Located at an elevation of 7,323 feet, Lemhi Pass is a rounded saddle within the Bitterroot Range’s Beaverhead Mountains, situated along the Continental Divide between Idaho and Montana. This pass is where the Lewis and Clark Expedition saw the Columbia River’s headwaters for the first time in 1805. In 1960, the Lemhi Pass was made a National Historic Landmark due its significance to the expedition. The landscape of the pass remains today much as it did more than two hundred years ago. It’s still a remote mountain pass boasting a scenic natural landscape. Use of a high-clearance vehicle is strongly advised.
