More detailed information about the snowpack: 

 

Toured up to Red Cone Bowl from end of Lake Mary road. No signs of instability today on route. Minor warming on east facing slope at 9,500', top 8 cm were slightly moist with dry cold snow underneath. Small rollerballs noted on slopes below cliff bands and trees, on all aspects including north at 10,000' (see attached photo). North facing rollerballs likely due to greenhouse effect from cloud cover yesterday. Evidence of widespread avalancheing during the last storm. 

Dug snow pit just below ridgeline on windloaded east facing slope at 10,150'. No concerning test results, ECTN due to slight density change, 38 cm down. See attached profile. Minor crusts near surface found. 

Suprisingly very minor warming on solar aspects today probably due to thin high cloud cover. No recent rollerballs today. Significant cornices on North facing slopes. Variable ski quality throughout.
