Book excerpt: "The subject matter of the San marcos Pass paintings is familiar. The simple geometrics--paralell lines, zigzaga, circles, dots, and grids--form the basis of art from the beginnings of human history. Some say these elements arise from experiences with altered states of consciousness. Deer, fish, birds, insects, amphibians, and humans appear in abstract and naturalistic forms. Others defy neat explanation." Description from the Introduction page 1.
