An eccentric inventor who formulated the process to create Calcium Carbide, a powerful industrial chemical, built a rather lavish and remote laboratory "summer home" in the woods of Ontario Canada in 1907. Some say he moved out there to enjoy nature, others say it was out of a paranoid fear of industrial spies and saboteurs seeking to undermine his efforts and steal his research. Whatever the reason he built it, he wound up losing his estate to his creditors when his arc lamp inventions failed to keep up with his expenses, and he died in 1915 of a heart attack. The estate was passed to his creditors in America, and due to the remote location and international affairs dealing with the property, it was left to ruins. In the following years, the entire area was swallowed up by the Canadian Government and transformed into what is now Gatineau Park. The ruins of "Carbide Wilson's" laboratory and the scenic areas around it are now spots for hikers to get some cool photos- like these.
