WE ARE NOW POSTING BULLETINS ON AN AS NEEDED BASIS AS CONDITIONS CHANGE SO YOU MAY NOT SEE A NEW BULLETIN EVERY DAY. WE ARE THROUGH FORECASTING FOR HUNTINGTON RAVINE FOR THE SEASON. YOU WILL NEED DO YOUR OWN STABILITY ASSESSMENT WHEN ENTERING THE AREA. THERE WILL BE A DANGER OF FALLING ICE (GLACE EN CHUTE) FOR THE REST OF THE SPRING.

TUCKERMAN RAVINE HAS MODERATE AVALANCHE DANGER. Natural avalanches are unlikely and human triggered avalanches are possible on steep snow covered open slopes and gullies. Use caution

in steeper terrain.

You should also anticipate avalanche danger on the snowfield traverse at treeline on the LION HEAD SUMMER TRAIL. This area has a similair aspect as Tuckerman so expect loading into this lee location. You need to have good avalanche assessment skills to travel through this area safely.

The summit of Mt. Washington received 4 inches (10 cm) of low density 5% snow over the past 24 hours with winds from practically all points on the compass. Winds began from the SW and wrapped through the S, SE, to E before a rapid shift to our prevailing westerlies. Then early this morning winds began moving N to the current NNW at 20 mph. Winds are forecasted to increase today to 20-40mph. As winds increase you should expect last nights 5% snow to load easily into lee areas. Snow showers are also expected so anticipate a rising avalanche danger. New snow may also hide hazards into the weekend. So be very cautious for a veneer of snow over crevasses and rocks.

The Lip is now very narrow with many crevasses in the area. It will be melting out soon so watch for this area to be closed within the next week. The Little Headwall is now a raging torrent and the waterfall on the Lip is now wide open. Stay clear of these and other deep crevasses that have formed in the Ravine. Falling into some of these would be very unfortunate resulting in a high liklihood for grim consequences. Many areas are now undermined so be prepared for collapasing snow beneath you. CLIMB UP WHAT YOU PLAN ON COMING DOWN TO AVOID ANY SURPRISES. PLEASE take off your skis to walk 40 yards rather than ski over fragile alpine vegetation when leaving areas like Hillmans Highway and the Lower Snowfields. Many of those little trees are over 100 years old.

BE AWARE OF FALLING ICE (GLACE EN CHUTE)! Each year over 1000 tons of ice forms on the headwall in Tuckerman Ravine and the gullies of Huntington Ravine. In the spring it all comes down, often in pieces larger than cars. Many folks have been injured and even killed by falling ice (glace en chute). Pay attention to where you are, do not linger under ice. Have a plan in mind about what you will do if ice comes down. Station yourself near a large rock to duck behind in the event of ice fall. BE ICE SMART!

THE LION HEAD SUMMER TRAIL IS NOW OPEN. Realize the summer trail still has large steep snow traverses. A fall here may see you going over a cliff band so you will need crampons and an ice axe to travel safely in this area. These snowfields may also be an excellent sliding surface for avalanche activity in the event we get more snow. This is always a possibility during April and May at 5000 ft. MOUNTAINEERING BOOTS, CRAMPONS, AND AN ICE AXE ARE NEEDED!

THE JOHN SHERBURNE SKI TRAIL IS NOW CLOSED TO ALL USE. Just because you see snow in back of the rope it is only continious for the first 200 feet. After that you are in mud most of the time. This is the truth. TO PREVENT EROSION TO THE SKI TRAIL PLEASE USE THE TUCKERMAN RAVINE TRAIL FOR HIKING BOTH UP AND DOWN FROM PINKHAM NOTCH. There is no skiing or riding allowed on the Tuckerman ravine trail.

 
PLEASE REMEMBER:
 
• Any new precipitation may increase the avalanche danger, this includes wind transported snow.
 
• Obtain latest weather forecast before starting out.
 
• For more information, contact the U.S. Forest Service Snow Rangers: AMC at Pinkham Notch Visitor Center or Hermit Lake Shelters.
 
• This bulletin will be updated on an as needed basis as conditions change.
