Wet Loose slide in Left Gully, Tuckerman’s Ravine

By Will Synnott | Dartmouth Winter Sports Club

Date of Observation: April 23, 2019  12:40 PM
Location of Observation: Upper section of left gulley

Second skier to drop set off small (D1 or 1.5) loose wet avalanche on first turns into the gulley. The skier escaped to skiers left without much trouble as the slide picked up speed and continued down the slope for about 100 m before petering out downhill. No other significant avalanche activity observed except for easily manageable sluffing. Thick clouds socked in after we skied out of Left, bringing vis to almost Azeri so we decided to call it a day at that point.


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.
