Wet loose avalanche activity

By Ryan Matz | MWAC Forecaster

Date of Observation: February 4, 2019  2:00 PM
Location of Observation: South Gully, Odell Gully, Hillman’s Highway

Wet loose debris observed in South and Odell Gullies of Huntington Ravine and Hillman’s Highway. Particularly in South and Odell, these were relatively debris piles for sluffing but still D1 so likely unable to bury a person. All appeared to be skier initiated, though South may have initiated naturally.
Photo of South and Odell also shows distinctly grey January 25 crust in the foreground. This crust softened but remained supportable in Huntington yesterday.


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.
