It belongs to a rare surviving group of boundary markers tied to the development of the federal city. Criteria Consideration B applies because it was moved about 44.90 feet from its original position.","narrative":"This Aquia sandstone marker is the fifth mile stone on the southwest side of the original District of Columbia boundary, set five miles from the South Cornerstone at Jones Point. It sits among hardwood trees on the line between Arlington County and the city of Alexandria, Virginia, and both jurisdictions own it. Regrading of Route 7 forced its move of about 44.90 feet from its first position near a creek. Only a stub remains, broken about a foot above ground; surveys in 1894-97 and 1906 already recorded the top as missing. In 1921 the Keystone Chapter of the Daughters of the American Revolution placed a white-painted wrought iron fence around it, with a bronze plaque identifying the original federal boundary stone of 1791-1792. The marker was listed for its link to the planning and development of the federal city and as part of a rare group of surviving boundary stones. Its relocation was accepted as an exception.","period_of_significance":"1791-1921","architect_builder":"Unknown","architectural_style":null,"criteria":["A"],"status_note":"The stone is broken off about one foot above ground, with the top missing since early surveys.
