Upper Missouri River Breaks National Monument

The Upper Missouri River Breaks National Monument (UMRBNM) covers about 375,000 acres of BLM-administered public land in central Montana. These lands hold a spectacular array of plant life, wildlife, unique geological features, endless recreational opportunities and significant historical and cultural values. The rugged landscape has retained much of its unspoiled character over the centuries and, as a result, offers outstanding opportunities for solitude and dispersed recreation. 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. Landowner permission is required prior to using private property for any activity. A permit is required for recreational use of state lands.
