I will recount my expeditions down the Lower Susquehanna to explore the mysterious Native American petroglyphs hidden on the ancient river at Safe Harbor. These 1,000-year-old rock carvings represent the oldest human-made artifacts in Lancaster County and one of the most significant archeological sites in the northeastern United States. I will discuss their significance, possible meanings, and some local legends surrounding the pictographs.
This in-person program is free and open to the public, but pre-registration is required. Click here to RSVP. It is perfect for adults and older children who love to explore or enjoy local history. Iโll be handing out free Uncharted Lancaster stickers and magnets to attendees, plus replica arrowheads for the kids.
I will also have signed copies of my books for sale, including Ghosts, Monsters, and Tales of Adventure,ย Uncharted Lancaster:ย Fieldย Guide to the Strange, Storied, and Hidden Places of Lancaster County, Pennsylvania, and Canassatego and His Six Arrows. I will be donating 50 percent of all proceeds from sales that night to the Historic Preservation Trust of Lancaster County.
Donโt miss out. I hope to see you there!
