San Bernardino Ranch

San Bernardino Ranch is a historic ranch house in the southern San Bernardino Valley, near the San Bernardino National Wildlife Refuge in the extreme south-east of Cochise County, Arizona. The ranchland and valley form part of the headwaters region of the Yaqui River. The ranch is significant for its association with the beginning of cattle ranching in southern Arizona and northern Mexico. It is also known as the Slaughter Ranch, having been the home of the lawman John Horton Slaughter from the 1880s until his death in 1922. In 1911, during the conflict known as the Border War, a United States Army camp was established at the ranch and called Camp San Bernardino Ranch, or the Slaughter Ranch Outpost. The site was declared a National Historic Landmark in 1964 for its association with Slaughter. The compound now includes the preserved ranch house, wash house, icehouse, granary and commissary, much of it set up as the Johnson Historical Museum of the Southwest.
