MOUNT WASHINGTON, N.H. -- The U.S. Forest service Monday posted an avalanche advisory for Tuckerman Ravine on New Hampshire's Mount Washington.
The ravine is a popular spring skiing destination.
The forest service said that a waterfall has left a large hole in the snowpack, making for a hazard that cannot be seen from above.
The service said that a person falling into the hole would be swept under the snowpack.
CREVASSES CAN BE FOUND THROUGHOUT ALL AREAS OF THE RAVINE AND WILL CONTINUE TO OPEN IN THE COMING DAYS. From above it is impossible to tell where any of the crevasses are so hiking up what you plan on skiing is recommended so you can see what you're in for on the way down. Over the past 2 weeks multiple people have gone into these slots. Be very aware of this growing hazard throughout the ravine. The main waterfall that is climber's left of the Lip has opened up a large hole in the snowpack. This poses a significant hazard and it is difficult to see from above. If a person were to fall into it they would be swept underneath the snowpack by the river. More water is flowing which has increased the size of the waterfall and the extent of undermining throughout the ravine. We will be watching the Lip area closely and anticipate closing it soon as well as the Tuckerman Ravine trail through the Ravine. Expect to use alternative routes in the near future as crevasses become larger and increase in numbers.
When leaving the Bowl please take your skis or snowboard off and walk down the trail. The trip down the Cutler River and Little Headwall is fraught with hazards and not recommended. Open water, large deep holes, crevasses and unstable snow bridges all exist between the Bowl and Hermit Lake so use common sense and avoid a catastrophe.
