After a rocky first week of geology field work in Chibougamau, pun intended, our fortunes were about to improve. You could say we’d hit rock bottom… Okay, I’m pushing it now with the dad jokes. Just to recap some of our mishaps: we lost one of our GPS devices somewhere in the forest, we lost one of the truck’s side mirrors, and we got it stuck in deep mud, requiring the other team to come pull it out. At least we were being productive and getting some rock samples. Well, at least Alexandre was. I couldn’t reach one of my primary targets due to the thick forest and overgrown roads.
But field work has a funny way of balancing things out. Just when it feels like the forest is determined to humble you, something finally goes right.
Heavy Duty Sampling
As we got more accustomed to the terrain and our new sampling routine, we were becoming increasingly efficient with our time. Regular geological field sampling usually involves finding a good representative outcrop and hammering off a few fresh pieces of rock from it.
In the Canadian Shield, however, the outcrops are most often flattened, rounded, and polished by ancient glacial activity. That makes it highly difficult to hammer any decent rock pieces out of them. Even when using a chisel, we would usually end up with thin, superficial weathered chips that would yield poor geochemical results. Hardly representative of the magmas that had crystallized billions of years ago.
In Canada, however, we had an alternative method of sampling, something I had never seen, nor needed to use during field work in Europe: a rock saw. Or a concrete saw, as some call it. Essentially a hand-held motorized saw fitted with a large diamond cutting blade. A chainsaw for outcrops, if you will.
This thing… was impressive. It was big, heavy, loud, and an absolute pain on the lower back to use. But boy, could it sample. Instead of hammering on a flat outcrop for half an hour only to collect a few useless weathered fragments, we could cut thick slabs of fresh, unaltered rock straight from the interior of the outcrop. As an added bonus, the vibration and exhaust during cutting kept most of the bugs away. Suffice to say, it quickly became our preferred method of sampling.
The rock saw did have two major downsides. It required a nearby water source to fill the cooling pump tank, and it was quite cumbersome to carry on longer hikes deep into the dense forest. However, for the easier-to-reach outcrops, it was a no-brainer. It saved us an incredible amount of time.
The Needle in a Haystack
One day, after becoming quite efficient with our rock saw, we managed to finish the day’s sampling targets surprisingly early. With plenty of spare time on our hands, Alexandre and I decided to head back to the forest where our GPS had gone missing during the first week. Maybe, just maybe, we could find it somewhere near the road.
We only had an approximate idea of the location since there were no GPS tracks to follow back. Alexandre parked the truck in roughly the same area where we thought we had stopped before. We headed into the forest and began searching. Pretty quickly, though, it became clear that this was a hopeless task.
The forest all looked the same. Thick bushes and tangled underbrush everywhere. The ground covered in a soft carpet of leaves, moss, and rotting branches. We wandered around for five or ten minutes before Alexandre finally gave up. It was the very definition of a needle-in-a-haystack situation. Defeated, we slowly wandered back toward the truck, still half-heartedly scanning the ground as we walked.
As I neared the road and slowly put one foot in front of the other, something caught my eye.
A faint flash of bright orange beneath the leaves, right where I was about to step.
THE GPS.
Against all odds, almost as if guided there by sheer luck, my foot nearly landed right on top of it. My eyes lit up. My jaw dropped. I bent down, grabbed it, and with a triumphant battle cry echoing through the forest, raised it high above my head like a long-lost trophy. We couldn’t believe it.
It was a moment of pure disbelief, followed by sheer amazement and slightly manic laughter. It felt like a sign. Fortune had clearly turned in our favor.
“Pluton de France” the Second Attempt
After that stroke of luck, I decided to take another shot at Pluton de France on my project’s next field day. Since we had failed to reach the outlined polygon on my map by car the previous time, I wanted to attempt it on foot instead. This was going to be a bold undertaking, as the bush in this particular part of the Abitibi looked extremely dense.
Alexandre wasn’t too keen on the idea of a long, arduous hike through the boreal jungle. Fortunately, Adrian happened to be free that day and was willing to join me. So for one day I swapped partners and headed back northeast toward the elusive intrusive rocks somewhere near the edge of the Abitibi Greenstone Belt.
We drove as far as we could, essentially until we reached one of the old roads that had once led toward my target area. The road, however, had long since been reclaimed by nature. It was completely overgrown by dense alder thickets.
These alders seemed to thrive anywhere the forest had once been disturbed. Where logging had opened the canopy, they quickly took over the landscape. They grew like a strange hybrid between bushes and small trees—clusters of multiple thin trunks sprouting from a single base in the ground. Their branches were flexible, tightly packed, and tangled together into nearly impenetrable walls of vegetation.
Ironically, pushing through these alder thickets was often far more difficult than walking through the untouched forest. At least beneath the mature spruce and pine trees there was space to move. In the alder patches, however, every step became a battle against springy branches and dense foliage that refused to let you pass.
Swimming in Trees
We powered through as best we could, large tool-filled backpacks and all. This was easily the worst forest trekking of the entire field trip. We were legitimately fighting the forest inch by inch. Roots constantly tripped us up, while dense branches grabbed at our clothes and gear. This was the moment when I coined the phrase “swimming in trees.” The large sledgehammer sticking out of my backpack kept snagging on branches every few steps, which certainly didn’t help.
Still… we pushed on. Slowly. Extremely slowly. Fighting for every meter through an endless wall of dense bush. After a couple of hours of this, we finally reached the Pluton de France polygon according to the geological map.
And of course, there wasn’t an outcrop in sight. However, further ahead we noticed what looked like a small rise in the terrain. A hill meant there was a chance that bedrock might be exposed beneath the soil. So we pushed on. Eventually we reached a small incline and decided to start digging. We removed thick layers of leaves, branches, and soil until we struck rock. Finally!
The problem was that it looked… strange. Dark, heavily weathered, and altered by the soil to the point that I couldn’t immediately identify it. So we kept digging, clearing away more of the surface. When we finally managed to hammer off a few pieces, the truth became obvious.
It wasn’t what I was looking for at all. Not even close to what the map had suggested.
Pluton de Lies
Blasted inaccurate map, I thought. Still, we were close to the edge of the polygon, so I took a sample anyway and suggested we push a little farther toward the nearby lake that covered much of the mapped area.
Somewhere around that time another thought crossed my mind: this would be an absolutely terrible place to have a wildlife encounter. If we ran into a bear here, there would be no easy way to escape the sea of trees surrounding us. Then again, perhaps a bear would be smart enough to avoid pushing through such thick forest. Unlike us.
Some time later, deeper inside the target area, we finally found a small clearing near the top of the hill. To my relief there were even a couple of outcrops exposed there. Of course, they were perfectly flat and glacially polished—impossible to sample properly without the rock saw.
And worse still… It was once again the wrong rock type. Dark, heavily altered basalt everywhere instead of the light-colored granitoids I had been hoping to find. What a disappointment.
More than anything, I was frustrated with the map itself. These geological maps, after all, are produced by the Québec Ministry during annual field campaigns. But even those teams can only cover so much ground, and sometimes the boundaries of geological units end up being… educated guesses. I marked the location on the map to note the discrepancy and kept the token sample from the previous location as reference.
Lucie later appreciated the effort, but she still had me discard the sample since it wasn’t useful for the project. All that effort. All that struggle through the forest. For nothing. But that’s field work. You win some. You lose some.
Roaming the Chibougamau Region
We continued our sampling campaign well into August. Alexandre’s project took us all around the Chibougamau area—from the high cliffs northeast of the lake to the far western stretches near Oujé-Bougoumou.
On the western side of the Chibougamau pluton, we stumbled across several piles of trash near Oujé-Bougoumou. A sad and unfortunate eyesore in an otherwise vast and pristine wilderness. We also came across numerous animal tracks, mostly large canine ones. Likely local dogs, though wolves were certainly not out of the question.
The only wildlife we consistently encountered, however, were the grouse, or as I liked to call them, forest chickens. We had heard plenty of stories about them beforehand, usually involving their questionable survival instincts. Instead of fleeing from danger, these birds, especially protective mothers, would often charge directly at the perceived threat in a rather unconvincing display of bravery. Not the best strategy when facing modern human inventions like trucks.
On foot, however, they were simply amusing. They would follow us around at a cautious distance, clucking and posturing, as if politely insisting that we leave their territory.
In the northeast, on the other hand, we encountered more “exciting” forest roads for our battle-hardened truck. At one point, a deep natural ditch carved out by a small creek abruptly killed the engine as the truck dropped into it—perfectly synchronized with the beat drop of the music playing in the car. No lasting damage, but plenty of dramatic effect.
The southern Wetlands
Whenever we shifted focus back to my project, we found ourselves driving farther and farther away from Chibougamau.
One day took us deep south toward a small intrusion known as the Hazeur pluton. The landscape there transitioned from dense forest to open wetlands. At one point, the water had quite literally claimed part of the road. Alexandre, understandably, was having flashbacks to our previous encounter with waterlogged terrain that had left us completely stuck. This time, however, there was no mud, just firm gravel beneath the shallow water. We proceeded cautiously and made it through without issue.
At the end of the road, a small outcrop, or possibly just a very large boulder, awaited us. The quiet swamp surrounded us on all sides. Far removed from any main road, it felt like prime territory for wildlife encounters. We spotted a few birds, including a large and majestic sandhill crane. In the distance, the eerie calls of loons echoed across the wetlands, occasionally interrupted by the faint howling of wolves.
A true call of the wild.
Despite that, there was no real sense of danger. We were working right next to the truck, heavy tools within reach. If anything, I felt completely at peace. There were barely any bugs, the scenery was wide open and beautiful, and for a moment it felt like we had stepped into a nature documentary.
To top it all off, I managed to collect several excellent sample blocks for my study. Easily one of the best locations we visited during the trip.
Blood for Samples
Another day took us west, past Chapais, toward a small syenite intrusion known as the Dolodau Stock. There, I finally managed to collect some of the best samples for my project. But the bounty came at a cost. Blood. We had wandered deep into black fly territory, and they were out in the millions. We were the main course.
Between hammering rocks and repeatedly drenching ourselves in bug spray, we uncovered one of the most fascinating outcrops of the entire campaign: a carbonatite unit, quite a rare igneous rock type, crosscut by sulfur-rich syenite veins.
Shiny disseminated pyrite cubes sparkled within the syenite. Grey magnetite blobs and black flaky micas stood out against the white carbonatite. Thick, blocky calcite veins cut across the outcrop like frozen rivers of stone. It was a geological treasure trove.
Throughout our field days, we often stumbled upon vast patches of wild blueberry bushes. Whenever we finished early, we would start gathering and snacking. Before long, we had collected an impressive haul, which we eventually brought back to base to dry and preserve.
The Final Days
The August days slipped by quickly, and our field campaign began drawing to a close. A few moments from that final week still stand out.
One of them involved walking along a set of railway tracks to reach a cliffside outcrop. It was a surprisingly calm day. No bushwhacking, no brutal driving, just a relaxed walk and straightforward sampling.
On another day, possibly our last, we aimed to reach one final target within the Chibougamau pluton. It was an easily accessible outcrop near a side road running parallel to the main road. However, the only connecting route required a long detour. Naturally, we decided to make things more interesting.
After finishing our work, and soaking our boots while crossing flooded ground, I suggested taking a shortcut based on the map. Alexandre hesitated, but eventually gave in. I think we were both feeling a bit nostalgic about pushing our luck one last time. A sharp turn later, we found ourselves driving through a wet, sandy stretch just before a ramp leading up to the main road.
And… the truck got stuck. Again. This time, however, we were ready.
I jumped out to assess the situation while Alexandre quickly wedged traction aids under the tires. On my signal, he floored it, and the truck launched itself free, gliding across the remaining sand with ease. We had clearly graduated from the school of getting stuck in the mud.
A Thunderous Roar Downstairs
Back at base, we needed to dry our soaked boots for the next day. There was a designated drying room, but it wasn’t quite enough for boots that wet. So naturally, we came up with a brilliant idea:
We put them in the dryer. The sound was… apocalyptic.
The machine roared and thundered as it violently tossed the heavy boots around inside, like drums announcing the end of the world. We closed every door we could, but the noise still echoed through the building like a distant storm. Miraculously, the dryer survived. And so did our boots.
The End of a Successful Field Campaign
On one of the final evenings, the sky was perfectly clear. No moon, no clouds. I suggested we drive out of town and stop at one of the abandoned quarries for some stargazing. After some hesitation, Nesrine and Adrian agreed. It was well worth it.
Above us stretched a breathtaking night sky. The Milky Way cut across the darkness, its bright star clusters contrasted by the deep shadow of the dark rift. As we stood there in silence, we once again heard wolves howling in the distance. It felt like the perfect ending to our time in the wilderness.
After 28 days of field work, we had collected 24 buckets of rock samples. Despite the rough start, we had successfully completed our summer campaign during one of the strangest years in recent history, 2020. A year when the world seemed to shut down. When uncertainty, isolation, and restrictions became part of everyday life.
And yet, out there in the wilds of northern Canada, things felt… different. For a while, we were free.
Free to work.
Free to explore.
Free to live something that felt almost normal again.
It wasn’t always easy. There were frustrations, setbacks, and long exhausting days. But there was also laughter, discovery, and moments that stayed with us. Moments that Alexandre and I still find ourselves retelling years later. And just like that, it was time to head back to Chicoutimi.
Back to our strangely constrained lives as PhD students in a world that hadn’t quite opened up again.
