The Porcupine Mountains, or Porkies, are a group of small mountains spanning the northwestern Upper Peninsula of Michigan in Ontonagon and Gogebic counties, near the shore of Lake Superior. The area is part of the Porcupine Mountains Wilderness State Park. The Porcupine Mountains were named by the native Ojibwa people, supposedly because their silhouette had the shape of a porcupine.
The Porcupine Mountains were the site of copper mining in the 19th century. One of these mines is the Nonesuch Mine, which operated sporadically from 1867 to 1912. The Porkies are also the location of a large stand of old growth forest, and home to many black bears. The area is popular among tourists, especially the Lake of the Clouds in the heart of the mountains. There have been numerous bear sightings.
The most striking geological feature of the Porcupine Mountains is the long basalt and conglomerate escarpment parallel to the Lake Superior shore and overlooking Lake of the Clouds, a continuation of the same copper-bearing bedrock found farther northeast on the Keweenaw Peninsula. A second ridge farther inland, on the other side of Lake of the Clouds, includes Summit Peak, the highest point in the mountains at 1,958 feet (595 m). Rivers, waterfalls, swamps, and lakes lie between the rocky outcroppings. There are a number of waterfalls on the Presque Isle River in the extreme western side of the park.
The mountains are subject to heavy lake-effect snow from Lake Superior. The relatively high elevation of the mountains and their proximity to the lake provide perfect conditions for lake-effect snow, but no official records are maintained anywhere in the mountains. The closest National Weather Service station is in the coastal community of Ontonagon, where the annual average is about 200 inches (510 cm). Totals of well over 250 inches (640 cm) annually are likely in the higher elevations. It is not uncommon to have 300-inch (760 cm) seasons in this region.
