For reasons unknown to us, the activity of creating rock art once flourished
on the Lower Susquehanna.
More than 1,000 carved images (petroglyphs)
of birds, animals, humans, the tracks that they make, and other more abstract designs have been documented on the rocks here.
The images offer us a precious glimpse of how these people who came to the river many generations ago saw their world. The
sites on the Susquehanna were perhaps the largest concentration of rock art in the northeast United States.
