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.

This 27-acre property was made famous by Teddy Roosevelt, who visited the area beginning in 1878. As a young man under the guidance of his lifelong friend and guide Bill Sewall, Roosevelt camped at the southern end of Mattawamkeag Lake and hunted and fished throughout the area. It was reported that, each day, Roosevelt would take his bible and hike to a beautiful point of land at the confluence of the West Branch of the Mattawamkeag River and First Brook where he would read the bible. A plaque at the site commemorates Roosevelt's love for the area.
