2020 Map of Twin Bridges SW

About this map

The Big Hole River winds through the southeastern corner of this Madison County landscape, defining a low-lying riparian corridor marked by Third Slough, Owsley Slough, and the aptly named Schoolhouse Slough. This modern survey reveals a rugged transition from these river bottomlands into the arid, dissected hills of the Highland Mountains. Transportation is centered on the Melrose-Twin Bridges Co Rd, which cuts across the drainage basins of Rochester Cr and Nez Perce Cr. While the terrain remains largely open range, localized developments such as Garnet, Sundust, and Walking Horse appear near the central Valley View Drive corridor, indicating modern residential or ranching divisions within the historic township and range system. The geography is characterized by seasonal water sources like Cottonwood Cr and the 03S07W05DCBB01 Spring in the northern reaches.
