This collection includes original card prints, copy prints, cyanotypes, and other photographs chiefly from George Roskruge's survey work in Southern Arizona in the 1890s. Some photographs depict survey markers, surveyors and their camps and equipment but there are also photographs of the people he encountered, depicting ranching and mining activities and forms of transportation. Included are photographs of ranch families as well as Tohono O'odham, Apache and Yaqui groups. The many forms of transportation shown include carts and carriages, wagons, covered wagons, pack mules, and a stage coach. Photographs of the San Francisco River show a horse and wagon crossing the river while images of the Santa Cruz River show flooding, homes along the bank, and a boy crossing the river on horseback. There are photographs from surveys of the San Rafael del Valle land grant, the Babocomari land grant, the Buena Vista land grant, an irrigation ditch, and Sabino Canyon. Mining surveys include the Salero-El Plomo Mine in Santa Cruz County. These photographs show mines, buildings, pack mules carrying ore, and two men bathing in a stream. Unidentified mining photographs include a series of a miner camped by a stream with his gold pan in hand as well as ore cars, a smelter and a water flume. A few photographs show Tucson homes and businesses including Fitzgerald's quarry, Clifton, Ariz. homes and businesses, and the Missions of Tumacacori and Guevavi. There are also portraits of Roskruge and views of his office.
