About this map

Twin Bridges serves as the focal point of this 2017 survey, situated at the unique confluence where the Big Hole River and Beaverhead River join to form the Jefferson River. This hydrologic knot is further complicated by the arrival of the Ruby River from the south, creating a rich network of braided channels and sloughs. The landscape is heavily defined by an intricate system of water management, evidenced by features like the Seyler-Tash Ditch, Tash Drain Ditch, and Eastman Ditch that crisscross the valley floor.

Beyond the riverbanks, the map documents several community landmarks including the Twin Bridges Airport and two local burial grounds, the Masonic Cem and Twin Bridges Cem. Transportation routes such as the Melrose-Twin Bridges Co Rd and King Mine Rd provide access to the surrounding gulches and canyons, including Hells Canyon Cr and Goodrich Gulch, illustrating the transition from the fertile river valley to the higher mountain benches.
