Lytle and Natalia anchor this South Texas landscape where the coastal plains meet the water management systems of the Medina and Atascosa basins. The presence of the Natalia Canal illustrates the area's transition to irrigated agriculture, while the settlement of Coal Mine serves as a reminder of earlier industrial extraction near the Medina Co Atascosa Co line. The terrain is defined by the branching network of the Atascosa River, including the W Prong Atascosa River and N Prong Atascosa River, alongside smaller drainages like Fort Ewell Cr and Chacon Cr. Modern infrastructure is represented by the I-35 Access Rd, which parallels historic routes such as Old Pearsall Rd and Railroad St, tracing the corridor of movement between San Antonio and the Rio Grande Valley.
