The Rio Grande forms a winding international boundary south of Mission and Palmview in this 2016 survey of Hidalgo County. The landscape is characterized by a dense network of colonias, including Tolle Colonia, Leona Colonia, and Conway Plaza Colonia, reflecting the unique residential development patterns of the lower Rio Grande Valley. These settlements are interspersed with significant burial grounds and memorial sites, such as the Rio Grande Valley State Veterans Cem and Valley Memorial Gardens.
