Two hundred years ago, Meriwether Lewis and William Clark stood high on a ridge-line that divides continental waters, and began the discovery of the Pacific Northwest. Stands of fir and oine trees, high-mountain meadows and rolling, jade-colored hills look much the same today as when the famous explorers journeyed to the crest of Lemhi Pass in 1805.
As you travel the Lewis and Clark Back Country Byway, you'll see where the expedition unfurled the flag of the United States for the first time west of the Rocky Mountains, as well as spectacular vistas of the Lemhi Pass, Salmon River, Rocky and Lost River mountain ranges, rolling sagebrush and alpine meadows, wildlife, and carpets of wildflowers.
