The public now has the opportunity to weigh in on a proposed land exchange that’s been brewing for four years on the east side of the Crazy Mountains. …The Custer Gallatin National Forest released a Preliminary Environmental Assessment for the East Crazy Inspiration Divide Land Exchange Project on Wednesday, signaling a possible resolution to what has been a long-simmering dispute over public access to the region. The agreement would exchange 4,135 acres of forest lands for 6,430 acres of private lands, owned by six private property owners in the Crazy Mountains and near the Inspiration Divide Trail in Big Sky. …The 45-day public comment period on the proposal runs through Dec. 23. “The Crazy Mountain’s checkerboard ownership pattern of private and public lands has contributed to over a century of complicated management situations and problematic access issues for all users,” the Forest Service said.
