Huntington Ravine Snowpack

By Helon T Hoffer | Mount Washington Avalanche Center

Date of Observation: February 22, 2019  11:00 AM
Location of Observation: Snowfield between runouts of South Gully and Escape Hatch

See SnowPilot profile for snow structure. We dug down to the February 8 ice crust and did not go further. While our we did see a failure in a thin layer of graupel in the surface slab (CT11), we felt our ECTX was more representative of the snowpack we found.


Snowpack observations are one part of the complex puzzle which is your decision to enter avalanche terrain. Some observations may include stability tests. It’s important to understand that the results of a stability tests are seldom conclusive anywhere, but particularly in snow climates and terrain like ours where the primary driver of instabilities is wind drifted snow. Many stability tests exist and each works best with specific avalanche problem types. Stability test results should never be used alone as an indication that a slope or conditions are safe particularly when more obvious red flags are present. Please use this page as part of your information gathering process, but don’t make decisions based on a single piece of information. A good article that summarizes some of the issues associated with snow and avalanche observations can be found here.

The Mount Washington Avalanche Center cannot verify the quality or accuracy of any observations that come from the general public.
