Caribou-Targhee National Forest

Targhee National Forest lies along the Continental Divide, at the uppermost reaches of the Columbia River Basin, an ecosystem of 40 million acres extending from Western Washington to the Southeastern Idaho border and encompassing parts of Montana, Wyoming, Nevada, and Utah.

The Forest includes all or portions of several distinct mountain ranges, including the Lemhi, Beaverhead, Bitterroot, Centennial, Henry's Lake, Teton, Big Hole, Caribou, and Snake River Ranges. Elevations range from near 5,000 feet on the Snake River to over 12,000 feet on the Forest's western and easternmost reaches.

Targhee contains the Island Park Caldera and several reservoirs. The Jedediah and Winegarhole Wildernesses lie within the Forest. The Forest is on the border of Montana and Wyoming, near Yellowstone National Park. The closest city is Idaho Falls.
