Despite the groundwater being hopelessly toxic, the Janesville Old Landfill, better known as "The Pit", has much to offer for an unorthodox urban hiker. The landscape is twisted in an otherworldly style, and there are limitless opportunities to find things that you don't see everyday, from cold war era soda cans to propane tanks from bygone eras, mysterious buildings whose purpose has been subject to much debate, and a pond that supports a healthy goose population and enormous carp. To get down to the landfill is a task: it's not called "The Pit" for nothing. It is flanked by >100 foot cliffs on all sides, the slope of which being about 45 degrees. Considering this, the pit is not for the faint of heart. Be warned.
