Snowpack

Southern aspects at lower elevation, consisted of facets to the ground in shallow areas and breakable 1-2 inch think breakable solar crusts. Upper elevation S slope housed surface facets on supportable base, stiff wind board, and boiler plate solar crusts. On N and NW aspects we skied a lot of soft wind blown snow, stiff wind board, Shallow areas were again entirely sugar snow. No formalized profiles dug. Signs of instability: Multiple whumphs and larger settlements on S facing lower elevation slope where thin snow pack often rested on top of barried willows (between 9,600-10,200). One smaller settlement noticed around 11,800 in a NW skin track. One recent wet slide was also observed coming out of rock bands on WSC Peak.
