About this map

Thomas Fork Valley anchors this 2010 survey of the Idaho-Wyoming state line, where the winding Bear River meets its tributaries amidst a complex system of irrigation and ranching infrastructure. Small settlements such as Border Junction, Border, and Chausse sit along the primary transit corridors of Pegram Rd and the crossing into the Sheep Creek Hills. The landscape is defined by the high-elevation transition at Border Summit and the branching waters of the Thomas Fork, which is diverted into the Raymond Canal and Etcheverry Ditch.

Downstream, the hydrography becomes increasingly dense with the Cook Canal, North Willow Creek, and South Willow Creek feeding into the river valley. The map details a rugged geography of canyons, including Layland Canyon and Groo Canyon, alongside family-named access routes like Munford Rd and Johns Ln, providing a precise record of the land-use patterns and water rights vital to this high-desert borderland.
