This is a mimeographed copy of the official report resulting from the Rainbow Bridge-Monument Valley Expedition of 1934. These expeditions, which were privately funded and headed by Ansel Franklin Hall, took place from 1933-1938. The work was supervised by Lyndon Hargrave of the Museum of Northern Arizona and the crew consisted of archaeologists, paleontologists, botanists, biologists, and geologists. The report details the group's findings from their archaeological surveys and excavations of several early Anasazi (Pueblo) sites in northern Arizona and southern Utah. It also gives a detailed description of the geology of the region including Monument Valley, Navajo National Monument, the Grand Canyon, Bryce Canyon and Zion National Park, and concludes with a chapter on the modern Indians of the region, the Hopi and Navajo. Also included are maps and seventy-two mounted original photographs. The forward is by Ansel Franklin Hall.
