If I'm channel surfing, and I come across a Science Channel, History Cahnnel, or Discovery Channel show about dams, I invariable stop and linger for a while. They are amazing structures, and thinking about the force one of these holds back is awe inspiring.
This is the dam that made Lake Wallenpaupack happen. Do yourself a favor. Do a Google search and read about the lake's beginning, and how the whole thing came about. There's a lot of history under water in Wayne and Pike counties.
