Appears to be a natural. We didn’t get high enough to get a close look as the surface was pencil hard in exposed terrain. Some soft turns were found in the woods though. Flume and Silver Cascade both had pockets of 4F however those are few and far . . .

Natural avalanche occurred during the February 25 storm. 8.5″ snow & sustained high winds.
Crown estimated to be 3′ tall, 200 feet wide and very low with respect to the whole slope of Raymond’s Cataract.
Natural avalanche occurred during the February 25 storm. Heavily refilled and eroded. Visible crown line 2″. The shape of the crown suggests that it may have extended to lookers left under Dutchess and also some signs of it to lookers right around . . .
