Avalanche Details

Remote triggered by first skier on the slope. Release point was ~20 feet right of the ski line. Slope angle was ~30 degrees where the skier was but the angle was closer to 40 degrees where it released. Seems likely that release point was in shallower snow by some rocks. No one was caught by this slide. Small avalanche but would still have been big enough to knock a person over.
