It was the middle of May 2018 when I first landed on Isle Royale. That storied island—that mass of rock isolated in northern Lake Superior. So far away it seems logically like it should be part of Canada, yet it belonged to Michigan—the only National Park in my home state. The mystery of that island beckoned me from maps with its geography and isolation. Long had I wanted to discover what this coveted gem had in store.
At long last, I finally visited the island after spending a winter and a spring teaching environmental education in northern Minnesota. By that time, I had become quite familiar with the boreal northwoods from all those hours teaching kids in the wilds. The northern forests, hence, were not all that different from my everyday existence.
Given my years of anticipation, Isle Royale was bound to be something exceptionally different than what one could experience on the mainland, I believed.
As it was, my first trip to the island was a simple, short overnight stay, ferrying in from Grand Portage, Minnesota to the Windigo Visitors Center on the western end of the island. As far as landscapes go, the flat, forested, mixed-conifer forests of Windigo are not spectacularly different than the Minnesota Northwoods I had become accustomed to.
I was a bit underwhelmed.
I didn’t even bother to take any pictures (incidentally, my camera had broken earlier that trip).
I left Isle Royale that trip convinced that I had seen the island in the wrong way. A simple overnight trip was no way to do the island ecosystem justice. If I was ever to return to Isle Royale, I thought, I would do it in the right way: I would hike the island from end to end, slow enough to absorb the ecological transitions, to understand the essence of what makes the place, and to enjoy immersion in the vast isolation of Isle Royale.
As chance would have it, in the summer of 2019 I was selected to take part in a volunteer restoration crew on Isle Royale’s Rock of Ages Lighthouse. I would be returning to Isle Royale sooner than I had thought, and this time, I would be staying on to hike across the island afterwards.
I started my hike on the western end of the Island, at Windigo, the widest part of the island. Here the forest commands the land and the coastline is smoother, less jagged. I made my way to the Greenstone Ridge trail, the hiking path that transects the middle of the island. Despite its name, the Greenstone Ridge at this point isn’t much of a ridge at all. The trail slowly climbs uphill under the cover of a mixed-forest—conifers, but also maples and even the warm-and-dry loving oaks. I spent my first night at the interior campsite of Island Mine, the site of an 1870’s copper mine that peaked and was abandoned in only a few years.
Mining history would be a big theme of the hike, and copper was the resource of value. It wasn’t just white Euro-Americans who were mining the island either: the Ojibwe, the indigenous people of Isle Royale, had mined the island for thousands of years. Archeological evidence suggests that as early as 4500 years ago, indigenous people harvested copper by using stones to hammer off chunks of native copper from outcroppings in the bedrock. As their technology progressed, they began to mine deeper in the bedrock by building large fires over ore deposits, then quickly dousing the fire with water in order to crack the bedrock. Small indigenous mining pits can still be seen throughout Isle Royale today. By the 1840’s the Objibwe had been duped into ceding their lands to settlement and development for the resource-hungry Americans. Speculators flocked to the island to make their riches, but mining on Isle Royale was always boom or bust. Island Mine organized in 1874 and extracted over 200,000 pounds of refined copper. Three years later, the company went bust. All that remains now are scattered pieces of rusting equipment and mounds of tailings.
Day two saw me continue east along the Greenstone Ridge. After a few miles of hiking through the shady canopy, I began to get my first views from the ridge: small, rocky clearings at first with scrubby oaks and small shrubs partly obscuring the views. First the clearings were few and far between, but then they became more abundant. From the ridge one could begin to see some of the inland lakes that dot the island, including the scenic Lake Desor, near the summit of Mount Desor, which at 1,394 feet is the highest point on the island. From clearings further along I could even see Ryan Island in Siskiwit Lake, the largest island in the largest lake on the largest island in the largest lake.
With the gradual opening from shady forest to open ridge, another fun thing happened: berries. Up on the ridge, the sun beats down and the soil becomes dry. The seasons progress quicker than by the lakeshore where Lake Superior tempers the weather. Whereas the thimbleberries at lower elevations were still hard and green, up on the ridge I began to encounter a progression of ripeness: first, an isolated red berry, then a few on a bramble, and finally whole thickets of the bright red berries. Thimbleberries are a thornless, velvety cousin of the raspberry, with shallow bright red berries which are so soft and juicy that they can only survive the journey from the hand to the mouth.
After gorging myself on snacks of thimbleberries and taking a mid-afternoon swim in the cool and clear Lake Desor, I made my campsite at Hatchet Lake.
The clear summer weather finally took a turn for the wet on my second night. It was a constant heavy rain that slowly drenched me. I awoke (did I even sleep?) with about an inch of standing water in my tent. I later learned that at Windigo they recorded nearly two inches of rain in that overnight.
I would start my third day soggy. Today I would be leaving the Greenstone Ridge trail for the north shore of Isle Royale and the infamous Minong Ridge. I reached Lake Superior at Todd Harbor, a picturesque cove with a mélange of water-smoothed rocks. I took a short side hike to the former open pit of the Haystack Mine, and then followed a trail just a little bit further to find a small waterfall that was the cause of some bubbling noise off in the distance. From Todd Harbor I took the Minong Trail towards McCargoe Cove. The Minong Trail, though it never reaches as high elevations as the Greenstone Ridge, deserves its reputation as a knee-destroyer. The Minong Ridge is a series of exposed escarpement ridges: a rocky, uneven gradual climb up the bare basalt, followed by a steep dropoff on the backside. Then repeat, again and again. On a hot day, it wears you out, as it wears out your knees.
I reached the deep and slender McCargoe Cove by mid-afternoon, and after such a soggy night, I was eager to rest and dry out. This afternoon, I finally got a shelter at one of the island’s campsites. They are spacious lean-tos, screened-in, and with the perfect combination of both scenic views and isolation. I dried my clothes off and basked in the sun.
Though McCargoe Cove was my favorite campsite of the hike, there were not many people there at all. Isle Royale consistently is the least visited national park in the contiguous 48 states. In 2017, this National Park had only more visitors than Lake Clark, Kobuk Valley, and Gates of the Arctic National Parks, all sites in remote interior Alaska. With only 28,196 people even paying a visit in all of 2017, more people visit parks like Yellowstone in a single day than all of Isle Royale in an entire year. The great benefit of Isle Royale’s lack of popularity is its solitude. The trails and campgrounds never feel crowded. With fewer folks around, you also develop good connections with your fellow travelers quite readily. At McCargoe Cove, I spent the evening around the campfire chatting with our only neighbors: a group of fishermen from Chicago and a pair of ladies from the Twin Cities. Trail community seems to come easily here.
McCargoe Cove was also the harbor used for the Minong Mine, the most prolific mine in Isle Royale’s history. Like other island mine sites, indigenous people had harvested surface copper deposits here first. In 1872, modern mining operations had commenced at Minong. This mine produced some incredible finds, such as a 5,720 pound nugget of almost pure copper. Finds like this nugget, and several other massive nuggets, added fuel to the mining fire. Two shafts were dug, up to 300 feet deep, as well as several drift tunnels that followed the ore veins. As tunnels were dug, tailings, or waste rock, began to fill in the adjoining marsh that leads to McCargoe Cove. A boomtown known as Cove sprang up at Minong, housing upwards of 150 people at its peak. Along with its railroad, stamp mill, and blacksmith shop, Cove even boasted a post office. Indeed, the prospect of permanent settlement on Isle Royale seemed so promising that Isle Royale even became its own county in 1875. By 1885, however, all mining operations on Isle Royale came to a halt for good. The grade of the ore dwindled and the price of copper fell; Isle Royale proved to be too isolated and the winters too harsh. Eventually, even though over 4 million pounds of refined copper were removed from the island, all mining ventures proved too non-economical to continue. Island boomtowns were abandoned. By 1897, with no permanent population left, Isle Royale County was re-absorbed into Keweenaw County.
On my fourth day, after very much enjoying my single-night stay in the shelter, I was off to hiking again. This time I decided to traverse the island from north shore to south shore, hiking astride several interior lakes along the way. I had been told that these interior lakes were hotbeds for moose activity. As storied and prolific as the moose population on Isle Royale has been, I had yet to see my first moose on the island. I knew they’d be around, as I had already seen plenty of moose scat and browse sign.
The scenic and shapely-named Chickenbone Lake proved of no avail for moose, though it was a Mecca for giant dragonflies. The next lake over, at Lake Ritchie, I got my first far-off glimpse of a moose browsing in the aquatic vegetation far across the lake. With the gradual decline of the predatory wolf population, the numbers of moose on Isle Royale have skyrocketed in recent years, with an estimated 2,000 moose inhabiting just over 200 square miles of island (learn more about Isle Royale Wolf-Moose dynamics here). I would only end up seeing one other moose on my trip. After losing the hiking trail on some bedrock, I wound up following a moose trail into the woods. The moose trail petered away until I reached a swamp. Suddenly, a large startled moose crashed away from me through the brush!
Though I had seen two moose, as far as their illustrious predator the wolves went, I had yet to see any. When I had visited previously in 2018, there was just a pair of wolves left on the island, simultaneously a brother-sister pair and a father-daughter pair (you do the math on that inbreeding!). In the winter of 2018-2019, four more wolves were introduced to reinvigorate the existing wolf population. For anyone, seeing a wolf is a rare treat. Alas, I never had a wolf encounter on the island; the closest I got to seeing the wolves was the island cabin of well-known wolf-moose researcher Rolf Peterson.
Once at the south side of the island, I camped at the large harbor of Moskey Basin. Completely different from the small, sparsely-filled campgrounds I had been staying at, Moskey Basin was filled to capacity with both families and large groups, and its vast expanses of exposed bedrock and its picnic tables made this site feel luxurious and tame. But I should have expected that, visiting in high season after all. Even in high season, though, Isle Royale is not that busy, and getting all of that wilderness ambiance while hiking was a treat not to be taken for granted.
The cove at Moskey Basin was a sight to behold—layers of exposed bedrock outcroppings running right into the water. I hadn’t noticed it too much before, but the island was becoming rockier and rockier the further I traveled east. The exposed rocks left plenty of good places for sunbathing and also proved to be a prime habitat for blueberries (thimbleberries, unfortunately, had all but disappeared after leaving the Greenstone Ridge). Also without my noticing, the broadleaf tree canopy had disappeared too. Thin soils could no longer support the large broadleaf trees seen more westerly on the island. Instead, the forest was becoming more a stunted array of firs and spruces.
With a clear night ahead looking promising, I made a commitment to staying up to see the stars. This being mid-summer in the westernmost Eastern Time Zone, the sun did not set until near 10pm, and the stars did not emerge until well afterwards. After a full day of hiking, I was usually in my tent well before the stars came out in their full glory. But I stayed up tonight and was treated to a show on an absolutely moonless night. Being miles away from any human settlements, the stars on Isle Royale are absolutely amazing!
My last day on Isle Royale would take me into the primary tourist outpost at Rock Harbor. Rather than hugging the shoreline trail to my final destination, I once again went inland to take the Greenstone Ridge home. The trail up to the Mount Ojibway Fire Tower was never too steep, provided uninterrupted views, and proved to be premiere blueberry habitat. The whole climb up I had a constant handful of blueberries as a power snack. The Mount Ojibway Fire Tower, unlike its much squatter kin at Mount Ishpeming, actually provides visitor access to the base. Climbing the tower provides views of the entire island from north to south.
The Greenstone Ridge continued its path northeast across exposed rocky and grassy balds. By the time I reached the Mount Franklin lookout, it was clear I was encountering a different area. The overlook was populated with day-tourists hiking up from their various Rock Harbor lodgings. I left the viewpoint and went on the downhill to Rock Harbor and my hike’s end. At the eastern end of the island, Isle Royale’s tilted geology splits the island into many narrow peninsulas and long bays running towards the northeast. I walked along these deep harbors right along the trails by the edge of Superior’s turquoise waters.
A sign for campsites signaled that I had made it into Rock Harbor. I could now bask in the luxuries of this tourist depot. Modern settlement at Rock Harbor started with a few unsuccessful mining ventures in the 1840’s, then moved into the realm of commercial fishing, as Scandinavian immigrants built their fishing shanties after the copper booms. By the early 1900’s, these fishermen were guiding pleasure-seekers around the island and accommodating throngs of tourists in cabins. Several resorts eventually popped up, having their heyday in the 1920’s. The Great Depression and changing societal tastes caused a drastic decline to tourism in the 1930’s. By 1940, Isle Royale had been declared a National Park, and the National Park Service began the process of buying out and shutting down the remaining tourist resorts and removing fishermen from the island. Gradually, this formerly logged, mined, and settled island would be transformed into a 99% wilderness park with no permanent population.
Today Rock Harbor boasts a store where one can buy fresh vegetables as well as craft beer, hot showers ($6 for a five-minute shower), laundry, a restaurant, rustic cabins, and even a few hotel rooms. For this wilderness traveler, it was a world apart from the Isle Royale I had just experienced. The development at Rock Harbor was a foil to the isolation of the island. Though I milled about the Rock Harbor Village for a while, it just wasn’t what I needed. I made off to a quiet edge of Lake Superior and took a long, cleansing swim in her waters. For me, that is what Isle Royale is about.
