Moab Avalanche Advisory

Forecaster: Dave Medara

SPECIAL ANNOUNCEMENT

The LSAC still has room for more folks in both our Level 1 (Jan 28-30) and our Level 2 (Feb 3-6) Avalanche Courses. These courses are provided through the American Institute for Avalanche Research and Education who offer an excellent curriculum and teaching methods. They're also inexpensive!


BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.
(click HERE for tomorrow's danger rating)


Danger Rose Tutorial

An inch or two of new snow overnight in the La Sals, trace in the Abajos.

The BOTTOM LINE for today in the Abajo and La Sal Mountains is an avalanche danger of MODERATE or LEVEL 2.

Skiing and Riding conditions are excellent E-NE-NW facing slopes and in flat areas.


CURRENT CONDITIONS

It looks like an inch or two of new snow has fallen overnight at the Geyser Pass Trailhead since about 1 AM last night. Sun has made SE-S- SW facing slopes pretty crusty and winds have also damaged snow quality up high. Nonetheless great skiing and riding conditions can still be found on low and mid elevation shady side slopes.

Last Wednesday we took a tour down to the Abajos for a bit of a change up. We found some fantastic NE. facing snow, very convenient access, and the lovely feature of not having to put your skins back on to get back to the parking lot after skiing like you do with so many tours in the La Sals. We found about 50 inches of snow at about 10,000 ft over there. Try it out!

We have about 55 inches of snow at the Gold Basin Study Plot, and 32 inches at the La Sal Snotel. We are 133% of normal water in the La Sals and 201% of normal in the Abajos.

The Geyser Pass road was plowed on 1/11/11. It is buffed. Access to the old Blue Mountain Ski area in the Abajos has been plowed to the base of the hill - very convenient!

Almost all of the La Sal Nordic system has been groomed by Matt Hebbard. There are probably 12 miles or so of groomed trails up there and we've tried to add some extra terrain at lower elevations near the trailhead so take advantage folks! Maps are available at the Geyser Pass TH Kiosk.


RECENT ACTIVITY

some wet stuff from the last couple of days.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 48 hours.

In both the La Sals and the Abajos, it seems that as you go from South to North, the snowpack gets shallower, and funkier. With our big storms coming in on a South flow, this isn't too surprising. There is some very strong, deep snow in the southern parts of both ranges, but as we move north, weaker, highly layered snowpack structures continue to be identified in the mountains of SE Utah. With both surface hoar and faceted crystals buried in the snowpack between individual storm layers, the snowpack has serious structural issues. In short, you just can't trust it.

Cracking and collapsing are STILL being felt in the Backcountry. Snowpit tests do not inspire confidence. This means heads up on steep E-NE-NW facing slopes in areas with a shallower snowpack. This shallow snowpack zone DOES include Gold Basin. We backed off a steep slope in the Abajos on Wed., opting for safer, less steep slopes out of an adjacent slide path. It may still be possible to trigger an avalanche into old snow in some places, especially with the added weight last night's snow and whatever we might pick up this morning. We are keeping the avalanche danger rating at MODERATE or LEVEL 2. While unlikely, Human Triggered Avalanches remain a possibility.

GENERAL ANNOUNCEMENTS

We will update this message Saturday morning.

The Utah Avalanche Center has a limited number of discount lift tickets available for Brian Head Ski Resort. Follow this link for more information: http://www.backcountry.com/utah-avalanche-center

The LSAC will be offering 2 avalanche classes this year. Our yearly Level 1 class will be held January 28, 29 and 30 of this winter season. The level 1 class focuses on avalanche phenomena, recognition and management of terrain where you might encounter these beasts and basic rescue.

This season, if we can pick up 6 participants, we are also hoping to do a Level 2 class. Tentative dates for the class are February 3-6. It is a 4-day class reviewing the basics covered in level 1, then carrying the subject matter further, exploring snowpack formation, crystal analysis, climactic effects and advanced rescue.

Call 435-636-3363 and speak to Dave or Max for more information or to sign up for one of the classes.
