 The initial point was located as the place where these surveyed lines intersected (this is one of many examples where the meridian line and base line determined the initial point, rather than the other way around).As a result the initial point is in the middle of a high water swamp, on land that belonged to the Davidsons of Marvell, Arkansas.The family made this portion of their farm available to the state, and today the site, Louisiana Purchase State Park, consists of a boardwalk leading from a parking lot into the swamp.
