2017 Map of Seneca

About this map

Kiowa National Grassland dominates this corner of Union County, reflecting a landscape defined by expansive high-plains grazing and a complex network of seasonal drainage. The settlement of Seneca anchors the southeastern corner, connected to the surrounding range by a grid of rural routes such as Corrumpa Rd and Co Rd A055. The topography is etched by significant watercourses including Corrumpa Cr, which winds through the northern and central sections, and Alamos Cr to the south. Distinctive landmarks like Lookout Hill and The Pyramid rise above the flats, while deep incisions like Road Canyon and Barrel Canyon characterize the northern reaches. This 2017 survey illustrates the modern management of these historical grasslands, showing the enduring ranching infrastructure and the natural draws like Pinco Draw and Gyp Arroyo that dictate the movement of livestock and wildlife across the terrain.
