In The Rocky Mountains I crawled down a cliff at 10000 feet above sea level to get to a ghost town called Gilman. Abandoned in 1984 through a forced evacuation by the EPA, the water and soil were so contaminated the entire site is still off limits to the public today.
Once home to 300+ people, the town site had a bowling alley, schoolhouse, grocery store and even their own newspaper. The hospital took hundreds of x-rays of the miners, trying to detect lead and zinc poisoning. Now the complex is filled with scattered prints of skulls and hands of the former residents. Gilman was one of the most interesting and beautiful places I've ever trespassed, but I definitely don't plan on returning.
