The settlers of Iosepa, in addition to leaving a well-kept cemetery, also left their mark on the area at Story Rock. The rock, a large boulder, sits alone on Salt Mountain. The Iosepa settlers carved petroglyphs into the rock, presumably, to tell a story of their roots in Polynesia.

Though not old by most standards (carved after 1889), the petroglyphs hold a mesmerizing mystique. Unique to any others in Utah, the symbols are fascinating to see and leaving the viewer pondering the story the artists were trying convey.
