White Cliff of Lewis & Clark This 149-mile section of the Missouri River is the only major portion that has been preserved in a natural and free-flowing state. It is a remarkable float trip for canoers and rafters and is suitable for beginners. Along the way, habitats change from rolling grasslands to beautiful white cliffs to rugged badlands. Turkeys are common, and the chances of seeing bighorn sheep are very good, particularly after August of each year. Directions: The main access points are on the Marias are at Tiber Dam, the Circle Bridge on state Hwy 223 between Fort Benton and Chester, and U.S. Hwy 87 at Loma. No visitor services are provided on the Marias River. Bureau of Land Management P.O. Box 1160 Lewistown, MT 59457 Phone: (406)-538-7461 Email: This email address is being protected from spambots.
