(England) -- History buffs are celebrating a rare find in northwestern England. Members of a caving club discovered a "pristine" 200-year-old cobalt mine in the county of Cheshire. The site is thought to be abandoned in the early 19th century and came complete with a treasure trove of personal belongings left behind by the workers. Leather shoes, clay pipes, and mine machinery are just some of the objects discovered by researchers. One of the cavers who made the discovery called it "a compelling window into the past."
