This national monument includes an ecosystem that parallels the Upper Missouri National Wild and Scenic River through north-central Montana. Much of the land in this area (377,346 acres) is public land managed by the BLM. In some areas, these BLM acres are intermingled with State of Montana lands and private property. The landscape throughout this monument contains a spectacular array of biological, scientific, historic, wildlife, geological, and cultural resources mixed with a remote location that offers opportunities for solitude not commonly found today.
The "Breaks" begins at historic Fort Benton on U.S. Highway 87 and ends 149 miles later where the Robinson Bridge on U.S. Highway 191 crosses the Missouri River.
