Drive as far north as you can in Michigan’s Upper Peninsula, to the town of Copper Harbor, and almost to the northern terminus of US Highway 41, and you will be just a mile or so away from a rare tract of old growth timber called the Estivant Pines. This bit of land was once owned by Edward A.J. Estivant, of Paris, France. He had purchased 2,400 acres of land just south of Copper Harbor in 1861. By 1900, only 1,700 acres of virgin forest remained.
The land was purchased from Estivant by the Calumet and Hecla Mining Company in 1947, who used it as a timber resource. They, in turn, sold it to Universal Oil Company in 1968 who logged about 300 acres. At that point, local citizens and the Michigan Nature Association began taking steps to save the remaining virgin forest. They raised enough money to purchase about 200 acres from Universal Oil Co. and created the Estivant Pines Nature Sanctuary. Subsequent acquisitions brought the total protected acreage to 570.
We decided to hike the Estivant trails this morning. There had been rain last night, the temp was around 70, and the humidity was relatively high, giving us the sense that we were walking through rainforest. There were towering white pine trees, some as old as 500 years and up to 4 feet in diameter, as well as sugar maple, red oak, river birch, yellow birch, balsam, cedar and more. I read that there are over a dozen species of orchid in the sanctuary but I didn’t see any (or didn’t recognize any since we are past blooming season.)






We hiked both of the trail loops, the 1.2 mile long Memorial Grove Loop and the 1 mile Cathedral Grove Loop. It was remarkably peaceful – away from the late summer activities of nearby Copper Harbor. We did run into a few other people walking the trails, but it was far from crowded.
The trails gave us a good workout, as we navigated rocks, tree roots, mud and sand. Wear good hiking shoes. I also recommend long sleeves and long pants because of the mosquitos and “no-see-ums.” Use a good repellent for any uncovered skin – “No-Bite-Me” works well and it’s safe for children.



After leaving the sanctuary, we visited the abandoned Clark Mine, just a little ways east of there. The Clark Mining Company was organized in 1853 and operated the mine for a short time before selling it to the French Copper Mining Company. No mining was done after 1901. At
The Clark Mining Company was organized in 1853 and worked a small vein of copper. Work was suspended in 1854 and in 1855, the “Societe Francoise des Mines des Cuivres Natif du Lac Superior” purchased the property. In 1857, the property was again sold to the French Copper Mining Co. and was combined with the Bell Mining Co. Work was sporadic or done under tribute until 1901, when all work ceased. In 1942, the property was deeded to the Calumet & Hecla Consolidated Mining Co. The smokestack still stands tall and there are some remnants of old walls on site, as well as tailing dumps. It’s possible to find bits of copper if you look hard enough.
Today, it resembles a party site, with remnants of campfires, and some shattered clay pigeons on the tailing dumps.
