About

Hanging Rock, also known as "Overhanging Rock", "Gulph Rock," and "Drummond's Head", is a natural geologic feature in Gulph Mills, Upper Merion Township, Montgomery County, Pennsylvania. The outcropping of phyllite is the remnant of a natural arch eroded by Gulph Creek, that collapsed millennia ago.

The rock has long been associated with General George Washington and the Continental Army's December 1777 March to Valley Forge.
