A RIVER OF HISTORY: CONNECTING OUR PAST, PRESENT, AND FUTURE (204 Main Street) And through our past, present, and future run the Main Salmon (“The River of No Return”), the Middle Fork, the Lemhi, and Pahsimeroi Rivers. These waterways, along with the mountains, define this place and direct its development, settlement, and adaptations to change. The “River of History” museum–as part of the Lemhi County Museum–features river-related artifacts, photographs, and biographies. Interpretive panels discuss streambed restoration, anadromous fish, culture, and community. It includes exhibits on backcountry flying and geology. This building is also home to THE SHIRLEY WALKER LEMHI COUNTY HISTORY RESEARCH CENTER, VISITOR CENTER, AND CHAMBER OF COMMERCE.
