Huntington Ravine has Considerable avalanche danger. Natural avalanches are possible and human triggered avalanches are probable. Unstable slabs are probable in steep terrain. Be increasingly cautious in steeper terrain.

After a great day of loading and avalanches yesterday, the snowpack is trying to adjust to the abrupt changes it has endured over the past 48 hours. Currently low level clouds are obstructing our view into the Ravines, however, we have been able to observe some interesting things. Huntington Ravine still has snow swirling around and it appears that the gullies did not get scoured by wind leaving unstable slabs in place. We can tell avalanche activity occurred in Damnation, O'Dell, maybe South and below the Yale Slab. Tuckerman Ravine is still completely obscured by clouds but I can see that the Duchess had some activity in it. As the day progresses we expect the clouds to lift and look forward to a complete investigation of yesterday's events. There are two concerns for travelers in avalanche terrain today. The first is any gully or snowfield that avalanched and filled back in with new slab. At this time it appears that we have plenty of these around. The second concern is any gully that didn't avalanche yet and has larger slabs that are ready to go. You may not be able to decipher the two but it doesn't matter. Both are problematic and you need to realize that instabilities may be found in all forecast areas. Winds have subsided since yesterday and loading isn't aggressively occurring as it was yesterday. This makes us more concerned with the probability of human triggered avalanches than with the possibility of natural avalanches. That means we are concerned about you triggering an avalanche if you choose to play in avalanche terrain today.

THE LION HEAD SUMMER TRAIL IS NOW CLOSED DUE TO THE AVALANCHE PRONE SLOPES JUST BELOW TREELINE. THE LION HEAD WINTER ROUTE IS OPEN. Mountaineering skills and equipment are required for safe travel on this route.

The Sherburne Ski trail has top to bottom coverage though it is quite thin in places. Expect rocks and abrupt waterbars along the way.

As always, this advisory is one more tool to help you make your own decisions in avalanche terrain. It should be used along with your own snow stability assessments, knowledge of safe travel techniques, skill in reading mountain weather's effect on the snowpack, and avalanche rescue. To improve these skills take an avalanche course. We have all the avalanche courses offered in and around the Mt. Washington Valley this winter on our website, tuckerman.org.
