This gentleman, photographed in 1922, peers at one of the 36 boundary stones that trace the edges of the District of Columbia.
A team of surveyors led by Major Andrew Ellicott erected this marker in 1792 to show the northwest boundary line of the District of Columbia. It is one of 36 boundary stones that the surveyors placed—one mile apart—along each side of the diamond-shaped district that they were carving out of Maryland and Virginia.
The stone rests within the fenced Dalecarlia Water Treatment Plant grounds, 100+ feet east of the Capital Crescent Trail (from the “Entering Montgomery County” sign) and several hundred feet north of the intersection of Norton Street and Potomac Avenue. The easiest way to see this stone is through the fence along the Capital Crescent Trail.
