After reading through this article, I immediately went to google maps to see if they had any street-level views of the town. Thankfully, they do. From them, and the satellite views, you can see both the chat (I'm guessing that's what those large-ish white mounds are -- I could be wrong) mentioned in the article and "explore" the mostly abandoned town.
Impressive. In Missouri, St. Joe Lead Co. donated land containing its mountains of tailings for a state park. St. Joe's State Park, popular for off-roading, with people riding their ATVs, minibikes, etc. through the tailings from the lead mines, also happens to be part of a Superfund site, but that doesn't dissuade people.
