TUCKERMAN AND HUNTINGTON RAVINES HAVE LOW (FAIBLE) AVALANCHE
DANGER. Natural avalanches are very unlikely and
human triggered avalanches are unlikely except in
isolated pockets on steep snow covered open slopes
and gullies. Normal caution is advised.
Rain showers are forecasted for today so be prepared
for an increased hazard of undermined snow, crevasses,
and FALLING ICE (GLACE EN CHUTE). We put a few pictures on the website
Thursday afternoon. Some open holes are visible
in these shots which will give you an idea where
some hazards are located. I

believe at this point
we will need quite a bit of rain to increase the
avalanche danger rating from Low. However, be prepared
for the possibility of wet point release sluffing
in pockets and water running under the snow to blowout
areas of the snow pack. The most likely areas to
blowout are on the main waterfall near the Lip and
the Little Headwall, but realize this hazard exists
in other locations as well.
Crevasses are beginning to form on the Headwall.
These can become very deep with a couple plunging
80 feet. The Little Headwall has a very large hole
from Tuesday's rain where the river is exposed.
Extreme caution should be used when approaching
and skiing around this area. Walking down the Tuckerman
Ravine trail is a good alternative to get from the
Bowl to the Hermit Lake area. This also helps preserve
very old dwarfed trees called krumholtz. PLEASE
take off your skis to walk 40 yards rather than
ski over fragile alpine vegetation. There is undermined
snow on The Lip. Stay close to climbers right as
the waterfall is on the left and it may be covered
with a skim coat of snow. Remember,CLIMB UP WHAT
YOU PLAN ON COMING DOWN TO AVOID ANY SURPRISES
BE AWARE OF FALLING ICE (GLACE EN CHUTE)! With today's rain and
warm weather in the 70's predicted through the week
we are absolutely in ice fall season. 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'S HEAD WINTER ROUTE IS OPEN. Please stay
on route to minimize climber impacts to the area.
This is critical to keeping the trail open and protecting
the resource. Consider it good practice to move
slow and thoughtfully with crampons on rock. This
is a difficult steep route so crampons, ice axe,
and mountaineering skills are a necessity. MOUNTAINEERING
BOOTS, CRAMPONS (not step ins or sidewalk ice knubs),
AND AN ICE AXE ARE NEEDED!!
The John Sherburne ski trail has good cover on the
upper portions with thin snow and bare spots on
the lower half. Patches of water ice are scattered
from place to place for the full length of the trail.
These areas are at times only visible once you are
on top of them, so ski slowly to avoid dangerous
surprises. As of yesterday morning skiing to Pinkham
was still possible, but we did loose quite a bit
of coverage in the afternoon heat. In addition,
today's rain will continue to eat away at the ski
trail's snow cover. So be prepared to walk any day
now and please cross over to the Tuckerman Ravine
hiking trail and walk the short distance to Pinkham.
This will help keep the ski trail from eroding.
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 expires today at midnight and the
next avalanche bulletin will be issued tomorrow.
