About 1/4 mile below Dead Horse Lake, the trail intersects with the East Fork Blacks Fork trail going to Red Knob Pass. By following this trail east for 2.5 miles you come to Red Knob Pass. The trail up to the pass is steep and rocky. As you reach the top, you will see four drainages in the following order: The main fork of the West Fork Blacks Fork from which you just came, a small eastern fork of the West Fork Blacks Fork, the Lake Fork, and the East Fork Blacks Fork. It is possible to descend into any of these, so bring your topographical map and make sure you have the right drainage before starting down. Above Dead Horse Lake, a steep rocky trail leads up the ridge to Dead Horse Pass. This trail is a tough climb, not recommended for inexperienced high-country travelers. From Dead Horse Pass a trail leads south and down into the Rock Creek drainage. Both Pass's (Red Knob & Deadhorse) are often covered with snow late into summer, especially Dead Horse Pass. Ask for current conditions at the Ranger Stations.

From Highway U-150, two miles north of the Bear River Ranger Station, turn east onto the North Slope Road (follow sign directing to the Blacks Fork River). Travel about 16 miles along this road over Elizabeth Pass and down the other side, until you come to its junction with Lyman Lake Campground road. Take a right turn and proceed to the next junction. Take another right turn, a sign directing you to the West Fork Blacks Fork, and drive 4 miles to a major river crossing. Park here, cross the river on a log just up stream, or at the sheep bridge just down stream, and follow the dirt track on foot. At approximately 3.5 miles you will have to cross the stream again. This area is called the Scalers Cabin where the buck and pole fence is located. At this point, you are within 1/2 mile of the High Uintas Wilderness Boundary. Just past the wilderness boundary, approximately 1/4 mile, you will have to cross the stream again. From this point on, the trail (though hard to follow through the meadows) stays on the east side of the river. There are a few river crossings, but the logs are adequate.

This area comprises the head waters of the West Fork Blacks Fork River. The canyon bottom opens up into lush green meadows, conifer forests and views of high rocky peaks. Dead Horse Lake is quite a bit larger, but both have fair fishing late in the season. There are good camping spots in the Dead Horse Lake area.
