Greenspeed Anura in front of Jarboe's Store. Did I miss the going out of business sale?
This ruin is adjacent to the C&O Canal at the entrance to the parking lot that marks the location of Edwards Ferry* that once operated across the Potomac River between Virginia and Maryland.
The blurb on the nearby information panel reads:
The crumbling Jarboe's Store remains here today. It was a general store and post office operated by Eugene E. Jarboe in the late 19th and early 20th centuries. Flood damage in 1996 forced the National Park Service to partially tear down the unstable structure.
*Although the correct spelling should be "Edward's Ferry", This is one of those phrases that is usually spelled without an apostrophe.
