I just discovered a walk about on Hashima Island in Japan.
This is a place where all the people left in 1974 when the coal mine closed.
It was once the most densely populated place on earth and now it crumbles.
Go back to a place where there were no cars and you could walk everywhere.
That is a very interesting question.
Maybe they took a guess based on the geology of the area and made some exploratory drill holes.
The area around may have had mines that were productive with seams leading to that island.
I wonder what it was like living there.
A great many of us are old enough to walk the streets of this place when it was a living town.
I think it would be one of those things you would grow up and miss when it was gone.
