The San Simon Valley is a broad valley east of the Chiricahua Mountains, in the northeast corner of Cochise County, Arizona and southeastern Graham County, with a small portion near Antelope Pass in Hidalgo County of southwestern New Mexico. The valley trends generally north–south but in its northern portion trends northwest–southeast. The San Simon Valley separates the Chiricahua Mountains, Dos Cabezas Mountains and Pinaleno Mountains on the west from the Peloncillo Mountains and the smaller Whitlock Mountains to the east.[1]
