Tragedy at Crow Rock

It was a picturesque morning in May. The trees were green, the flowers were in bloom, and it was as beautiful as a Greene County spring morning can be, with the sun shining and the weather perfect. The four Crow sisters—Lisbeth, Susie, Katie, and Tena—were on their way to visit sick neighbors.

World-Famous Boundary Line

When it comes to taking its place in American history, Greene County is unparalleled. And it’s because of a parallel of latitude that Pennsylvania’s southwestern-most county stands above all others. The famous Mason-Dixon Line, run from 1763-67 by British astronomers and surveyors Charles Mason and Jeremiah Dixon, ends its journey at the edge of Greene County.
