Irwin Run

Irwin Run is a scenic and high-gradient tributary known for its dramatic rocky gorge and a beautiful, tiered waterfall. The run drops over several sandstone ledges as it carves its way through the plateau toward the Clarion River. The area around the falls is carpeted in thick mosses and liverworts, thriving in the cool, constant mist. It is a preferred destination for adventurous photographers and hikers who enjoy the challenge of navigating the steep, unmarked terrain to find one of the forest's most intimate and hidden water features.
