Natural Features
Slough Creek Campground is on the park's Northern Range, a few miles from where Slough Creek meets the Lamar River. The Lamar Valley is a major summer ground for bison and elk, which attracts predators like wolves and grizzly bears, making it an excellent place to view wildlife.
Elk, bison, deer, and pronghorn thrive in the grasslands of this area, known as the northern range. In fact, some of the largest wild herds of bison and elk in North America are found here. The northern range is critical winter habitat for these large animals, which in turn provide food for several packs of wolves. Coyotes are also common, and occasional bobcat, cougar, or red fox are reported. The gorge and cliffs between the junction and Tower Fall provide habitat for bighorn sheep, osprey, peregrine falcons, and red-tailed hawks. Both grizzly and black bears are sighted throughout the area, particularly in the spring. Black bears are more commonly seen around Tower Fall and Tower Junction. Grizzlies are sometimes seen in the Lamar Valley and on the north slopes of Mount Washburn, particularly in the spring when elk are calving. Road pullouts provide excellent places from which to watch wildlife.
The campground offers access to the Slough Creek Trail, which follows a historic wagon trail into the Absaroka-Beartooth Wilderness beyond Yellowstone. It begins with a steep climb then descends to the first meadow. Stop and relax here or continue to the second meadow. Be alert for bears and moose. Slough Creek is a popular fishing area.
