John Colter was a member of the Lewis and Clark Expedition (1804–1806). Though party to one of the more famous expeditions in history, Colter is best remembered for explorations he made during the winter of 1807–1808, when he became the first known person of European descent to enter the region which later became Yellowstone National Park and to see the Teton Mountain Range. Colter spent months alone in the wilderness and is widely considered to be the first known mountain man.
The Bob Marshall Wilderness Area is a congressionally-designated wilderness area located in Western Montana region of the United States. It is named after Bob Marshall (1901–1939), an early forester in the federal government, conservationist, and co-founder of The Wilderness Society. In the 1930s while working for the Forest Service, Marshall was largely responsible for designation of large areas to be preserved as roadless within lands administered by the Forest Service; he achieved this through promulgation of various regulations. Formally designated in 1964, the Bob Marshall Wilderness extends for 60 miles (97 km) along the Continental Divide and consists of 1,009,356 acres (4,084.72 km2).

Created by an act of Congress in 1983, this rugged alpine wilderness is divided into four separated parcels typified by complex mountain topography: Bear Trap Canyon unit, Spanish Peaks unit, Taylor-Hilgard unit, and Monument Mountains unit. The Bear Trap Canyon unit was the first designated wilderness area to be managed by the Bureau of Land Management, and comprises a region of canyonlands adjacent to the Madison River. The other three sections of the wilderness are jointly managed by Beaverhead-Deerlodge and Gallatin National Forests, both of which are a part of the Department of Agriculture.

The Madison Limestone is a thick sequence of mostly carbonate rocks of Mississippian age in the Rocky Mountain and Great Plains areas of the western United States. The rocks serve as an important aquifer as well as an oil reservoir in places. The Madison and its equivalent strata extend from the Black Hills of western South Dakota to western Montana and eastern Idaho, and from the Canada–United States border to western Colorado and the Grand Canyon of Arizona.

Tower Rock State Park is a state park near the community of Cascade in the U.S. state of Montana in the United States. The centerpiece of the park is Tower Rock, a 424-foot (129 m)-high rock formation which marks the entrance to the Missouri River Canyon in the Adel Mountains Volcanic Field. It was well known to Native Americans, and considered a sacred place by the Piegan Blackfeet. Tower Rock received its current name when Meriwether Lewis of the Lewis and Clark Expedition visited the site in 1805. Railroad and highway development in the late 1800s and 1900s skirted Tower Rock, but the landform itself remained pristine. The 87.2 acres (0.353 km2) encompassing Tower Rock was added to the National Register of Historic Places on March 18, 2002. The 140-acre (0.57 km2) Tower Rock State Park was created around the National Historic Site in 2004.
