In response to possible damages to cultural resources incurred by a utilities installation project, in Tempe, Arizona, Logan Simpson completed a joint archaeological and ethnographic study of Nanakmel Kii/Qmpanyk Nyiva (Bell Butte). Bell Butte is a Traditional Cultural Property (TCP) among the Akimel O’Odham (Pima) and Piipaash (Maricopa) communities of southern Arizona. Incorporation of both archaeological and traditional perspectives yielded significant and unprecedented insights into the material and memory culture of the butte. Specifically, reexamination of rock art atop the butte along with objects recovered from a ceremonial cave clearly establishes O’Odham and Piipaash affiliations with the butte and the role of O’Odham songs in perpetuating the memory culture of this sacred place. Using these insights, Logan Simpson and the City of Tempe developed land-management practices intended to preserve and protect the sacred butte from further desecration and advance the repatriation of sacred objects recovered from a cave at the butte to the Akimel O’Odham.
