the bottom of the slope out of the way. Everyone in the party had beacons, shovels, and probes, and knew how to use them, and were aware of potential dangers as listed by the UAC.
