General Comments

These photos will likely accompany Nallis' Obs.

Heard about this avalanche from the Sundance Ski Patrol on Monday, April 11th. It's likely that it ran sometime during the storm on either 4/9 or early morning 4/10 from a natural cornice drop. HS-N-R3-D4-O running on facets above the upper layer of the MLK crust from 1/16. Crown was 6'+ deep in places. A second rain crust still exists below the bed surface with 122cm of snow remaining to the ground. This is another repeater that has avalanched 3 times already this season.
