The Rio Grande defines the southern reach of this borderlands region, where shifting river courses have left behind distinctive landforms like Caballeno Banco Number 97 and King Banco Number 48. The landscape is a mix of agricultural infrastructure and residential growth, centered on the settlements of La Joya, Penitas, and Abram. Water management is central to the area's development, evidenced by the Edinburg Pump and the Edinburg Settling Basin near the winding river banks.
