Tales of secret underground laboratories abound in the lore of UFOs. But now there’s a real deep underground lab, and it’s no secret.  The Deep Underground Science and Engineering Lab(DUSEL) is being built in the old Homestake gold mine at Lead, South Dakota. There have been other labs built in the old mine in the past, particularly a neutrino detector, but until recently the mine was sealed and filling with water. The first efforts are to get the water out; other work will follow. The DUSEL will be at the 4850 level to start, with other labs planned as deep as 8000 feet.
