Porcupine Mountains, Nature reserve in Upper Peninsula, Michigan, United States
The Porcupine Mountains contain 60,000 acres of wilderness terrain, featuring old-growth forests, waterfalls, Lake Superior shoreline, rivers, and mountain ridges.
Michigan Department of Natural Resources established the Porcupine Mountains State Park in 1945 to protect North America's largest old-growth northern hardwood forest west of Adirondacks.
Native Ojibwa people named these mountains based on their silhouette formation, which resembles the outline of a crouching porcupine against the horizon.
Visitors access over 90 miles of hiking trails, modern campgrounds, rustic cabins, swimming areas, and interpretive programs guided by park rangers throughout the seasons.
The mountains receive extreme lake-effect snow from Lake Superior, with annual accumulations reaching 250 inches at higher elevations, creating winter recreation opportunities.
