Formerly located along Southern Avenue a few feet southeast of the intersection with Naylor Road (and not at the intersection of Naylor Road and Suitland Parkway, as some sources state). Nothing remains to mark this stone--not even a plaque. The stone is not lost, however. David R. Doyle of Silver Spring, MD, has had it in his garage since 1991. Mr. Doyle explains, "SE 4 is in my possession. The stone was recovered some years ago by volunteers from the Maryland Society of Surveyors (MSS) working on a resurvey of the DC line. As an employee of the National Geodetic Survey (NGS), a member of MSS and the District of Columbia Association of Land Surveyors (DCALS) and the geodetic survey liaison for the City of Washington it was felt that I was in the best position to ultimately coordinate having this mark reset on-line as close to its original location as possible."
