About this map

Ojo de Angua and Noche Bueno anchor a landscape defined by ranching infrastructure and intermittent water sources in this coastal section of South Texas. The interior is characterized by a sparse distribution of family-named wells, such as Estrella Well, Palomas Well, and Tanques de Luis Well, which suggest the critical importance of groundwater for livestock in this arid environment. The map shows the transition from these inland points toward the brackish wetlands and inlets of the Gulf coast.

The western and southern margins are dominated by the aquatic reaches of Alazan Bay and the northern tip of the Laguna Madre. Localized geography like Alazan Mott and Ojo de Agua Spring provide contrast to the large, shallow basins of Laguna Larga and Parra Lake, while the road identified as Ojo de Angua El Martillo provides one of the few primary transit corridors through the salt flats and brush country.
