Based on the author's Masters thesis in anthropology at the University of California Santa Barbara, the book presents photographs of most of the known rock art sites in the Santa Ynez Mountains behind Santa Barbara, California. Most rock art books concentrate on spectacular sites and ignore the full range of art in a region, Hyder explores the range of Chumash rock paintings in his photographs primarily shot from 1979-1981. Originally published in 2002 as a hand made portfolio book limited to 13 copies.
