TUCKERMAN AND HUNTINGTON RAVINES HAVE MODERATE
AVALANCHE DANGER. Natural avalanches are unlikely
and human triggered avalanches are possible. There
may be areas of unstable slab on steep terrain.
With yesterdays new snow and west winds the ravines
have picked up some new slab snow. The new snow
does not seem to be confined to any particular areas
in the ravines, but is widespread. You will need
to use your avalanche skills today.
It looks like we will get some rain or snow later
today, and if and when that happens the avalanche
danger can increase. Watch for changing conditions.
ICE DAM development should be one of the primary
hazards for ice climbers in the Ravines. Be cautious
for hydrolic pressure and ice dams in commonly found
areas such as over the top of bulges and steep colums.
THE LION'S HEAD WINTER ROUTE IS OPEN. Follow the
orange Lion Head signs off of the Tuckerman Ravine
trail about 1.75 miles up from Pinkham. Use caution
on the trail as there are areas where the rocks
are showing. Please stay on route to minimize climber
impacts to the area. 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 essential.
The ski trail has full coverage but is quite thin,
so watch for an occasional rock sticking through.
Expect a hard frozen trail under a veneer of snow.
There are sections of water ice that maybe hidden,
especially on the lower third of the trail.
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.
