Introduction: Good
Morning! This is Max Forgensi with the
USFS Manti-La Sal Avalanche Center with your avalanche and mountain weather
advisory. Today is Saturday, December
11th, 2004 at 7:30 a.m.

General Conditions:
What another beautiful day to get out into the La Sals! Yesterday the temperatures at the Geyser
Pass Trailhead reached into the mid-forties while up on Pre-Laurel Peak the
temperatures stayed just below 20 degrees.
The road is plowed, a wide snowmobile track is set to Geyser Pass and
plenty of powder still hiding on North thru East aspects. Yesterday the sun warmed up all the South
through East aspects, especially at or below treeline. Expect a sun-crust on these aspects in the
morning and the potential for point releases on these aspects as the day warms
up.
Current Conditions: (click location for latest data)
Geyser
Pass Trailhead (9,600’): 30 degrees out with 25”-32” on the ground.
Pre-Laurel
Peak (11,700’): 6:00 am temperature
is 17 degrees, with winds out of the NNE at 2 mph, gusting to 8.
Gold Basin has about 40-46” of settled snow on the ground.
Mountain Weather: (At 10,500’)
Today: Mostly sunny. High near 41. Winds will switch to the SSW at 10 mph, gusting to 20.
Tonight: Clear. Low near 23. Winds will continue out of the SSW at 5-10 mph, gusting to 20.
Sunday: Partly
cloudy. High near 43. Winds will be out of the S at 5-10, gusting
to 20.
Avalanche Conditions:
Yesterday was a really good day to go out and observe the changes
in the snow, and it has on all aspects and elevations. The warm weather has started to let point
releases go on S-W aspects, especially after 12:00. If you start to see point releases or roller balls on the slope
your skiing, it is time to get off of them.
I have two main concerns for today. There are still some consistent
wind-slabs above treeline that could be reactive. An avalanche on the headwall of Red Snow Cirque confirms
that. This natural happened on a NE
aspect on a slope ~40 degrees. Another
area is on steep NW-NE aspects below treeline.
There was a sizeable
avalanche in Gold Basin (2’ crown) that happened sometime yesterday. At least 200 feet wide and running for less
than 100 feet, these pockets are just as dangerous as obvious avalanche
paths. Remember, it takes less than a
dump truck of snow to bury you. For
today, I am going to rate the avalanche danger as MODERATE in these areas and on slopes greater than
35 degrees. A MODERATE danger level means that a natural avalanche
is unlikely, while human-triggered avalanches are still possible. Remember to employ your safe-skiing
techniques at all times, and that your first goal is to return safely home to
your loved ones. The mountains will
always be here.
Nordic and Skate Skiing:
An enjoyable day for you
classic Nordic skiers with just a little bit of new snow to break trail
in. Skate skiing will be compromised
due to the fact the track is not very wide and the new snow.
