About the Louisiana Purchase State Park

Everything has to start somewhere and the surveys for the Louisiana Purchase started right here in Arkansas.

The Louisiana Purchase more than doubled the size of the United States. The area that is now Arkansas was part of that purchase.

At this state park, you will find a 950-foot elevated boardwalk over the swamp that will lead you out to a granite monument that marks the “initial point” where the surveys started.

On November 10, 1815, a party led by Prospect K. Robbins surveying a north-south line to be known as the fifth principal meridian crossed an east-west baseline that had been surveyed by a party led by Joseph C. Brown. The crossing of those lines became the “initial point” from which subsequent surveys of Louisiana Purchase lands originated.
