Harvey Pass Avalanche

Good early season conditions at Harvey with ~30cm depth snow. On the skin up, a crown was observed in one of the chutes off the front face of the ridge. Snow at the top of the ridge felt uniform with no obvious crusts. Watched a group of 4 ride Curveball without issues. Chose to ride the chute to the skier's right of Curveball. Skier attempted a ski cut at the top of the run with no effect-however the skier was not experienced with ski cutting. Skier began to ride, and triggered a size 1-1.5 avalanche on second turn. Skier was knocked down by the avalanche and carried in a sitting position about 50m. Skiers' torso remained above the snow, and they were able to dig themself out when the avalanche stopped. Skier was able to traverse left into Curveball chute and skied out from there.
