Dan, Your question forces me to expose the truth about this earthwork. Most people believe that the jetty was designed as a spiral, but that's not so. It was built straight as an arrow to draw the eye out to the horizon and cause an observer to feel awed by the "vast expanse" of the lake. Naturally, it was called "Straight Jetty." The brine flies were upset that their habitat was disturbed by the "artwork" and re-arranged the rocks to form a spiral, thereby thwarting the artist's intentions and rendering the construction meaningless. The artistic community, embarrassed by this turn of events, renamed the thing "Spiral Jetty" and hoped that the public wouldn't notice. I hope you didn't get wound up by this explanation.
