This is the Spiral Jetty. It's a piece of landscape art that was constructed in 1970 (I believe....but I've been wrong before; nope, I'm right. CHECK IT.). It lives in the Great Salt Lake in the great state of Utah. The spiral itself is pretty great - though it serves no purpose, other than looking great. In high-water years, it is flooded out of sight by rising water and other times, when the water level of the lake is low enough, the rocks that comprise the Jetty are seen sitting plainly in the salty bed of the lake. It smells horrible out here, by the way.
For this picture, I was lucky enough to show up when the water was glassed-over and pooling within the entire spiral. Special, right? Appreciate it.
