The Rio Grande serves as the international boundary between the United States of America and Estados Unidos Mexicanos in this 2010 survey of South Texas. The river’s meanders define the landscape, leaving behind historically complex land divisions such as Casa Banco Number 90 and Los Adjuntas Banco Number 91. The area south of Rio Grande City is characterized by a dense network of colonias and established settlements, indicating significant local growth and residential development near the border.
