Archaeology will be the focus of a program at the Manheim Historical Society this month. Adam Zurn, founder of Uncharted Lancaster, will present "The Mysterious Petroglyphs of Safe Harbor" on Sunday, July 21, at 2 p.m. The program will take place at the Manheim Railroad Station, 210 S. Charlotte St.

"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," Zurn said. "These 1,000-year-old rock carvings represent the oldest human-made artifacts in Lancaster County and one of the most significant archaeological sites in the northeastern United States. I will discuss their significance, possible meanings and some local legends surrounding the pictographs."

Zurn, a technology teacher at Lampeter-Strasburg High School, has a passion for history. His interest in the Safe Harbor petroglyphs began about five years ago when he started searching for a lost cemetery in Shenks Ferry, the site of tombstones dating to the 1700s.

"In my research to find the graveyard, I repeatedly read about the Shenks Ferry People - a previously unknown tribe of Native Americans first discovered in Shenks Ferry - who are believed to have created the Safe Harbor pictograms," Zurn explained. "The mystery and history etched into those rocks captivated me. I made it a point to locate these carvings by exploring the various rocks at Safe Harbor to find them. My adventures on the mighty Susquehanna have been a mix of thrilling exploration and detailed research. Today, I enjoy taking groups to see the ancient rock art in the summer." Zurn offers guided tours by kayak to the petroglyphs.

While searching for the Shenks Ferry cemetery, Zurn created Uncharted Lancaster. This passion project has evolved into an opportunity to uncover and share pieces of history in Lancaster County and throughout the Susquehanna Valley. "Through articles, photographs and guided adventures, I like to explore historical sites and stories, bringing them to light for everyone to enjoy," Zurn stated. "It's a platform for local history enthusiasts to connect, learn and engage with our regional heritage in a fun and interactive way."

Along with Zurn's talk, the Manheim Historical Society will be open from 1 to 4 p.m. on July 21 for tours of the railroad station and exhibits, a model train display and trolley rides, weather permitting.

Zurn said his presentation will be perfect for anyone with an interest in history, archaeology or Native American culture.

"I'll share fascinating stories, detailed images and insights that will leave viewers with a deeper appreciation for these ancient carvings hidden on the border of Lancaster County and the people who created them," he said. "It's a chance to connect with our past in a meaningful and engaging way."

He also hopes his program will spark an interest in learning more.

"I would like people to know that this presentation is just the beginning," he said. "There are many more hidden gems and historical mysteries in Lancaster County that I plan to explore and share through Uncharted Lancaster. I hope this program inspires others to embark on their own adventures and discover the rich history that surrounds us."
