I recently saw an interesting article on the current drought in the Midwest.
It was an NBC news story on how reseeding water levels have unearth some buried ghost towns.
This story gave me a new look at what our dams and made made lakes have subsequently buried all over the country....
One of the most interesting cases was of Monument City Indiana. It was relocated after the Salamonie river was dammed up in early 1960s.
The Indiana state department of recreation created a guided tour found here. and the Wikipedia entry gives some background info, found here.
