Russell Creek Trail

Russell Creek Trail #3 runs from Clarks Fork Trailhead to the Fossil Lake junction, about 10 miles each way. The whole out-and-back is roughly 20 miles; budget 10 to 12 hours with breaks. It’s a hard day at altitude, but the route changes from creekside woods to lakes and open alpine country. If 20 miles is too much, Russell Lake is a 12-mile round-trip turnaround about six miles in.

The lower trail starts broad and well traveled. At a signed junction, follow Russell Creek Trail rather than continuing straight; markers are sparse farther along, so pay attention at forks and stick with the clearest tread. The path follows the creek through forest, then opens around Kersey Lake before returning to trees.

Beyond Kersey, the trail climbs through a rocky canyon, with openings above the river. A bridge and a ford are mapped on this stretch; water levels can change with the snow year, so don’t assume a crossing will look like a photo. The higher route reaches Ouzel Lake, where a granite wall rises above the water. It’s a good place to pause and take in the contrast between dark trees, pale rock and the lake.

The woods give way to a broad, exposed plateau of lakes, peaks and drainages. Fossil Lake sits near the high point, around 9,750 feet. Look for the large cairn near the lake where Russell Creek Trail #3 meets East Rosebud Trail #15. For this hike, that junction is the turn; continuing east puts you onto the longer Beaten Path crossing.

Start at the signed Clarks Fork Trailhead off US 212, about four miles east of Cooke City. This is Absaroka-Beartooth Wilderness: there’s no quick exit once you’ve committed to the climb, and the open upper stretch has little shelter. Creek crossings may run high during snowmelt. The Forest Service identifies this as bear country and advises carrying bear spray. Dogs are allowed but must stay under control; the distance and crossings make this a poor fit for many dogs. If camping near Fossil Lake, follow the Forest Service no-campfire restriction there.
