Springing from the high mountain peaks close to the Montana/Wyoming border at the western end of the Beartooth All-American Road, the Clark’s Fork of the Yellowstone River parallels the highway for 17 breathtaking miles. The Clark’s Fork River leaves the Beartooth Highway and continues its journey northeast as it parallels the Chief Joseph Scenic Highway traveling toward the famous Clark’s Fork Canyon. Named after William Clark of the Lewis and Clark Expedition, the Clark’s Fork flows through a deep, postcard-scenic canyon. Its tumultuous waterfalls, white water cascades, deep pools, and rugged corridor lands are its unique characteristics. The Clark’s fork was designated Wyoming’s first Wild and Scenic River in November of 1990, and it is one of only two rivers in the state with the Wild and Scenic designation.
