Montezuma Castle National Monument, Arizona (1977)

The handbook explains how volcanic and limestone processes shaped the Verde Valley, producing a limestone sink with a spring-fed well and a cliff cavity later used for a multi-story cliff dwelling. It summarizes archaeological evidence indicating Sinagua farmers occupied the area from the 1100s to the 1400s, describing pottery, tools, and domestic remains that illuminate pueblo life. It outlines the architecture and condition of the cliff dwelling and the nearby sinkhole lake, and traces the site's designation and administrative history. The guide interprets the surrounding natural environment, offers practical visitor information, provides a glossary of terms, and lists suggested readings.
