Abstract: The US Congress codified the National Historic Preservation Act of 1966 (NHPA), the nation’s most effective cultural resources legislation to date, mostly through establishing the National Register of Historic Places (NRHP). The NHPA requires federal agencies to address their cultural resources, which are defined as any prehistoric or historic district, site, building, structure, or object. Section 110 of the NHPA requires federal agencies to inventory and evaluate their cultural resources, and Section 106 requires them to determine the effect of federal undertakings on those potentially eligible for the NRHP. Fort Riley is in north-central Kansas within Riley and Geary Counties. It consists of six functional areas, including the Main Post, Camp Funston, Marshall Army Airfield (MAAF), Camp Whitside, Camp Forsyth, and Custer Hill. This report provides a historic context for ranges, features, and buildings associated with the post’s training lands in support of Section 110 of the NHPA.
