As September begins, two large fires near Jackson Hole are contributing to the haze in the valley. The Dollar Lake and Willow Creek fires are burning close to Jackson—both about 80 miles away and mostly uncontained. It’s been a super dry summer, so fire danger remains high across all public lands in Jackson Hole. For more information: Wyoming Fire Report »
September brings cooler temperatures and marks the seasonal transition to fall. It’s a dynamic month: animals are mating, fall migration is underway, town events are happening, and the bugle of bull elk fills the air.
This is also a month of giving, highlighted by Old Bill’s Fun Run—tagged a “marathon of generosity.” The event takes place on September 6, 2025, and began back in 1997 with a generous gift from the anonymous Mr. and Mrs. Old Bill, who established a matching campaign for all donations. It’s a true community event and a wonderful way to support local nonprofits. Over the years, the annual event has raised more than $280 million. The giving season continues through September 12, with plenty of opportunities to volunteer as well. For info or to participate: oldbills.org »
The elk bugle reaches its peak around the autumnal equinox on September 22, 2025. Elk use their voices—and their breath—to produce a haunting call that rises to a high note before dropping into a series of grunts and squeals. They add energy from the trunk of their bodies, giving the sound a roaring or yelping quality. This vocalization attracts females and warns other bulls: “This is my territory.” It’s an otherworldly, magical sound to experience. My favorite places to listen are Lupine Meadows or White Grass Ranch in Grand Teton National Park.
There’s also plenty of fun to be had. The Fall Arts Festival takes place this month, offering numerous art events and experiences. Learn more: Fall Arts Festival »
Enjoy the start of fall.

Call to Action!
President Trump is attempting to remove protections under the “Roadless Rule” on 45 million acres of forest land. This rule limits road-building and helps keep our forests wild. Now, the Department of Agriculture is pushing to repeal it, opening the door to logging and development.
The public has been given only three weeks to comment—so now is the time to act. Let’s speak out for wild nature and ensure this land remains protected. If these changes go through, all species will be affected—and the sense of “wildness” could be lost forever.

Backcountry Tips
- Always let someone know where you’re going. Even if it’s a relative who doesn’t live locally, it’s critical someone knows your plans. Consider downloading the Backcountry SOS app—it connects you directly to local search and rescue with just a couple of taps. Simple and potentially life-saving.
- With fall approaching, be ready for colder temperatures. You can feel the whisper of autumn in the air, and it gets especially chilly at higher elevations. Wind only makes it colder. Now’s the time for extra layers and no cotton—stick to warm, moisture-wicking materials.
Field Facts
- Elk are bugling in the northern parts of Grand Teton as September begins. Take time to enjoy this haunting and powerful sound—it’s one of the true highlights of the season.
- Bears are on the move as they search for food. Their home ranges vary depending on food availability. A bear can travel 20–40 miles in a single day, and grizzly bears may roam across hundreds of square miles. This year’s dry vegetation affects all species and may influence wildlife movement patterns.
Tour Suggestions
It’s that time of year—fall colors are on the way! Aspen trees will start turning golden a bit earlier than the cottonwoods, while other plants burst into brilliant shades of red. It’s a great time to get outside, play, and soak in the color. Munger Mountain offers beautiful aspen groves, and Phelps Lake is especially peaceful this time of year, with a slower, quieter pace. By the end of the month, anything along the river will be glowing with color. Even the bike paths through Grand Teton Park become part of the mosaic—perfect for a scenic ride. Enjoy the season, and don’t forget to dress for changing fall weather.
