Boundary markers of the original District of Columbia

File:Chart showing the original boundary milestones of the District of Columbia LOC 87694134.jpg

The District of Columbia (initially, the Territory of Columbia) was originally specified to be a square {{convert|100|sqmi|km2}} in area, with the axes between the corners of the square running north-south and east-west, The square had its southern corner at the southern tip of Jones Point in Alexandria, Virginia, at the confluence of the Potomac River and Hunting Creek (later the site of the Jones Point Lighthouse).{{cite book|url=http://babel.hathitrust.org/cgi/pt?id=mdp.39015013259695;view=1up;seq=5|last=National Capital Planning Commission|year=1976|title=Boundary markers of the Nation's Capital: a proposal for their preservation & protection: a National Capital Planning Commission Bicentennial report|place=Washington, D.C.|publisher=National Capital Planning Commission; For sale by the Superintendent of Documents, United States Government Printing Office|oclc=3772302|access-date=2016-02-22|via=HathiTrust Digital Library}} The sides of the square were each {{convert|10|mi|km}} long. The specified orientation results in a diamond shape for the District's original boundaries on most maps.

The north-south axis of the District's current boundaries extends southward from the District's north corner near East-West Highway (Maryland Route 410), travels between 17th and 18th Streets, N.W., and continues south across the National Mall to the far shore of the Potomac River; the east-west axis is between the present Constitution Avenue and C Street, N.E. and N.W.The north-south axis is a straight line connecting the north and south cornerstones of the original District of Columbia. The east-west axis is a straight line connecting the east and west cornerstones of the original District of Columbia.

These axes are not the lines used to define the four geographical quadrants of the District (N.E., N.W., S.E., and S.W.), commonly appended to Washington street addresses, which are delimited generally by North Capitol Street, East Capitol Street, South Capitol Street, and the National Mall. The center of the square is west of the Ellipse and north of the Mall, within the grounds of the headquarters of the Organization of American States.Coordinates of the center of the square of the original District of Columbia: {{coord|38.893098|-77.040799|format=dms|type:landmark_region:US-DC|name=Center of the square of the original District of Columbia}} The center of the square of the original District of Columbia is the crossing of the north-south axis line and the east-west axis line.

In 2011, the District of Columbia geographic information system (GIS) program completed a project to map the District's boundary using Global Positioning System (GPS) and contemporary survey technology at an accuracy of ±{{convert|5|cm|in|1}} horizontally and ±{{convert|9|cm|in|1}} vertically. The GIS program's survey found that (listed in the order in which Andrew Ellicott's team performed the initial boundary survey):

• Along the northwest boundary, the stones are outside the existing boundary ranging from {{convert|4.43|ft|m|2}} to {{convert|9.6|ft|m|2}}
• Along the northeast boundary, the stones are inside the existing boundary ranging from {{convert|6.6|ft|m|2}} to {{convert|8.4|ft|m|2}}
• Along the southeast boundary, the stones are outside the existing boundary ranging from {{convert|12.75|ft|m|2}} to {{convert|18.48|ft|m|2}}

The overall accuracy of the historic survey and the survey using 2011 technology produced remarkably similar results. For example, the distance between Southeast stones numbers 6 and 7 is {{convert|5,280.824|ft|m|4}}, almost exactly one mile ({{convert|5,280|ft|m|4}}).{{cite web |url=https://octo.dc.gov/release/historic-review-district%e2%80%99s-boundary-stones-using-gps-and-modern-survey-technology|title=Historic Review of the District's Boundary Stones Using GPS and Modern Survey Technology: Accurately mapping the District of Columbia boundary for the DC GIS|website=Office of the Chief Technology Officer: Government of the District of Columbia (DC.gov)|date=November 1, 2011|access-date=October 11, 2017|archive-url=https://web.archive.org/web/20171011190244/https://octo.dc.gov/release/historic-review-district%e2%80%99s-boundary-stones-using-gps-and-modern-survey-technology|archive-date=October 11, 2017|df=mdy-all}}

The stones are located alongside streets, in public parks, deep in the woods and on personal property. Homeowners with stones on their property are generally willing to let the curious take a closer look if they are respectful.{{Cite web|url=https://wtop.com/dc/2018/04/boundary-stones-the-quest-to-save-dcs-history/|title=Boundary Stones: The quest to save DC's 1st federal monuments|date=2018-04-10|website=WTOP|language=en|access-date=2019-09-16}}

On March 30, 1791, President George Washington issued a proclamation that established ″Jones's point, the upper cape of Hunting Creek in Virginia″ as the starting point for the federal territory's boundary survey.{{cite book|last=Washington|first=George|url=https://books.google.com/books?id=qhk_AQAAMAAJ&pg=PA254|section=Proclamation: Georgetown, March 30, 1791|title=The Writings of George Washington from the Original Manuscript Sources: 1745-1799|year=1792|editor=John C.

The survey team then cleared a corridor along the boundary route to facilitate surveying, traveling clockwise from the point and placing sandstone boundary markers at the four corners and at intervals of approximately one mile. The markers were quarried near Aquia Creek in Virginia. Most weighed about a half-ton at their emplacement; the four cornerstones were slightly larger. The Virginia stones were set in 1791, and the Maryland ones in 1792. The map on the web page "Boundary Stones of the District of Columbia" identifies the location of each of the four corner stones, and those of the still-in-place intermediate stones.{{cite web|url=http://www.boundarystones.org|title=Boundary Stones of the District of Columbia|access-date=2018-11-18}}

The side of a boundary marker that faced the federal territory was inscribed "Jurisdiction of the United States" and with the distance in miles and poles from the previous corner stone. The opposite side was marked with the name of the border state: Virginia or Maryland. The remaining sides were marked with the year that the team placed the stones and with the variation ("Var.") of the compass needle at that place.{{cite book|url=https://archive.org/details/bub_gb_D_ZJBxoCYeAC_2|title=Standard History of the City of Washington From a Study of the Original Sources|pages=[https://archive.org/details/bub_gb_D_ZJBxoCYeAC_2/page/n158 150]–151|last=Tindall|first=William|location=Knoxville, Tennessee|publisher=H.

On January 1, 1793, Andrew Ellicott submitted to the commissioners a report that stated that the boundary survey had been completed and that all of the boundary marker stones had been set in place. Ellicott's report described the marker stones and contained a map that showed the boundaries and topographical features of the Territory of Columbia. The map identified the locations within the Territory of the planned City of Washington and its major streets, as well as the location of each boundary marker stone.(1) {{cite journal|url=https://books.google.com/books?id=GgULOzNSafMC&pg=PA57|last=Steward|first=John|year=1898|title=Early Maps and Surveyors of the City of Washington, D.C.|journal=Records of the Columbia Historical Society|volume=2|page=57|oclc=40326234|location=Washington, D.C.|publisher=Columbia Historical Society|via=Google Books}}

In 1906, Fred E. Woodward read a paper to the Columbia Historical Society that described the history, location and conditions of each of the remaining boundary stones, together with photographs of each. His paper concluded by recommending that the stones be protected by placing small fences around each one.{{cite journal|last=Woodward|first=Fred E.|url=https://books.google.com/books?id=p7PJmNmjRgoC&pg=PA63|title=A Ramble Along the Boundary Stones of the District of Columbia with a Camera|pages=63–87|journal=Records of the Columbia Historical Society Society|year=1907|volume=10|publisher=Columbia Historical Society|location=Washington, D.C.|access-date=2016-10-08}} In 1909, Ernest A. Shuster of the United States Geological Survey wrote an article for the National Geographic Magazine that described his visits to the 36 remaining boundary stones and that urged their protection and preservation.{{cite journal |last=Schuster |first=Ernest A. Jr.|url=https://books.google.com/books?id=jY9-AAAAMAAJ&pg=PA356|title=The Original Boundary Stones of the District of Columbia|journal=National Geographic Magazine|editor=Gilbert H. Grosvenor|pages=356–359|volume=20|year=1909|location=Washington, D.C.|publisher=National Geographic Society|access-date=2016-10-08}}

In 1915, various local chapters of the Daughters of the American Revolution (DAR) began to place fences around each of the markers. The DAR also placed at the exact center of the original federal territory a marker stone that was located about a half of a mile from the White House and was near the DAR's Memorial Continental Hall.

One Virginia boundary marker was added to the National Register of Historic Places in 1976, and another in 1980. In 1991, the remaining Virginia boundary markers were added to the National Register in response to a Multiple Property Submission that the Virginia DAR had submitted.{{Multiref2

In 1976, the National Capital Planning Commission published a report that described the history and condition of each boundary stone. The report recommended that measures be taken to assure the stones' preservation. In 1990 and 1991, a resurveying team to celebrate the boundary markers' bicentennial located two of the then-missing stones.

In 1995, the Northern Virginia Boundary Stones Committee, whose establishment the Northern Virginia Regional Commission (NVRC) had requested, issued a list of recommendations intended to document and preserve the 14 boundary stones that were located in Virginia. The Committee included representatives of the State of Maryland and of Arlington and Fairfax counties and the cities of Alexandria and Falls Church in Virginia.{{Multiref2

In 2008, the NVRC announced that four Virginia local governments, including Arlington and Fairfax counties and the cities of Alexandria and Falls Church, had agreed to help fund a project to protect and preserve the boundary stones by providing matching funds to a Transportation Enhancement Grant that the District Department of Transportation (DDOT) had received from the Federal Highway Administration (FHA). The announcement stated that the NVRC was working on an agreement with the DDOT, the National Park Service and the FHA to administer the project.{{cite web |url=https://www.novaregion.org/Archive.aspx?ysnExecuteSearch=1&txtKeywords=Preserve+DC+Boundary+Markers&lngArchiveMasterID=0&txtDateRange=&dtiStartDate=08%2F14%2F2008&dtiEndDate=08%2F15%2F2008 |title=Northern Virginia Regional Commission Leads Project to Preserve DC Boundary Markers |publisher=Northern Virginia Regional Commission |date=2008-08-14 |work=News Release |access-date=2011-11-19 |archive-url=https://web.archive.org/web/20181119020528/https://www.novaregion.org/Archive.aspx?ysnExecuteSearch=1&txtKeywords=Preserve+DC+Boundary+Markers&lngArchiveMasterID=0&txtDateRange=&dtiStartDate=08%2F14%2F2008&dtiEndDate=08%2F15%2F2008 |archive-date=2018-11-19 }}

The comment stated: "Stones laid by Benjamin Banneker in the 1790s are still standing". Actually: Ellicott, a prominent professional surveyor, hired Benjamin Banneker, an astronomer and mathematician from Maryland, to make the astronomical observations and calculations necessary to establish the south corner of the square at Jones Point in Alexandria. According to legend, "Banneker fixed the position of the first stone by lying on his back to find the exact starting point for the survey ... and plotting six stars as they crossed his spot at a particular time of night." From there, Ellicott's team (minus Banneker, who worked only on the south corner) embarked on a forty mile journey, surveying ten-mile lines first to the northwest, then the northeast, next southeast, and finally southwest back toward the starting point, clearing twenty feet of land on each side of the boundary. The comment cited http://www.boundarystones.org as the source of its information.}} As part of the project, in January 2015 a DDOT crew unearthed a stone buried in 1962 that had replaced Southeast No. 8, with the intention of cleaning and restoring the marker.{{cite web|url=http://www.nbcwashington.com/video/#!/news/local/History-Unearthed--Boundary-Stones-of-D-C-/290142041|last=Sherwood|first=Tom|title=History Unearthed: Boundary Stones of D.C.|publisher=NBC 4 Washington, D.C.|format=video|date=January 28, 2015|access-date=March 31, 2016}} However, in 2016, the stone was replaced by a new stone that presumably replicated the appearance of the original stone when the original was new.{{cite web|archive-url=https://web.archive.org/web/20161015145159/http://boundarystones.org/view.php?stone=SE8|archive-date=October 15, 2016|url=http://www.boundarystones.org/view.php?stone=SE8|title=SE8 (with 2016 photograph of new replica stone)|work=Boundary Stones of the District of Columbia|publisher=boundary stones.org|access-date=January 29, 2017}}
