I thought you’d appreciate this postcard since Smithson forgot to build a gift shop on his jetty. His friend Richard said the original design featured just a single hook-like bend out in the lake until someone with gestalty imagination asked: do you intend to build a 7,000-ton question mark? So he went spiral. Were the rocks all salt crystalled when you went? Were you tempted to pocket a souvenir? I don’t know why I love that alternating boundary of rock/salt/lake/salt/rock/salt/lake/salt… so much. Maybe it activates that part of our animal brain drawn to salt licks.
