About this map

Cibolo Ranch serves as the focal point for this 1960s survey of South Texas rangeland, where the scarcity of surface water shaped every aspect of human presence. Life and industry in this portion of Webb County revolve around a network of engineered watering holes and deep groundwater access. Named reservoirs like Kuykendall Tank, Callaghan Tank, and Borregos Tank dot the landscape, providing essential resources for livestock in a territory defined by Chacon Creek and San Ygnacio Creek.

Evidence of early ranching families and international naming traditions appears through labels like Juan De Leon Well, Buenos Aires Well, and De Cavasos Tank. The infrastructure of the era is marked by the San Ygnacio Road and a complex system of fence lines, which the Geological Survey specifically highlights with fine red dashed lines. This map preserves the mid-century layout of a working borderlands landscape before modern consolidation changed the footprint of these traditional holdings.
