Union serves as the primary settlement on this map, situated where the floor of the Grande Ronde Valley meets the rising terrain of the Eagle Cap foothills. This area is defined by a sophisticated water management system designed for high-altitude valley agriculture, including the Catherine Creek Highline Canal, Prescott Ditch, and Elmer Ditch. These waterways divert flows from Catherine Creek to sustain the local ranching and farming operations. Outside of the residential grid of Union, the landscape transitions into more varied topography featuring Pyles Canyon and Dry Gulch. Local landmarks such as Union Cem and several upland springs, including Wigglesworth Spring and Pursel Spring, provide specific points of interest for those studying the genealogy and rural development of this corner of Union County. The network of roads, like High Valley Rd and Ramo Flat Rd, illustrates the continued importance of access to high-elevation grazing and timber lands.
