Scattered throughout Eastern Pennsylvania are remnants of history being reclaimed by nature. Join author and photographer Kathleen Butler on a journey to discover the little-known history of ruins deep in the woods of Pennsylvania that can only be reached by foot. Venture along and unearth remnants of the coal mining industry, mills, railroads, and more. Explore the history that is not taught in schools. Those who only live a few miles from these ruins do not know of their existence, let alone their past. Some are from industries that fell hard when the market was no longer in their favor. They ultimately abandoned their businesses or moved elsewhere. Others tried to establish themselves only to find that the area was not suitable, thus leaving their failed community behind. Soon, these abandoned ruins will disappear into the forests of Pennsylvania forever.
