Eagles Nest Wilderness begins about 4.3 miles away, and it is the closest of these.

Each unit is published as a centre point and an acreage rather than a boundary, so this section stands it in for a circle of the same area. Whether a campground is inside, and how far it is from one it is outside, are both approximate.

Natural features

In the heart of the Rocky Mountains, the 2.3 million-acre White River National Forest is a place of serenity and adventure, boasting eight wilderness areas, four defined seasons and ten peaks surpassing 14,000 feet in elevation. The White River National Forest was established in 1891 as the White River Plateau Timber Reserve; the second such reserve to be named in the United States. In 1905, the newly formed Forest Service was given authority of the reserve. Long before this designation, the area was home to the Ute Indians who followed herds of elk and bison on their seasonal migrations. Wildlife in the area abounds. Bighorn sheep navigate rocky ridges and bull elk bugle at dusk. Scenic rivers sustain populations of cutthroat, rainbow and brown trout. Alpine regions provide habitat for pika and ptarmigan.

Recreation

Encompassing a landscape of rivers, mountains, trails and forest roads, the White River National Forest is one of the top recreation forests in the nation. Located on the shores of Green Mountain reservoir, Cow Creek Campground is a popular spot for boating, canoeing, fishing, water skiing and windsurfing. Anglers will find populations of rainbow and brown trout, as well as kokanee salmon when casting their lines out into the water. Spring Creek is a popular off-roading area located at the northern end of the Gore Mountain Range. A network of roads open to off-road vehicle use meanders through lodgepole pine and spruce/fir forests. Viewpoints of surrounding mountains open up along these roads.
