This National Historic Landmark, located at the junction of Lee, Monroe and Phillips counties, preserves the initial point from which all surveys of the property acquired through the Louisiana Purchase of 1803 initiated. That year, President Thomas Jefferson purchased the vast territory of Louisiana from France for $15 million. The unmapped wilderness of approximately 900,000 square miles doubled the size of the fledgling nation and helped shape the destiny of the United States.
The barrier-free boardwalk features wayside interpretive exhibits that tell about the Louisiana Purchase, and describe the flora and fauna of the surrounding swamp. The headwater swamp is representative of the swamplands that were common in eastern Arkansas before the vast bottomlands were drained and cleared for farming and commercial purposes.
