Guinn Run

Guinn Run is a Pennsylvania stream flowing southeastward in the Gettysburg National Military Park from Cemetery Hill past the Gettysburg Museum and Visitor Center to Rock Creek (Monocacy River). The stream was bridged by the 1809 Gettysburg and Petersburg Turnpike Company and in the commerative era by the United States War Department when Hunt and Slocum Avenues were built. A dam was built on Guinn Run to form a pond for Fantasyland, Pennsylvania, through the 1960s and 1970s.[1]
