Copper Falls State Park | Green Bay

Copper Falls State Park, located just northeast of Mellen, Wisconsin, in Ashland County, is one of the most scenic and geologically fascinating state parks in the Upper Midwest. Covering over 3,000 acres, it is known for its waterfalls, lava-formed gorges, deep forests, and well-preserved CCC-era architecture. The park offers a mix of recreational opportunities with high natural and historical value.

🌊 Natural Features

Copper Falls

The park’s namesake is a 29-foot waterfall where the Bad River cascades into a deep, narrow gorge.

The falls appear coppery-red in color due to iron-rich volcanic rock and minerals in the surrounding geology.

Brownstone Falls

Just downstream from Copper Falls, this 30-foot waterfall occurs where the Tyler Forks River plunges into the same gorge to meet the Bad River.

Spectacular views are available from overlook platforms and footbridges.

Red Granite Falls

Located on a quieter trail at the southern end of the park.

Lower and wider falls where the Bad River rushes over smooth granite rock beds.

Accessible via a 2.5-mile round-trip hike.

Geological Background

The landscape was shaped by Precambrian lava flows, glacial erosion, and the cutting action of the Bad River system.

Deep gorges, lava rock ledges, and red and black stone formations dominate the terrain.

Erosion has exposed volcanic layers estimated to be over 1 billion years old.

🌲 Forests and Ecosystems

Dense northern hardwoods and coniferous forest cover most of the park.

Key tree species include sugar maple, yellow birch, hemlock, white pine, and spruce.

Wetlands along the riverbanks support a rich variety of mosses, ferns, and wildflowers.

In fall, the forest explodes with vibrant red, orange, and gold foliage, making the park a popular leaf-peeping destination.

🐻 Wildlife

Common sightings include white-tailed deer, raccoons, red foxes, and porcupines.

Occasionally, visitors may spot black bears or even hear howls from gray wolves.

Birdwatchers can expect to find pileated woodpeckers, great horned owls, eagles, ravens, warblers, and loons near Loon Lake.

Amphibians such as frogs, salamanders, and wood turtles are frequently seen along damp trails.
