Kennecott, Alaska
Kennecott, Alaska was known for having about $200 million worth of copper processed there. However, the place has been abandoned for over 60 years and most of its buildings have deteriorated completely, but still remain an interesting sight to see. The National Park Service purchased many of the buildings in 1998.
Bodie, California
While it may look like a set of Westworld, the now-abandoned town of Bodie, California was once booming. It housed 10,000 people in the 1870s and 1880s during the gold rush around Mono Lake. It has since become a State Historic Park. It can be found in a state of “arrested decay,” meaning everything remains as it was.
