2020 Map of Border

About this map

Border Junction sits at a critical geographic and political intersection where the Bear River and Thomas Fork meet amidst the high-altitude terrain of the Sublette Range and the Preuss Range. This 2020 map documents the intricate water management systems essential to the Thomas Fork Valley, featuring an extensive network of irrigation infrastructure including the Raymond Canal, Etcheverry Ditch, Miller Ditch, and Cook Canal. These systems demonstrate how the landscape has been engineered to support life and agriculture along the Idaho and Wyoming state line. Small settlements and named locations like Border and Chausse provide evidence of localized hubs within the broader valley. The topography is defined by significant landmarks such as Border Summit and the Sheep Creek Hills, while lower-lying areas like Horse Valley and Swine Bend Hollow illustrate the varied relief of this borderland region.
