 The AMC maintains the AT from the New Hampshire border to Grafton Notch, with the Maine Appalachian Trail Club responsible for maintaining the remaining miles to Katahdin.Beginning in the late 1980s, the NPS and ATC challenged the Saddleback Mountain resort in Maine over development of private land that the AT traversed.The dispute continued a decade later, and after a June 1996 meeting between the two sides, NPS and ATC relented from some of their previous positions and reduced their proposed land-acquisition corridor by 70 percent.
