We noticed this large avalanche from a distance today above Smith and Morehouse reservoir. East aspect at 9800' east of Shingle Mill Flats. All dimensions and timing are my best estimates. The depth looks to range from 2'-4' deep, 200' wide and 800' vertical. It likely released sometime toward the end of the last storm, on 3/15. No tracks nearby so likely SS-N-R2,D2.5-I.
