This spiral petroglyph is one of the pieces of prehistoric art on display along the pathway through the rock garden.  Brethauer has a theory that the number of circles within the spiral is related to the number of families that had lived within the ancient associated settlement.  If the rock with the spiral had been placed near an ancient dwelling, then the number of circles signified the number of people within the family.
   I had not heard or read about this idea before.  Maybe Gus is on to something!
