The Teton River originates in the Bob Marshall Wilderness and flows through a variety of mountainous and flat terrains. The river has sometimes been called the Rose River for the plentiful wild roses which are seen along its banks. Indians called the river the Titan, which referred to the “land without trees” through which it flows. The Teton River is a tributary of the Marias River, approximately 150 mi (241 km) long, in northwestern Montana in the United States. It rises in the Lewis and Clark National Forest, in the southern Lewis Range of the Rocky Mountains at the continental divide. It flows southeast, then east, down from the mountains and across Teton County, past Choteau, and is joined by Muddy Creek and Deep Creek. It flows east, passing near Fort Benton and joins the Marias only 3 mi (5 km) upstream of the confluence of the Marias and the Missouri. Click here for more information.
