Toured up Colorado Mtn. to the first of the E-NE facing gullies at about 2,700’, dug a very quick pit and skied incredibly good snow all the way back to the road.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.
Weather

Substantially warmer in the Summit Lake area Sunday morning / midday than any time since Friday afternoon at least. -3.5C at 2,700’ at 2:30p
Sky: Overcast
Precip: none
Winds: mostly light, occasionally gusting moderate from N/NE

Snow surface

Surface hoar growing through all elevation bands up to 2,700’. Touring partners reported a change to wind effected surface snow just a little bit higher than where I stopped to dig, probably 2,800’.
Soft dry powder all the way back to the road.

Snowpack

I observed a very similar snowpack to Moderow from Dec. 30th. I dug in a slightly deeper spot, it was HS 130-140cm in the area of my pit.
Key features were pencil hard melt crust 90cm down from surface, as well as band of what I’m assuming is buried surface hoar 25cm deep.
Performed two instability tests (very quickly) - CTN and ECTX.
