About this map

Palo Alto Battlefield National Historical Park anchors the southern portion of this 2019 survey, preserving the site of the first major battle of the Mexican-American War. The landscape is defined by the unique hydrology of the Rio Grande Delta, where winding resacas—former distributary channels of the river—now serve as local water bodies and landmarks. Notable examples include Resaca de los Cuates and Resaca Reparo near Bayview, alongside the sprawling Tule Lake Bed and Dana-Tule Reservoir 1.

The city of Los Fresnos serves as a central hub, surrounded by a dense network of residential colonias including Del Mar Heights Colonia, Chula Vista Colonia, and Orason Acres Colonia. The map also highlights the ecological significance of the region, showing the boundaries of the Lower Rio Grande Valley National Wildlife Refuge and Laguna Atascosa National Wildlife Refuge. Transportation and infrastructure are represented by Drennan Farm Airport and a grid of rural roads like FM 1847 that connect small settlements like Laureles and Indian Lake.
