The stone marker at the Initial Point of the Louisiana Purchase survey. It was placed in 1926 by the Daughters of the American Revolution.br/ Taken at the Louisiana Purchase State Park, in eastern Arkansas. In 1815, President James Madison ordered that the lands of the Louisiana Purchase be properly surveyed. So two surveyors headed out that year to begin the task of surveying the wilderness. They decided to begin in Arkansas, but probably regretted that decision when they began to slog through the swampy terrain of the Delta.br/ One of the surveyors headed out from the confluence of the Arkansas and Mississippi Rivers, the other one from the confluence of the Arkansas and the St. Francis Rivers. Where those two lines met became the initial point, and it was from this point that all surveys of the lands of the Louisiana Purchase would originate. The spot where they met was in the middle of a headwater swamp, a spot which has somehow managed to never have been drained or developed in the hundreds of years since. The swamp is now a State Park, and there is a boardwalk that conveniently takes you out over the murky waters.br/ br/ 9498-022017
