Photos: Spiral Jetty, Robert Smithson's wondrous earthwork

A low angle look at Spiral Jetty from in front, just off the north shore of the Great Salt Lake.

Robert Smithson, the artist who created Spiral Jetty, died in 1973, just three years after the earthwork was installed. Today it is managed by the Dia Art Foundation.
