Before the Butterfeild Line, in 1857, Antelope Peak was nearby the location of one of the water and camp sites of the San Antonio-San Diego Mail Line between its stations at Maricopa Wells and Jaeger City, California, location of Fort Yuma Station, which was also the site of the ferry across the Colorado River just down river from Fort Yuma. Antelope Peak Station was 20 miles west of Peterman's Station and 24 miles east of Little Corral, 40 miles east of Jaeger City. Given the proximity to grass near the mountain referred to below and the Gila River nearby it made a good overnight camp.
