The Susquehanna River petroglyph's are estimated to be between 800 and 1,000 years old carved by the Native American Tribes that inhabited this area long before the first Europeans arrived in the 1600's. They used nothing but stone tools to make the carvings. The petroglyphs are from a time when Central Pennsylvania was a wilderness inhabited only by tribes of Native Americans and bountiful wildlife. Worn by time and water they tell a long forgotten story.
