The San Francisco Peaks rise to a height of over 12,000 feet on the Colorado Plateau of Northern Arizona. The remnants of an extinct volcano, the Peaks are sacred to thirteen Southwestern Indigenous nations; they are home to the Kachina spirits of the Hopi, and they mark the eastern boundary of Dinétah, the Navajo homeland. For residents of the city of Flagstaff, which lies just south of the Peaks, the mountains are a source of water, a symbol of the community, and a crucial part of the regional economy. In the summer, tourists from the hot deserts of central and southern Arizona are drawn to the Peaks for a respite from temperatures that routinely reach the triple digits. In the winter, the Arizona Snow Bowl ski area, located on the western slope of the Peaks, provides winter recreation that is crucial to the winter economy of Flagstaff. The intersection of Indigenous religion with Flagstaff’s tourist economy, as well as environmental concerns, has made the Peaks a flashpoint for community conflict numerous times over the last half century. This dissertation explores the Hart Prairie Controversy, a conflict over use of the Peaks that began in 1969 when landowner and developer, Bruce Leadbetter, proposed a ski village to be located at Hart Prairie, just 1,000 feet of elevation below the base of the Arizona Snow Bowl. Leadbetter’s plans for a commercial and residential development to support thousands of tourists and newcomers alarmed neighboring landowners, local environmentalists, and Northern Arizona’s tribal nations, especially members of the Hopi and Navajo tribes. For almost a decade, Indigenous and non-Indigenous actors formed a loose coalition, sometimes working together, sometimes with differing aims, to oppose the Snow Bowl Village proposal through appearances at public hearings, statements in the local media, and when necessary, legal action. This dissertation shows the Hart Prairie Controversy as an example of a time when a confluence of social movements and increased legal and political access, especially among American Indians, coalesced to preserve unique spiritual and ecological ground from development and desecration.
