Kernpunkte

A MODERATE avalanche danger exists on slopes that face W-N-SE near treeline and above where slabs of wind drifted snow exist on top of a weak, fragile snowpack. Human triggered avalanches are possible on these slopes. Slopes that face SW-S and below treeline terrain offers a LOW danger.

It's still low tide out there and rocks, stumps, and deadfall are lurking just beneath the surface. A ride in even a small avalanche in these low snow conditions would be rugged.

    Southerly winds have created fresh slabs of wind drifted snow on slopes facing W through N through SE. Wind slabs are recognizable by their smooth, rounded, "pillowy" appearance and they may sound hollow underneath. Cracking is a sign of instability. Look for unstable areas of wind drifted snow on the the leeward sides of ridge crests and terrain features such as rock outcroppings, sub ridges, and gully walls. Due to higher wind speeds, they may also exist further down slope than you expect. Avoid steep slopes that have recent deposits of wind drifted snow.

    The photos below were taken by Dave Garcia earlier this week. Note the pillowy nature of recent wind drifting as well as down slope loading.

Additional Info

This snow profile shows our very weak snowpack that was just buried by seven inches of snow.

Even if you're not planning to get onto the snow, it's never too early to start thinking about avalanches. A few things to consider doing:

  • Sign up for an avalanche class.
  • Take the all-new online avalanche courses the UAC built for Know Before You Go or take other online courses listed on the KBYG website (Develop skills -> Online Learning).
  • Get your avalanche rescue gear ready for winter. Put fresh batteries in your transceiver and update the firmware. Inspect your shovel and probe. Get your airbag backpack ready by possibly doing a test deployment and update the firmware if it is an electric version.

Road Conditions: Grand County has not yet begun plowing the road to Geyser Pass Trailhead. The road is hard-packed snow and slick in places. Good tires and all wheel drive are recommended.

Grooming: The Geyser Pass Road above the winter trailhead closes on Dec 15. Grooming will commence after that.

The story continues to be the wind. Southerly winds have been pretty relentless for the past 36 hours averaging 25-30 mph, with gusts as high as 47 mph on ridge tops. Today, we'll continue to see cloudy skies and strong winds as a powerful storm moves through to the north. Unfortunately for us, we're going to see a lot of huff and puff and not much fluff wiht a few scattered flurries possible this morning with maybe an inch or two of accumulation. Cloudy and breezy conditions persist through Saturday with the next system moving in on Sun- Mon. This storm doesn't look to be much of a producer for us either. An unsettled pattern remains in place through next week, we'll see if anything shapes up.

Southerly winds are continuing to drift Monday's seven inches of low density snow, forming unstable slabs on leeward slopes near and above treeline. Alternately, windward surfaces are scoured, crusted, and sculpted. Complicating the picture are older wind slabs that formed earlier this week, all of which are sitting on top of a foundation of weak, sugary, faceted snow. The bottom line is that the snowpack isn't shaping up all that well and we will soon be facing a persistent weak layer problem. It's also still low tide out there with lots of rocks, stumps, and logs lurking about. It's just not quite game on yet, we need another foot or so of snow.

If you are getting up into the mountains please submit an observation and let us know what you are seeing!
