Tumamoc Hill, known in O’odham as Cemamagi Du’ag, Horned Lizard Mountain, is on the ancestral lands of the Sobaipuri and Tohono O’odham peoples. This volcanic hill is of prominent ancestral, cultural, and sacred significance to the O’odham nations, including the The Tohono O’odham Nation, Gila River Indian Community, the Salt River Pima-Maricopa Indian Community, and the Ak Chin Indian Community, as well as the Hopi Tribe and the Pascua Yaqui Tribe. The Desert Laboratory recognizes the cultural significance of Cemamagi Du’ag as the bedrock of our institution and our future actions.
