Avalanche Details

Was skiing back down Marmot near the uptrack. Was staying slightly towards skiers right (west) to avoid shallow/rocky areas for the first couple of turns, before cutting back left. Caused a larger, deeper collapse, that triggered the avalanche. Snow fractured at skiers feet, or slightly below. It propagated out into a steeper wind loaded pocket to skiers right and down the slope.
