Robert Smithson’s Spiral Jetty (1970) is a site-specific sculpture that is located at Rozel Point on the northeastern shore of the Great Salt Lake. Made of black basalt rocks, salt crystals, earth, and water, Spiral Jetty is a 1,500-foot-long coil, measuring approximately 15 feet wide, that stretches into the lake. The fractured rocky landscape and changing water levels of the Great Salt Lake appealed to Smithson’s interest in entropy, where the forces of nature can change the work at any moment in time.
As stewards of Spiral Jetty, Dia is committed to recording changes to the work over time through photographic documentation. Since 2012, a geospatial aerial photographer has documented Spiral Jetty twice a year, in May and October.
