Rock Run Mill

The Conowingo Dam
The hike was about 3 miles in each direction, from the Rock Run Mill to the Conowingo dam and back. The path started along an abandoned rail bed with tracks still rusting and ties rotting in place. Then along a riverside trail and back up onto a graveled rail bed without the old rails and ties. The rail bed was originally an early 19th century canal tow path that was converted to a railroad in the early 20th century and used to carry equipment and materials to the construction site of the Conowingo dam. It was a beautiful day for hiking. More photos can be seen here.
