April 18: Mysterious Petroglyphs of Safe Harbor Presentation & Book of Secrets Adventure Kick-Off

Join me at the Milanof-Schock Public Library in Mount Joy for an exciting double-header event on Monday, April 18, 2022.

The Mysterious Petroglyphs of Safe Harbor Presentation

At 6 pm, I will be recounting my expeditions down the lower Susquehanna to explore the mysterious Native American petroglyphs hidden on the ancient river at Safe Harbor. These 1,000 years old rock carvings represent the oldest man-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 share some local legends surrounding the pictographs.

This in-person program is free and open to the public.
