Thomas Fork Valley serves as the central geographic feature of this borderland, where complex irrigation systems like the Steven Larson Ditch, Halls Ditch, and Etcheverry Ditch support the agricultural life of the basin. The settlement of Geneva sits near the northern edge of the map, while the community of Raymond is situated further south along the Idaho-Wyoming state line. This 2020 survey illustrates how the high-elevation terrain of the Preuss Range and the Sublette Range hem in the valley, dictating the placement of early travel routes and local infrastructure.
