Crested Butte Zone

CB Avalanche Center2014-15 Observations

Name: Evan Ross
Location: Mt Emmons
Date of Observation: 12/26/2014
Aspect: South East, South
Elevation: 9,000 to 11,300

Weather: Mostly cloudy, a few S-1 snow squalls, calm wind at BTL and NTL elevations.

Snowpack: Enough solar today for a soft and thin sun crust to form on south slopes over 30 degrees. At 11, 300ft, HS 110, 12/13 interface was down 60cm. Sitting on top of that 12/13 sun crust interface was 10cm of F hard snow, likely NSF. Above this poor structure was the solstice storm and more recent storm events with a slab at its base of 1f to F at the surface. A very quick and singular test was CT14 RP on the NSF. No collapsing or other obvious signs to instability while traveling on these slopes up to 32 degrees. At 11,700ft and just above treeline on a SE ridge, there was no recent signs of wind transported snow in the last 24hr.
