CB Avalanche CenterCBAC Observations

Date of Observation: 01/11/2022
Name: Harrison Bosler, Math Alagna and Zach Kinler

Zone: Southeast Mountains
Route Description: Drove to Crested Butte Community School, walked to hillside west of school.

Observed avalanche activity: No
Avalanches:
Weather: Blue skies, strong solar, cold temps remained in the valley floor
Snowpack: HS was 90 to 110 cm on NE aspects in town. Very supportive snowpack with 15 cm boot pen. The 12/6 interface is quite thin making up the bottom few centimeters of the snowpack and is sintering and gaining strength. The snow is strong immediately above and below the 12/23 Melt-freeze crust and does not appear to be an issue here. The 1/6 Graupel layer produced easy CT results and Non-Propagating ECT results as there is little slab on top of it in this shallower snowpack, will keep an eye on this one as slabs grow above. 4 mm surface hoar has formed on the surface and will likely continue to grow especially at these valley bottom locations.
