North Maine Woods Headquarters, Maine

This small white Main Street house is the administrative headquarters for the North Maine Woods, one of the largest private tracts of land in the country. Extending north from Moosehead Lake and Baxter State Park to the Canadian border, the 3.5 million acre tract has no towns or paved roads. Access to the North Woods is controlled, with manned and unmanned gates at its dozen or so entry points. The roads within it are considered private, built by and for logging companies, and a fee is charged for access. The land is mostly owned by a few companies, including the Irving Company, the New Brunswick-based oil and paper company, and the Seven Islands Land Company, which manages a million acres owned by the Pingree family. Though it is heavily logged, in other ways it is one of the least developed regions of the continental United States.
