The Spiral Jetty was created by an artist out in the Utah desert in the 1970s. It is sometimes visible and sometimes submerged, depending upon the water level of the Great Salt Lake.
I quite like this overhead, aerial view. It shows a mix of warm and cool colors and competing textures. And if you look closely, you can see little dots, which are people walking around and exploring the feature.
Here’s a zoom in to see the detail and textures better.
