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.

Meteorology

The mountains are subject to heavy

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 . Totals of well over annually are likely in the higher elevations. It is not uncommon to have seasons in this region.

State park

Porcupine Mountains State Park was established in 1945 to protect the area's large stand of old-growth forest, much of it of the "maple-hemlock" type. In 1972, Michigan passed the Wilderness and Natural Areas Act. This act gave the park the new designation of the Porcupine Mountains Wilderness State Park. 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
