1969 Map of Mirasol Creek

About this map

The Old Nueces River Channel cuts through the northern reaches of this brush country landscape, marking the transition into the ranchlands of McMullen and Duval counties. Surveyed in the late 1960s, the terrain is defined by a network of drainage systems including Ygnacio Creek, San Jose Creek, and the central Mirasol Creek. Human impact on the arid environment is visible through the strategic placement of water features such as Rowland Tank, Pulgas Tank, and Pipeline Tank, essential for supporting livestock at locations like Walker Ranch. Industrial activity is noted in the southern portion of the sheet with scattered Oil Wells, while the presence of a Control Tower and Observation Tower in the northwest suggests a specialized use of this open territory. The boundary between McMullen and Duval counties bisects the quadrangle, providing a precise reference for land ownership and local jurisdiction during this era.
