• DC Boundary Stones
  . . . The District of Columbia is a diamond-shaped square, ten miles on a side. In 1791-92 Andrew Ellicott, with Benjamin Banneker and colleagues, slashed through the wilderness, surveyed the bounds of the Federal City, and placed marker stones every mile along the edge. Many of these forty historic stones yet survive. My self-imposed quixotic mission: visit them, photograph them, and record their GPS coordinates. This page contains a Google Map of the results. (The associated XML contains the latitude and longitude information which generates that map.) See http://flickr.com/photos/zhurnaly for photos and commentary.
