1952 Map of South of Potrero Lopeno SE

About this map

Laguna Madre dominates this mid-century topographic study, capturing the intersection of the Texas mainland waters and the barrier island system. This 1952 survey, updated with 1975 aerial observations, illustrates the engineering of the Port Mansfield Channel, a vital maritime artery cut through the shifting landscape. The transition of this coast is evident in the detailed mapping of Padre Island and its designation within the Padre Island National Seashore. The map highlights the dynamic nature of the South Texas coast, where Shifting Sand Dunes and extensive Sand and Mud Flats define the boundary between the quiet lagoon and the open Gulf of Mexico. The county line between Kenedy Co and Willacy Co bisects the northern reaches of the sheet, providing a precise record of administrative boundaries within this coastal wilderness.
