Monument Management
Upper Missouri River Breaks National Monument was established by presidential proclamation on January 17, 2001, to protect an array of historical, geological, and biological resources. From Fort Benton to the Charles M. Russell National Wildlife Refuge, the monument spans 149 miles of the Upper Missouri River and encompasses 377,000 acres of adjacent Breaks country, including portions of Arrow Creek, Antelope Creek, and the Judith River.
The monument includes six wilderness study areas, the Cow Creek Area of Critical Environmental Concern, segments of the Lewis and Clark National Historic Trail and the Nez Perce National Historic Trail, the Fort Benton National Historic Landmark, a watchable wildlife area, and the Missouri Breaks Back Country Byway. In 1976, Congress designated the Missouri River segment and corridor in this area a National Wild and Scenic River.
In some areas, the BLM lands are intermingled with State of Montana lands and private property. The monument designation applies only to the BLM-managed lands.
