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 FOR THE REST OF
THE SPRING.
TUCKERMAN RAVINE HAS CONSIDERABLE AVALANCHE DANGER.
Natural avalanches are possible and human triggered
avalanches are probable. Unstable slabs are possible
on steep slopes. HILLMANS HIGHWAY AND

THE LOWER
SNOWFIELDS HAVE MODERATE AVALANCHE DANGER. Natural
avalanches are unlikely and human triggered avalanches
are possible. I can see about two thirds of the
way up Hillmans and all of the Lower Snowfields
and although there has been a lot of drifting these
areas are showing a lot of old surface. The top
of Hillmans is a concern as it picks up more snow
and is not visible. If you go on Hillmans, use the
lower two thirds to be safe. If anyone goes higher
than that, go to the side of the gully until that
skier comes down. He could trigger a slide that
could come down the gully. The ravine is in the
fog with snow and blowing snow. Hopefully it will
clear off today and give us a better idea of where
the 6 inches of new snow has been deposited. The
ravine is a collecter of snow with a west wind,
so could have picked up a lot of new wind blown
snow. Use your avalanche skills if you go into the
ravine today.
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! 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. 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.

or Hermit Lake Shelters.
This bulletin will be updated on an as needed basis
as conditions change.
