2011 Map of Seneca

About this map

Corrumpa Creek and its various tributaries define this corner of Union County, carving a network of drainage features through the high plains landscape. The topography is marked by distinct landmarks such as Lookout Hill and The Pyramid, which provide significant relief above the surrounding terrain. In the northeast, the land drops into Barrel Canyon and follows the winding path of Corrumpa Creek past a marked Waterfall. The road network is largely rectilinear, following section lines typical of the rural West, with named routes like Corrumpa Rd and Campbell Rd connecting isolated ranching or agricultural operations. In the southeastern corner, the small settlement of Seneca serves as a local hub, anchored by the Seneca Post Office near the junction of Co Rd A087 and Angus.
