1951 Map of Theba

Southward, the terrain shifts abruptly from the irrigated flats into the White Hills and the craggy heights of the Sauceda Mountains. Large tracts of land are designated as part of the Williams Military Reservation, while the northern edge of the map includes a portion of the Gila Bend Indian Res. Cultural markers like the Cemetery near the river and the Smurr siding provide important touchstones for genealogical research in this sparsely populated stretch of Maricopa County.
