Greater Yellowstone

The longest free-flowing river in the lower 48 states, the 670-mile (1,080-kilometer) long Yellowstone drains the national park into the Missouri River system. Originating in the Absaroka Mountain Range the river flows north through the park, flowing across the plains of Montana and North Dakota, meeting up with the Missouri River near Buford, North Dakota.

In Yellowstone National Park, its deep, colored canyon and high, misted waterfall are hallowed views.
