FALL UPDATE - SEPTEMBER 21, 2018

Although conditions remain warm and dry, 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.
