The Sewickley Caves: Illuminating the Darkness

Written by Dennison Daniel Moore and William L. Moore, Jr., this book was published in 2010 in cooperation with the Sewickley Valley Historical Society. It is a charming illustrated history of the caves beneath Sewickley Cemetery and across the Ohio River in Coraopolis, most of which are now inaccessible.
