1940 Map of Chacon Creek

About this map

The borderlands of Maverick and Zavala Counties reveal a landscape defined by expansive ranching operations and water management in the years preceding World War II. Numerous named homesteads such as Musgrave Ranch, Finley Ranch, and Blacks Ranch anchor the territory, reflecting a settlement pattern of large family-held tracts. The drainage network of Chacon Creek and Picoso Creek is vital to this arid region, where man-made infrastructure like Chaparrosa Tank and Mata Oso Tank provided essential water for livestock. Modern energy development is also evident during this period, with a CO Gas Pipeline and the Texas Gas Utilities Co corridor cutting across the terrain near G A Park. This military-origin survey preserves the locations of early ranching families including Fessman, J Hope, and W Clark before the expansion of local energy infrastructure.
