The Rio Grande meanders along the southern border of this region, defining the international boundary between the United States and Mexico. North of the river, the landscape transition from the wetlands and oxbows of West Lake and Carlson Lake into the residential and agricultural grid of South Texas. The settlement of Las Milpas sits between the larger municipalities of Hidalgo, Pharr, and San Juan, reflecting the dense development patterns along the border. For those researching local family history, the map is remarkably dense with burial sites, ranging from the Santa Ana Cem near the riverbanks to the centrally located Jackson Ranch Church Cem and Eli Jackson Cem. The intricate network of local roads, such as Old Mil Rd and W Highline Rd, connects these community landmarks within the Lower Rio Grande Valley.
