About this map

Laguna Madre defines the eastern edge of this coastal survey, where the intricate hydrology of the Rio Grande delta meets the Texas coast. The landscape is dominated by winding resacas—ancient distributary channels of the Rio Grande—including Resaca de los Cuetes and Resaca de la Leona. These serpentine water bodies create a complex terrain of ridges and depressions that dictated early settlement and transportation patterns in Cameron County.

Settlement is sparse but strategically placed near these water sources and transportation lines. La Coma Ranch sits near the head of a major resaca, while the San Benito and Rio Grande Valley railroad cuts through the southern portion of the map, serving the community of Abney. Along the shore, Holly Beach and the high ground of Morando Blanco mark the transition to the shallow waters of the lagoon and its extensive Mud Flats.
