 The Seneca tribe of the Iroquois believed that Pine Creek Gorge was sacred land and never established a permanent settlement there.They used the path through the gorge and had seasonal hunting camps along it, including one just north of the park near what would later be the village of Ansonia.To fill the void left by the demise of the Susquehannocks, the Iroquois encouraged displaced tribes from the east to settle in the West Branch watershed, including the Shawnee and Lenape (or Delaware).
