Grey Crawford created his series El Mirage from 1975-78, in the Mojave Desert in California. The photographs feature configurations that were constructed from a contrast of materials, glass, steel and aluminum sheets, combined together to pull upon their sheer weight and balance to expose their natural vulnerabilities. El Mirage reflects upon the artist's interaction with nature and embodies the spirit of performance and land art during the 1970s. These unseen photographs from 40 years ago are being published for the first time.

Besides the black-and-white photos that Crawford is famous for, this volume also contains color photography, an introduction by Timothy Persons, and an essay by Lyle Rexer.
