Here the southern trail of explorers, trappers, soldiers, and emigrants crossed ancient trade routes of Kamia, Cahuilla, Diegueno, and Luiseño Indians. On the flat southwest across the creek, Warren F. Hall built and operated the San Felipe home station of the Butterfield Mail, which operated from 1858 to 1861. Later the station was used by Banning Stages and by the military during the Civil War.
