The northern Michigan landscape of Ontonagon County is defined by its deep roots in the Copper Country mining era, as shown in this 1982 provisional survey. The village of Greenland and the nearby settlement of Mass serve as the primary hubs of human activity, situated at the base of Adventure Mountain. This area was a critical node in the region's mineral extraction history, evidenced by the presence of Lake Mine and the rail-oriented geography of Greenland Junction.
