I made a day trip to visit Robert Smithson's 1970 earthwork sculpture, Spiral Jetty. The jetty is sometimes fully exposed. During my visit it was partially submerged in water. See link for more images.
My friends told me Spiral Jetty was down a rough narrow road, a little hard to find, with four-wheel drive highly recommended. Exciting! However, some folks have decided to "improve" the site, extending the gravel road all the way to the end and plonking a large car park literally a hundred feet from the sculpture. eliminating any sense of discovery. Smithson would have hated this. Why do institutions have to sanitize everything?
