Description

Spiral Jetty is an earthwork sculpture by Robert Smithson, consisting of a 1,500‑foot (460 meter) long, 15-foot (4.6 meter) wide anticlockwise coil jutting from the northeastern shore of the Great Salt Lake in Utah, USA. Smithson reportedly chose this site because of the vibrant colors of the water (salt‑tolerant bacteria and algae thrive here in water with 27% salinity) and its similarity to the Earth’s ancient seas.
