ABSTRACT
In 1959–1960 Arizona Archaeological and Historical Society members excavated the ruins of an Anglo-American ranch house in southern Arizona dating between 1859 and 1903. Pottery, stone, and shell Piman-Indian artifacts were recovered, but most artifacts were non-Indian: metal, paper, rubber, pottery, and glass. These are analyzed and described in detail, especially square cut nails and tin cans. The site vegetation is also analyzed and a discussion of tree-ring dating of mesquite and ash trees is included. The site is typical of western frontier ranch house sites; the artifacts have a common distribution throughout the United States.
