Compiled from multiple observations-
One observed noted "Large avalanche in the Bunny Ears on Elephant Mtn. Best guess is HS-N-R3/4-D3-O."
Second observer noted: "Skiers left flank appears at a distance to be 8-10' and by the looks of the bed surface I'd guess this was on advanced facets on an early season (late Oct/early Nov) ice crust."
Third observed submitted photos of slide from above.
