The Rio Grande snakes through the southern reaches of this borderlands landscape, defining the international boundary between United States of America and Mexico. The northern half of the sheet reveals a dense network of residential colonias and established communities concentrated along the Military Rd and Highway 83 corridor. Established settlements like La Joya, Perezville, and Penitas are surrounded by numerous named residential developments including Colonia Camargo, Colonia Martinez, and Tierra Maria Colonia. Local history is anchored by the San Antonio Cem and San Jose Cem, while the industrial and utility infrastructure is represented by the Edinburg Settling Basin and Moore Airpark. The presence of Walker Lake and Penitas Lake near the river indicates the characteristic oxbow hydrology of the valley, supporting a mix of residential expansion and agricultural proximity.
