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.
