17 miles of the Yellowstone River flow through North Dakota. The shoreline is bordered by tall steep bluffs with several sandbars and is home to a variety of wildlife. The Lewis and Clark expedition crossed this path and two historic sites still remain at the confluence. This segment begins at Sundheim Park and flows to the Confluence of the Missouri River. Some hazards to be aware of are submerged trees, sandbars and possible high winds from the north.
