The
Upper Missouri Breaks National Monument and
National Wild and Scenic River contain a spectacular array of biological, geological, and historical objects of interest. From Fort Benton upstream into the Charles M. Russell National Wildlife Refuge, the
Upper Missouri River Breaks National Monument spans 149 miles river that has been preserved in a natural free-flowing state remaining largely unchanged in the nearly 200 years since Meriwether Lewis and William Clark traveled through it on their epic journey. The Breaks country, and portions of Arrow Creek, Antelope Creek and the Judith River produce a range of wildlife from elk to coyotes to big horn sheep. In 1976, Congress designated the Missouri River segment and corridor in this area a National Wild and Scenic River (Public Law 94-486, 90 Stat. 2327). The monument also encompasses segments of the Lewis and Clark National Historic Trail, the Nez Perce National Historic Trail and the Cow Creek Island Area of Critical Environmental Concern.*
