Mammoth Rock Bowl
Wednesday, December 23, 2015 - 8:00pm
Naturaly trigger avalanche during the storm / heavy winds likely during the night of Dec 23rd. Hard wind slab, 2.5-6' crown that wrapped around most of bowl. Released just below ridge top at convexity. Broke several small trees in run-out zone. Hard slab, pencil hardness, ran on pencil hardness layer with no obvious weak layer in between. Did NOT run to ground.
Cold day, -10 deg celsius air temp. Calm winds :-). Scattered clouds.
