TUCKERMAN RAVINE HAS CONSIDERABLE AVALANCHE DANGER.
Natural avalanches are possible and human triggered
avalanches are probable. There are unstable slabs
on most steeper slopes. Use extra caution in steep
terrain.
THE LITTLE HEADWALL HAS MODERATE AVALANCHE DANGER.
Tuckerman's has picked up another two and a half
inches with high winds and considerable drifting.
Some areas are scoured, but most slopes have received
new wind slab. The depth and area of these wind
slab areas vary, and are difficult to determine
with poor visibility due to fog and blowing snow.
Good avalanche skills are needed if you go on the
slopes today. Don't forget to travel at least in
pairs and carry avalanche transceivers, shovels,
and folding probes.
HUNTINGTON RAVINE HAS MODERATE AVALANCHE DANGER.
Natural avalanches are unlikely and human triggered
avalanches are possible. There is considerable drifting
in wind protected areas. This new wind slab has
easy shears. The new snow has good adhesion to yesterdays
wet snow.
Expect cold and windy conditions today with summit
temperatures expected to be well below freezing.
We have reached the high temperatures of the day
already. Be prepared for full winter conditions
above treeline.
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 an absolute necessity.
ON SATURDAY NIGHT WE RESCUED 4 INDIVIDUALS, ONE
OF WHICH WAS INJURED, DUE TO THE LACK OF APPROPRIATE
EQUIPMENT. MOUNTAINEERING BOOTS, CRAMPONS (not step
ins or sidewalk ice knubs), AND AN ICE AXE ARE NEEDED!!
BE AWARE OF FALLING ICE! Due to it being both winter
and spring up here this hazard will come and go
with warm and cold temperatures. When it's warm
and sunny this hazard will increase and when it's
10 degrees F and blowing at 100 mph the hazard will
subside. Each year over 1000 tons of ice forms on
the headwall in Tuckerman 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 John Sherburne ski trail has good cover with
the thinner snow on the bottom. Watch for rocks
pokeing thru the snow as melting continues.
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 expires today at midnight and the
next avalanche bulletin will be issued tomorrow.
