Tuckerman Ravine Snowpack

By Jeff Fongemie | Mount Washington Avalanche Center

Date of Observation: March 27, 2019  1:30 PM
Location of Observation: Tuckerman Ravine

Good skiing conditions today in Tuckerman Ravine.

Tuckerman Right Side had full sun today allowing the top two centimeters of the snowpack to become moist. Little to no wind.

Many hand sheer tests with Moderate and Hard results. ECT tests: ECTN22 & ECTX. Lip, Sluice, Right, Lobster Claw, Right of Right, Left, & Dutchess were all skied today with no signs of instability.

Tuckerman Left Side looked to have more remaining soft slab, though mixed with scoured areas.

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.
