The North Fork tour follows the highway between the east gate of Yellowstone National Park and Cody, paralleling the North Fork of the Shoshone River and meandering through some of the most magnificent mountain scenery in the nation. Beginning at the east edge of Yellowstone, U.S. 14/16/20 follows the shallow waters of Middle Creek to Pahaska Teepee.
After the lodge, you pick up the North Fork of the Shoshone River. As you descend through the forest, cliffs and narrow columns of volcanic rock carved by water and ice begin to rise through the trees. These formations, including Chimney Rock, are the remains of ancient volcanic dikes. Soon, the forest thins to a peppering of juniper scattered along the canyon cliffs.
