Solstice Clock 1999 was created by Schmidt Design Group and Paul Hobson Nature’s Bridge to Discovery. Twice a year, during the summer and winter solstices, a circle of benches form a solstice clock stamped with the words “Time,” The openings in the benches line up with some patterns in the concrete that point to where the sun sets on the winter and summer solstice., says Glen Schmidt, president of Schmidt Design Group. He calls the installation a “mini Stonehenge". “Continuance,” and “Change.”
