The name Palomino, so one story goes, probably comes from Juan Palomino, a cabellero who in the latter part of the eighteenth century rode a golden colored stallion in the de Anza party out from Mexico across the Colorado desert, over the Sierra Nevada ranges into the great valley of San Francisco to colonize this region for Spain.
