Just enough snow to make for easy hiking. Small knee deep drifts in sheltered locations.

Boring. Nothing. Need more snow and ice for crampons on LH Summer Route – dicey ascent with microspikes. See my Facebook spray for more pics. Very few Massholes observations outside of me.

Tuckerman Ravine from Hermit Lake

November 9, 2019
By Sebastian Dawson – AMC

It’s starting to look like winter at Tuckerman Ravine. There is about 4″ of super light, fluffy snow on the trail with running water in the ravine headwall. Low wind and good visibility brought a decent number of visitors today, and low temps enabled . . .

We had just reached the bowl after hiking up to snowboard.The boys set off to get a quick run in while i had set my pack down to eat a snack and take a rest.I sat on a rock while watching them off to my right when I heard a loud thunder crack sound.I . . .

Great Gulf conditions

The snow is holding on pretty well in the Great Gulf, better than expected. I dropped down Spacewalk, which was still very filled in with perfect corn and minimal sluff. The Airplane Gully runout still goes to floor of the ravine. I booted up Rog’s . . .

Rock Slide from Lion’s Head

By Jason Cascone – New York City Fire Dept

On May 2, 2019, at approximately 1322 hours, my hiking partner and I experienced a massive rock slide while hiking with our skis along the Tuckerman Ravine Trail. The rock slide lasted for—we estimate—at least thirty seconds. It was long enough for . . .

Shrinking Snowpack

On April 11, the Hermit Lake Snow Plot had 200cm of snow on the ground. On May 1 the total has melted to 138cm. The difference is striking in Tuckerman Ravine.

Tuckerman Ravine April 25

By Jeffrey Fongemie – Mount Washington Avalanche Center

We’ve lost significant amounts of snow with the warm weather this week. Glide cracks, waterfall holes and undermined snow now exist. Large chunk (refrigerator size) of ice on floor of ravine from Center Bowl ice cliffs. Active waterfall in lip area.

Heard a scraping sound thought it was a skier, but it was this huge ice boulder rolling down the bowl. A lot of other smaller debris observed at base of bowl

Wet Loose slide in Left Gully, Tuckerman’s Ravine

By Will Synnott – Dartmouth Winter Sports Club

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 . . .

ABOUT THESE OBSERVATIONS

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.
