Observations

NW face on hangover hill held a top layer of unconsolidated facets likely caused by warming cycles over the last week
The greater danger is 1.5” below those surface. The stronger layer was sandwiched in between and very large layer of HUGE feathery facets approximately 2” in length and 1.5” in depth.
These feathers were noticed on the surface of the snow a week prior to the above observations at hangover hill (photo attached)
Both of these layers near the surface provide substantial concern for persistent weak layers as the season progresses
