The Kinzua Skywalk comes with significant history. It was once the tallest railroad structure at 2,053 feet long and 301 feet high until partially destroyed by a tornado in 2003. In 2011 it was reinvented and turned into a skywalk. Now, photographer Gladys Caroline invites you to see what was once known as Pennsylvania’s eighth wonder of the world through her eyes. *This book is in paperback with standard color and printing at an affordable price.
