About this map

Oak Island and the rural community of Thelma occupy this landscape south of San Antonio, where the terrain begins to transition across the Bexar and Atascosa county line. The drainage of the Medina River and its associated Medina River Greenway dominate the northern portion of the sheet, while a network of creeks including Gallinas Cr, Galvan Cr, and Elm Cr carve through the southern plains.

Transport patterns reflect a mix of established regional arteries like Palo Alto Rd and S Loop 1604 W alongside local landmarks such as Cannon Field. The area is characterized by residential expansion into previously agricultural or open lands, evidenced by the dense naming of local lanes such as De Vilbiss Ln and Genevia Irene near established settlements. To the east, Pax Lake and Palo Blanco Cr provide further geographic definition to this South Texas corridor.
