The most notable feature in the park is Chickies Rock, a massive outcropping of quartzite rock towering 200 feet above the river. The vista offers impressive views of York County, the borough of Marietta, and farmlands of northwestern Lancaster County. Chickies Rock Park is also a collection of historical treasures. The area once boasted seven iron furnaces and rolling mills, a canal and a local trolley line. Remnants of several furnaces, canal walls, and trolley-line grades are still visible.
