Starting with the documentation of the petroglyphs in the 1800s up to present day we learned about the differences of the rock art at these three locations as well as more detailed description of those at Safe Harbor. Paul Niven has been researching the petroglyphs on the lower Susquehanna River for over forty years. He guides tours to view the rock art for Safe Harbor Petroglyphs Tours and has recently published a guidebook book about the petroglyphs.
