Discover DC Boundary Stones in Maryland-NW Stone 4 to North Corner Stone
Details
This is the third hike along the original boundary line between the nation’s capital, Virginia, and Maryland. See stones placed every mile along the boundary survey line in 1792. These stones are the first federal monuments in the nation’s capital.
Initially, we will hike a short distance along the Capital Crescent Trail to view NW Stone 4, which is on Delcarlia Reservoir grounds. We will come back to our meeting location and hike north along Norton Street and Loughboro Road (restroom opportunity at Sibley Hospital) to Delcarlia Parkway. We will hike a short distance along Delcarlia Parkway and then on Spring Valley neighborhood streets to Warren Place and Delcarlia Parkway, where we will get you as close as we can to the location of NW Stone 5, which is also on Delcarlia Reservoir grounds. We will hike Spring Valley neighborhood streets to Massachusetts Avenue and Western Avenue at Westmorland Circle, and then on sidewalks along Western Avenue (NW stones 6, 7, and 8 are in front yards along Western Avenue), on trails through the northern portion of Rock Creek Park(NW 9 is adjacent to the park), and on sidewalks along streets in Silver Spring (North corner stone is just south of East-West Highway, west of 16th Street) to the Silver Spring Metro Station. Total distance is approximately 10.5 miles.
We will meet 9:30 am, Thursday, February 26, 2026, at the connector trail to the Capital Crescent Trail (Norton Street and Potomac Avenue NW).
