Spiral Jetty
by Robert Smithson
For nearly three decades Robert Smithson's "Spiral Jetty" lay underwater in the Great Salt Lake. Since 1999, as drought has lowered the water level, this famous American earth sculpture — a 1,500-foot coil of black basalt rocks — has slowly re-emerged. Now it is completely exposed; the rocks encrusted with white salt crystals are surrounded by shallow pink water in what looks like a vast snow field.
