From 1861 to 1865 in the American Civil War the abandoned stage station was a military outpost of the Union Army called Camp San Filipe, a rest stop on the road between California and Fort Yuma and the Arizona and New Mexico Territories [REF].
After the war, later stage lines from California to Arizona used the station from 1867 to 1877, before the railroad reached Fort Yuma making the stage route obsolete.
