About this map

Thomas Fork Valley serves as a critical geographic corridor where the high desert terrain of the Preuss Range meets the agricultural and ecological complexities of the Idaho-Wyoming state line. This modern 2023 survey documents a landscape defined by water management, where the Raymond Canal, Cook Canal, and numerous irrigation works like Miller Ditch and Sights Ditch support the valley floor. The map highlights the Bear Lake National Wildlife Refuge, indicating the intersection of federal conservation interests and local ranching operations.

Transportation and small-scale settlement center around Border Junction and the small community of Border, positioned where Old Hwy 30 and Pegram Rd navigate the gaps between the Sublette Range and Boundary Ridge. The presence of labels such as Chausse and various family-named roads like Munford Rd and Walter Ln provides specific points of interest for genealogists tracing local land use and family heritage in this remote corner of Bear Lake County.
