This is an American Indian ethnographic study for the Hoover Dam Bypass Project. The study sites included three bypass bridge alternatives, each located within one mile from where United States Highway 93 (U.S. 93), at the time of the study, crossed over the top of Hoover Dam at the Arizona-Nevada state line. Due to growth in population and commerce in the Southwest, the roadway at Hoover Dam has experienced a tremendous increase in traffic over the past 30 years, resulting in increased safety hazards to motorists, pedestrians, and the dam itself.

This ethnographic study was part of the environmental impact assessment for the Hoover Dam Bypass Project. Ten tribes participated in this study, including all eight Southern Paiute tribes and Hualapai tribe. This project focused on understanding traditional use and cultural connections to places within the proposed project boundaries. Ultimately, this work led to the successful two-state TCP nomination of Sugarloaf Mountain and Goldstrike Canyon in 2004.

In addition to the ethnographic reports produced for this collection, the following articles and book chapters were produced:
