Happy New Year!
During the month of December the Tetons received over four feet of new snow. Unfortunately, this new snow is lying on a bed of faceted crystals (unstable snow) located deep in the snowpack. Climbers should be especially careful as they could easily penetrate down to the weaker layers and be the ideal trigger for an avalanche. Good route selection and a thorough understanding of the avalanche conditions are going to be key for a safe and successful ascent.

Please be sure to include the Bridger Teton Avalanche Forecast (http://www.jhavalanche.org) as part of your research when planning your trip. Pay special attention to the Snowpack Summaries section of the forecast as this will provide some crucial information as to how the snowpack in progressing throughout the season. As always, the avalanche forecast does not cover elevations above 10,400 feet.

Bradley, Taggart, Leigh, and Phelps Lakes are frozen over.  Jenny Lake is mostly frozen over with thinner, new, ice closer to Cascade Canyon. Jackson Lake has a large section of open water near the middle and close to the west shore. Most of the lake ice has formed recently, due to the below zero temperatures we have been experiencing and will continue to thicken throughout the winter. Quite often we hear tales of near disastrous lake crossings.  Be mindful to monitor conditions while crossing any of the lakes, spread your group out, and be ready to quickly shed your gear in the event of an unexpected plunge.

Winter is in full swing. Ice is starting to form in the usual places; people have been climbing some known haunts throughout the range, but it will still be a while until some of the longer alpine ice routes are in. Though valley snow depths are still a little thin, you should expect deeper snow at elevations above 7,000 feet. For further information about travelling in avalanche prone terrain throughout the Teton Range, please consult the local avalanche forecast at:  http://jhavalanche.org/
BE ADVISED that this forecast does not cover elevations above 10.400 feet.
Should you decide to venture out into the snowy peaks of the Tetons this winter, please take the time to reflect on how difficult it would be to rescue yourself or someone else if things don't work out in your favor. Research your trip thoroughly, go prepared for the worst, and have a safe trip!

Winter has arrived a little early in the Tetons. A recent storm system has dropped 1-2 feet of snow in the upper elevations above 9,000 feet. With only 4-6 inches of snow below this elevation, travel off trail can be pretty treacherous, especially when attempting to negotiate boulder fields and scree. Ice climbs, including the Black Ice Couloir, are not in at this time. Winter travel in the Teton backcountry is not to be taken lightly. Avalanche conditions change and travelers should have a good sense for travelling in avalanche terrain. Please consult the Bridger Teton Avalanche website at:  http://www.jhavalanche.org/

Recent warm weather has made for great autumn climbing conditions, but don't be lulled into thinking that this could be a long trend. Ice and snow is still lingering in shaded areas above 10,000 feet. Cold mornings and shorter days have not allowed for melting in these areas and any new storms will most likely compound existing winter conditions. This is not a good time of year to attempt long climbs for the first time. Be prepared for rapidly changing weather patterns.

The Jenny Lake Ranger Station is
Backcountry camping permits are required year-round for all overnight trips into the backcountry of Grand Teton National Park. Permits are free and can be obtained year-round at the Craig Thomas Discovery & Visitor Center in Moose and during the summer months at the Colter Bay Visitor Center and Jenny Lake Ranger Station. Detailed information can be found in the links on the right.

All route condition information has been removed from this site for the winter season, however, the HOME PAGE will continue to provide periodic updates on general conditions in the Teton Range throughout the winter.
