Boulder River

The Boulder River is a 60-mile long tributary of the Yellowstone River near Big Timber, Montana. It flows north through the Absaroka--Beartooth Wilderness, originating from the northern boundary of Yellowstone National Park. The Boulder River is known for its scenery, whitewater sections, and excellent fly fishing opportunities.
