Interesting link, via Japundit, about an island off of Japan (near Nagasaki) that was a mining town from approx. 1930 - 1974. At the time, it had more people per square mile then any island in the world. The people worked in mines on the island.
In 1974, the mine pulled out and so did the people; some even left behind personal articles. A Japanese photographer went to the island recently and took some beautiful pictures. Check it out.
Also, check out the photographers page. There are some hauntingly beautiful pictures there.
