The Upper Missouri River Breaks National Monument contains a spectacular array of biological, geological, and historical objects of interest. From Fort Benton to the Charles M. Russell National Wildlife Refuge, the monument spans 149 miles of the Upper Missouri River, the adjacent Breaks country, and 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. The area has remained largely unchanged in over 200 years since Meriwether Lewis and William Clark traveled through it on their epic journey. Within the monument you can float the river, fish, hike, hunt, drive for pleasure, find a little solitude, enjoy a sense of exploration in a remote setting or simply marvel at the variety of natural beauty.
