The story of Triangle

Pennsylvania invented the American company town — coal patches and oil booms that burned bright and short.

The Erie Triangle is a roughly 300-square-mile (780-square-kilometre) tract of land that was the subject of several competing colonial-era claims. It was eventually acquired by the U.S. federal government and sold to Pennsylvania so that the state would have access to a freshwater port on Lake Erie. The Erie Triangle land makes up a large portion of present-day Erie County, Pennsylvania.
