2013 Map of Thelma

About this map

Oak Island and Thelma anchor this portion of South Texas, where the landscape is defined by the branching tributaries of the Medina River. The area exhibits a mix of rural crossroads and growing residential developments, connected by a network of local routes like FM-1518 and S Loop 1604 W. The drainage patterns of Gallinas Cr, Palo Alto Cr, and Palo Blanco Cr carve through the terrain, leading toward the Pax Lake area. Aviation history is represented by the Cannon Field Airport, while smaller named communities such as Deborah Kay sit alongside established ranch roads. The map reveals the transition of former agricultural land into structured neighborhoods, evidenced by the dense naming of residential streets like those found in Savannah Hts.
