Southeast No. 9 Boundary Marker of the Original District of Columbia

.225 mi. S of Oxon Cove Br. and 420 ft. E of Shepherd Pkwy., Washington, District of Columbia


File:SE 9 1907.tiff

Boundary stone SE 9 marking the borders of the District of Columbia. This is one of 40 original stones, the one furthest south in the current district. In 1907 it was essentially IN the Potomac River. Today it is located some distance NE of its original location to save it from being lost to the Potomac River.
