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.

September 20th, Snow in the high country

A recent storm system has deposited snow above the 9,000 foot level. Clear skies and warmer temperatures over the weekend have melted much of the snow, but expect snow and ice to linger for quite some time above 10,000 feet, especially in shaded areas.



The Jenny Lake Ranger Station is closed for the season. Backcountry camping permits can be obtained at the Craig Thomas Discovery and Visitor Center in Moose or the Colter Bay Visitor Center in Colter Bay. Call 307-739-3309 for more information.

As we move into fall, climbers and hikers should be prepared to deal with changing conditions, including:

·         Snow, ice and verglas in shaded areas, especially on north and west aspects above 11,000 feet

·         Freezing overnight temperatures. On average, temperatures drop 3 degrees for every 1,000 feet of elevation gain.

·         Shorter days- usable light until 7:30-8:00 pm.

·         Rescue operations can be limited by reduced staffing, severe weather and limited helicopter use. Consider your climbing objectives carefully and be prepared for self-rescue.    

Specific route condition updates will be limited as we transition to fall and staffing is reduced. This HOMPAGE will continue to provide significant updates on general conditions throughout the winter.
