Warmer and drier weather over the past two weeks has reduced the amount of, but not eliminated, the snow and ice lingering on shaded ledges high in the Teton Range.  An ascent of the Upper Exum remains manageable without an ice axe or crampons, however, we continue to recommend carrying crampons, and perhaps an ice axe, for descent of the Owen-Spalding.  An ascent of the Owen Spalding requires an ice axe and crampons.  Recent reports from climbers indicate that the East Face of Teewinot and the SW Couloir of the Middle Teton can be ascended without crampons. The Lower Saddle Patrol Hut and weather station have been taken down for the season. Seasonal fall weather can dramatically change these conditions at any time so pay attention to what the weather is doing day-to-day if planning an ascent in the high peaks.

Fall weather brings changing colors down low and snow & ice up high!

Climbers and hikers are reminded that fall brings changing conditions that they should be prepared to deal with, including:
  • Snow, ice and verglas in shaded areas, especially on north and west aspects above 10,000'
  • Freezing overnight temperatures
  • Shorter days - usable light only lasts until about 7:30 - 8:00 pm
Backcountry camping permits are required year-round for all overnight trips into the backcountry of Grand Teton National Park.  Climbers and hikers can obtain backcountry camping permits at the Craig Thomas Discovery & Visitor Center in Moose.
