Recent storms have deposited more snow throughout the range. Expect to encounter significant amounts of unconsolidated snow above 9,000 feet, below that elevation the snow coverage is roughly 4-6 inches. For the most up to date snow conditions please refer to the Bridger Teton National Forest Avalanche Report at: http://jhavalanche.org/viewTeton , pay particular attention to the Snowpack Summary.
As of November 22nd none of the valley lakes are frozen over.   

October 11, 2016

We have received quite a bit of snow and rain over the last 10 days. This past weekend we experienced warmer temperatures in the valley, but most of the snow above 10,000 feet stayed, so expect ice and snow to linger in shaded areas and north facing peaks. Cold mornings and shorter days have not allowed for melting in these areas and any new storms will most likely compound existing winter conditions. Most of the classic couloirs, like the Black Ice Couloir, have not received enough melt-freeze to make for adequate alpine ice. This is not a good time of year to attempt long climbs for the first time and climbers should be prepared for rapidly changing weather patterns.  


Getting lots of reports of "full conditions" above 11,000 feet with ample snow and ice on north and west aspects.  Expect conditions to remain this way until winter. 

Frosty conditions on Owen, The Grand, & The Middle - 9/28/16
West side of Mt Owen & The Grand Teton - 9/28/16


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 Homepage will continue to provide periodic updates on general Teton Range conditions throughout the winter.
