Photographs taken and collected by Paul Reiter during his time with the UNM field schools and the Museum of New Mexico. Includes images of UNM field school excavations in Chaco Canyon between 1929 and 1941. Most of the images show excavations at Chetro Ketl, but also include Talus Unit 1, BC 50, 51, 52, and 53, Threatening Rock, and Pueblo Bonito. The majority of these images are copies of photographs held at the Museum of New Mexico which were acquired by the Chaco Project in the 1980s. The Chaco Project placed the photographs on photocards and, in some instances, made copy prints and negatives. Many of these photographs are attributed to Paul Reiter or John Russell; however, some of the photographs may have been taken by other UNM field school students. Also includes a set of aerial photographs of Chaco Canyon which belonged to Paul Reiter while he was a professor in the UNM Department of Anthropology. These aerial photographs were most likely taken between 1927 and 1935, possibly by Carlos Vierra
