Check out this remarkable drone video of a famous sculpture built into the shores of the Great Salt Lake, Utah, compliments of contributor and pilot Dewey_Drone. The Spiral Jetty was built by an American sculptor named Robert Smithson. Completed in 1970, the unusual landmark spans a lenth of over 450 meters (about 1.5k ft.). Its construction was documented in a film produced by the Smithsonian. The Spiral Jetty is situated on the shore of the lake, the largest salt lake in the Western Hemisphere.
