This section of the A.T. is crossed by several logging roads and is maintained by the Maine Appalachian Trail Club.  It consists of a small corridor of protected wilderness surrounded by large tracts of public and private land controlled by paper companies.  An increasing amount of the adjoining lands are being protected by groups like the Appalachian Mountain Club and the Nature Conservancy.
