TUCKERMAN RAVINE HAS CONSIDERABLE AND MODERATE
AVALANCHE DANGER. Hillmans, the Lower Snowfields,
the Little Headwall, Left Gully, and Right Gully
have Moderate (Modéré) avalanche danger. Natural avalanches
are unlikely and human triggered avalanches are
possible. Use caution in stepper terrain. All other
areas have Considerable (Considérable) avalanche danger. Natural
avalanches are possible and human triggered avalanches
are probable. Be increasingly cautious in steeper
terrain.
HUNTINGTON RAVINE HAS CONSIDERABLE AVALANCHE DANGER.
Natural avalanches are possible and human triggered
avalanches are probable. Be increasingly cautious
in steeper terrain.
The summit received 5 inches (13 cms) of new snow
and we picked up 10 inches (25 cms) here at Hermit
Lake. So those of you that have bets that winter
has ended you should get ready to make your payouts,
even if it's just a cup of coffee. Precipatation
began yesterday around midday with winds out of
the South. The dominant snow period saw winds from
the S and SW around 40-45 mph (65-72 kph). This
loaded Northerly aspects. Very late last night winds
began to shift through the W to NW, where it currently
sits. So at least some loading occured on all aspects
in the Ravines. Evidence of avalanche activity was
seen in the Lower Snowfields and the Bowl. I was
a bit suprised to see some areas as wind affected
as they were, as well as seeing the old ice crust
in places. Winds should increase later as a cold
front approaches sending us back into winter temperatures
for this first week of Spring. As this occurs expect
snow to be picked up from above treeline and redeposited
in avalanche start zones in the Ravines. Also watch
for snow showers to bring in additional accumilation
as well.
We had a couple close calls with dogs and one serious
ski edge injury Sunday afternoon. As spring approaches
the Ravine will see more and more of our canine
friends. Realize this can be a very dangerous place
for your dog and you need to be responsible for
their safety.
THE LION'S HEAD WINTER ROUTE IS OPEN. However it
is deteriorating quickly due to poor snow coverage
and warm weather. This new snow should help, but
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 new powder snow covering a very
hard and often icy base. There may be ice flows
and rocks hiding under the powder. As skiers and
riders begin scrapping off the last 2 days of snow
use extra caution for these hidden hazards.
PLEASE REMEMBER:
Any new precipitation may increase the avalanche
danger, this includes wind transported snow.
Obtain latest weather forecast before starting out.

This bulletin expires today at midnight and the
next avalanche bulletin will be issued tomorrow.
