. 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. Totals of well over 250 inches annually are likely in the higher elevations. 300-inch seasons are not uncommon in this region.

Porcupine Mountains State Park was established in 1945 to protect this large stand of old-growth forest, much of "maple-hemlock"type. In 1972, Michigan passed the Wilderness and Natural Areas Act.

The facilities provided by the park include an extensive network of backcountry trails for hiking and wilderness backpacking, rustic trailside cabins, modern campgrounds, swimming and boating areas, and various interpretive programs led by park ranger
