Twin Bridges serves as the focal point of this hydrologic crossroads where the Beaverhead River, Big Hole River, and Ruby River converge to form the Jefferson River. The landscape is defined by an intricate network of irrigation and drainage infrastructure, including the Seyler-Tash Ditch, Thompson Ditch, and Lewis-Jenkins Ditch, which support the agricultural valley. Local history and genealogy are anchored by the Masonic Cem and Twin Bridges Cem, situated just east and south of the town center near the Twin Bridges Airport.
