THE UNION (GRASS VALLEY) -- Noxon and Marcus were first exposed to Native American paintings and carvings in Zion National Park in 1975. Intrigued, they sought scholarly information about these enigmatic images. To their dismay, the professionals did not regard rock art as a cultural resource worth studying.
This realization motivated them to document rock art so it could be studied as a legitimate cultural and archaeological resource. Armed with a grant from the National Endowment for the Humanities and sponsorship from the San Francisco State University Anthropology Department, they began a new career.
