Twins in America - Yellowstone River

Twins Ashley and Alyssa at the Yellowstone River

The Yellowstone River originates in Wyoming and flows through Yellowstone National Park before entering Montana and eventually meeting up with the Missouri River just across the North Dakota border. It is the longest (671 miles) undammed river in the continental United States.

The river has also been a major factor in the settlement of southeastern Montana, and retains much cultural and historical significance. It is also one of the premier trout-fishing rivers in North America.
