On the way to the Jetty from Golden Spike there's roughly a 20-mile drive on washboard road surrounded by beautiful mountainous desert landscape. There we encountered wild horses (mustangs) crossing our path. Horses can represent wild freedom, free expression, gentle grace and beauty. They are powerful, free and wild. They are also a problem because they reproduce too fast, have no predators, and overgraze among other issues.
When we finally reached Spiral Jetty, it was surprising to see so many other people there. There were at least three or four other cars parked, and we passed people leaving as we were approaching. Definitely off the beaten path. Fortunately (depending on your perspective), the lake water was low, the Jetty is not always visible depending on water level. After walking the spiral, we walked another half mile across the white salt desert to the edge of the lake. Felt like being on a different planet.
Definitely a worthwhile pilgrimage, the horses made it more magical.
