Johnstown
The Essential
Bountiful supplies of timber, oil and coal led to a booming steel industry in this pleasant village in a valley of the Allegheny Mountains. The health-care industry shoulders most of the local economy today, but the city is most famous for the devastating flood that swept down the valley in 1889, destroying Johnstown. Sights related to this catastrophe can be visited.
