Blowing snow and low visibility in Tux

By Joe Soccio | MWAC

Date of Observation: January 7, 2020  10:00 AM
Location of Observation: Tux’s Trail near little headwall

Fresh low-density snow from the afternoon of 1/6 was being transported by strong west winds. New snow was undisturbed below tree line. Near treeline, winds began to scour and load some areas of the terrain. Visibility was minimal at higher elevations.


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.
