Writer Sunnie Empie and photographer Hart W. Empie reveal what it's like to live in the Boulder House, which was designed around an enormous outcrop of weathered granite that sheltered inhabitants from the Stone Age up to about 700 years ago. The text and about 150 color photographs describe the planning and building of the house as well as the Empies' appreciation of the high Sonoran Desert in Arizona, where ancient symbols carved into the rock connect the viewer to the cosmology of the first people in the American southwest.
