CHANGING SEASONS - SEPTEMBER 4, 2020

 

Jenny Lake rangers in technical rescue training last week, Disappointment Peak

As we transition into September, conditions on the high peaks have remained primarily dry and favorable. Labor Day weekend is shaping up to be busy in the backcountry, with lots of climbers and hikers taking advantage of the good weather. However, with rain and snow in the forecast for the beginning of next week, conditions are likely to begin changing in the mountains as we move toward the fall season.

Climbers attempting popular routes on the Grand such as the Owen-Spalding and Exum Ridge should be prepared for shifting weather, unexpected alpine conditions, and cold nights which can produce ice and verglas on shady aspects. Weather and climbing conditions in the Tetons can change rapidly with each passing storm. Adequate preparation, appropriate gear, and self sufficiency are of the upmost importance when venturing into the mountains, especially during this time of year.

The Jenny Lake ranger station will close for the season at end of day, September 7th. The staff will make an effort to update conditions for the Grand and other popular peaks throughout the remainder of the month, however, expect alpine conditions in the mountains as we move toward the end of summer.

IT'S PEAK SEASON - AUGUST 13, 2020

 Paintbrush Divide - 7.30.20

As of mid-August, the backcountry of Grand Teton is bustling, and popular camping zones throughout the Teton Crest Trail and Garnet Canyon are filling up every day. Hikers and climbers hoping to receive walk-in permits for backcountry itineraries should plan to be at the permit office or Jenny Lake ranger station as early as possible the day before they want to begin their trip to ensure they have the most options for their trip.

Lingering snow in typical problem areas is finally beginning to recede. The entirety of the Teton Crest Trail is now essentially snow free. Paintbrush Divide, which required an ice axe for safe passage as little as a week ago, is now navigable without an ice axe. With that being said, lower angle snow patches still exist and trekking poles may be helpful when crossing these areas. Avoid the upper early season boot pack that still exists as it presents an unnecessary steep snow crossing that has been the site of two serious accidents this season. The approach to the Lower Saddle and routes like the Owen-Spalding and Exum Ridge are now free of snow and passable without ice axe or crampons. Be mindful of changing weather in the coming weeks. Afternoon thunder storms should be expected, and any combination of recent precipitation and cold temperatures up high can provide wet and icy conditions despite any given climb being described as "dry" or "snow free."

The closure of Baxter's Pinnacle for nesting peregrine falcons has been lifted.  It is open for climbing traffic.
