I grew up in Maine. The area in green is rather rugged terrain. It's the end of the appalachian mountains with lots of sharp features cut by receding glaciers, then to top it off, it's very dense forest. Topo map (http://www.geomart.com/images/raisedrelief/me.jpg http://www.geomart.com/images/raisedrelief/me.jpg) Large portions of that area are also owned by paper companies. They obviously use it for harvesting trees but also open it up for public use. That makes it sort of a quasi national park type area except that it's privately owned. There are also a lot of privately owned 'outdoors' cabins up there where hunters/campers go in the summer, and snowmobilers in the winter. Not many people 'live' there, but during some periods of the year there are a fair number of people around, particularly near the larger lakes. It is a beautiful and relaxing area, I head up there once a year to go camping and 'unplug' from Boston for a week. It is somewhat refreshing to be 80 miles from the nearest paved road and 5 miles of canoe paddling from your vehicle.
