2022 Map of Keystone Ranch

USGS Topo · Published 2022

About this map

San Miguel Cr and its various tributaries, including Black Cr and Cat Cr, define the drainage patterns of this Frio County landscape. The area is characterized by an extensive network of ranch and county roads, such as Co RD 3300 and Keystone Rd, which link remote ranching properties and homesteads. The terrain rises to the Marshall Hills in the southeast, while Howard Lake provides a significant water feature in the northern portion of the quadrangle. This 2022 survey illustrates the modern layout of rural infrastructure, tracing numerous family-named routes like Heiser Ln that intersect the brushy plains of South Texas. The map also captures the paths of Hackberry Cr and Live Oak Cr, showing how water management remains central to the region's agricultural layout.
