Avalanche Observations in Tuckerman Ravine

By Helon Hoffer | Mount Washington Avalanche Center

Date of Observation: January 4, 2019  2:00 PM
Location of Observation: Tuckerman Ravine

On touring into Tuckerman today, we noted the following activity:
SS-N-R1-D1.5 in Center Bowl of Tuckerman. This likely occurred 1/3/18. We think so by the amount or reloading that took place. This may have been triggered by very small dry-loose avalanches (sluffs) that were evident above the crown.
SS-N in the very high point of Chicken Rock Gully (where Sluice turns to skier’s right and tucks under the Lip). The crown that was visible was ~5m wide. We were unable to discern much more due to our location in the Bowl.

Most locations in the Tuckerman Headwall displayed signs of sluffing, including active sluffing in the Sluice while we were in the Ravine.


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.

Your observations are valuable to an accurate forecast! We welcome observations from everyone. You don’t need to be an avalanche professional to submit helpful observations, just be as detailed and accurate as you can.
