1956 Map of Willamar

About this map

The Willamar Oil Field dominates this South Texas landscape, defined by an intricate network of pipelines and service roads established in the mid-20th century. While the industrial footprint of the field is substantial, the map also preserves the agricultural and ranching heritage of Willacy County. Significant family holdings like El Sauz Ranch and La Jarita Ranch appear alongside worker housing at Willamar Camp, reflecting the dual economy of petroleum and cattle. Water management is a critical feature of this coastal plain, evidenced by the North Floodway, the East Main Drain, and numerous livestock tanks such as Quemada Tank and Sacatosa Tank. Researchers will find localized details including the La Jarita Cem and the small settlement at Porfirio, providing a granular view of the region during a period of infrastructure expansion and land-use revision.
