TUCKERMAN RAVINE HAS CONSIDERABLE, MODERATE, AND
LOW AVALANCHE DANGER. The Lip and the Northern
side of the ravine has Considerable avalanche danger.
Natural avalanches are possible and human triggered
avalanches are probable. Be increasingly cautious
in steeper terrain. The Lower Snowfields, Hillmans
Highway, Left Gully, and Right Gully all have Moderate (Modéré)
avalanche danger. Natural avalanches are unlikely
and human triggered avalanches are possible. Use
caution is steeper terrain. The Little Headwall
has Low avalanche danger. Human triggered avalanches
are unlikely except in isolated pockets. Use normal
caution.
HUNTINGTON RAVINE HAS BOTH COSIDERABLE AND MODERATE
AVALANCHE DANGER. Central Gully has Considerable
avalanche danger. Natural avalanches are possible
and human triggered avalanches are probable. Be
increasingly cautious in steeper terrain. All other
gullies in Huntington have Moderate (Modéré) avalanche danger.
Natural avalanches are unlikley and human triggered
avalanches are possible. Use caution in steeper
terrain.
Well, another couple of inches overnight has brought
the week's total to approx. 26 inches (65 cm) which
has helped our snow coverage considerably. Picking
precipatation up slowly over the past week with
loading winds has been more benificial than receiving
it all in one big dump. Although we did have a few
large avalanches, we were able to keep snow up in
the gullies rather than a large avalanche cycle
sending debris down into the flats. This helps prolong
gully skiing later in the spring. Another large
avalanche fracture line was visible above Tuckerman
Ravine today. Low visibility has obscured seeing
this area for a couple of days so it is not clear
when this avalanche occured. The Bowl should of
shown more evidence of this debris barreling down
it than was seen this morning. My first reaction
was it occured overnight, but now I'm not so sure.
The fracture line runs from over the Chute, above
Saturday's fracture line, towards the top of the
Headwall ice in the center of the Ravine. Large
rocks which were visible a week ago are buried.
We are coming off of High and Considerable avalanche
ratings over the past few days so I would be cautious
and not push the terrain to hard. Be conservative,
and wait for a bit more consolidation and settlement
before pounding the snow without mercy. You should
have good avalanche experience, excellent route
finding skills, and solid avalanche terrain travel
techniques.
With the return to cold weather after a warm pattern
ICE DAMS should be a concern for ice climbers. Play
it smart when choosing your route.
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.
The ski trail has variable conditions. We have stayed
off of the trail for the past few days to let the
powder hounds have at it. So some large whales and
moguls do exist creating challenging conditions,
but you should have fun.
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.
