While in Texas, let us pause at Salt Flat, 70 miles east of El Paso, once the site of salt beds that dried up when ranchers drilled for water and the salt lakes vanished. The post office was established in Salt Flat in 1941, moving from nearby Ables. Ben H. Gilmore was the first postmaster of Salt Flat. His post office closed in 1945, but a new one opened in 1947. Today Salt Flat has a handful of dwellings, the post office (zip code 79847), a cafe and a gas station serving travelers visiting Guadalupe Mountains National Park or motoring along the road that runs from El Paso to Carlsbad, New Mexico.
