Thomas Fork winds through this high-altitude valley on the Idaho-Wyoming border, anchoring a landscape defined by ranching and water management. Small settlements like Geneva and Raymond serve as local hubs, connected by a network of rural routes such as Center Ln and Wood Canyon Rd. The irrigation infrastructure is remarkably dense here, with the Geneva Ditch, Taylor Canal, and Halls Ditch diverting water across the valley floor to support operations like the G H Hall Ranch and Mumford Ranch.
