Introduction:
Good morning, this is Max Forgensi with the WE HAVE ONE SPOT LEFT IN OUR AIARE LEVEL 2 CLASS
WHICH BEGINS THIS FRIDAY EVENING AT 5:00 PM. COME AND JOIN THE FUN! FOR MORE INFORMATION AND TO SIGN UP FOR THIS SPOT CALL US
AT (435) 636-3363. To see past advisories check out the ARCHIVE. To see current conditions go to our WEATHER PAGE. To see photos go to the AVIPHOTOS page. MLAC NEWS: We have started an observer page for
folks to send us their backcountry observations. Report what you see in your
backcountry travels HERE.
Please send us your reports on avalanches, ski conditions, road conditions,
snow pit profiles etc. Thanks! You can also report observations at
435-636-3363 |

General Conditions: We
have been receiving some small doses of snow up in the La Sals for the past
couple days. Although only 2”-4”
of snow has fallen from the trailhead up to Geyser Pass, conditions are
freshening up a bit for this weekend.
There are some supportable sun-crusts buried under this new skiff of
snow on South and West aspects.
Try not to pressure your skis too much on this surface or you will
punch through. On North and East
aspects, we still have a weak winter snow pack. Although the last week of warm pressure has been good for
the upper snow pack, the lower layers are still weak and rotten.
The road to the Geyser Pass trailhead has been graded down low and
plowed up high making for some great driving conditions. The Nordic and Skate skiing
conditions up to Geyser Pass and into Gold Basin will be wonderful
today. Mountain Weather: (At 10,500’) Today: A 20 percent chance of snow before 11am. Partly cloudy, with a high
near 36. South southwest wind around 10 mph, with gusts as high as 20 mph. |

Avalanche Conditions: (Link to the
International Avalanche Danger Scale here) Today we are going to look at two
major factors related to avalanches.
On south and west aspects, crusts near the surface have been forming
faceted crystals below them.
With the new snow on top of the crusts, this layering is failing
easily with the pressure of a skier, and fast. These thin sun-crusts could support you in places and fail
in others. It is not likely for
a natural avalanche to occur on these aspects. On the other side of the avalanche rose and onto your
North and East aspects, it appears that this warm weather has helped
stabilize the upper part of the snow pack. Unfortunately, the lower half of the snow pack is still a
cold faceted mess. In places
that have yet to “flush” out these depth hoar crystals, these slopes are
still suspect for large climax avalanches that no-one would like to take a
ride in. Because both these
areas are not very widespread, the BOTTOM
LINE for today will be an avalanche danger of MODERATE on steep
North-East aspects with the classic slab/weak layer (depth hoar)/bed surface
(ground) with no anchors and pronounced trigger points. Be careful on those South-West
aspects where crust sandwiches are lying about as well. We need your observations! Call
435-636-3363 or use the link near the top of the page to get to the observers
page! Yes, DO IT! Take a look at a snow pit from our
tour on 01/15/06 here.
