Paradise Found, Paradise Crowded: The Thorofare's Unlikely Overcrowding Problem
There is a place in the American West so thoroughly removed from the modern world that reaching it requires roughly two days of hard travel on horseback or several grueling days on foot, where no cell signal penetrates and the nearest road sits more than 20 miles in every direction. It sounds like the stuff of frontier mythology — and for generations of hunters, anglers, and wilderness travelers, it was. That place is the Thorofare, a vast, loosely defined stretch of Wyoming backcountry straddling some of the most consequential wild land in North America. And increasingly, it is running out of solitude.
The Thorofare, at roughly 22 miles from the nearest airstrip or road, represents as remote a location as any person can reach within the United States outside of Alaska. The loosely defined chunk of land spans portions of Yellowstone National Park, the Teton Wilderness, and the Bridger-Teton and Shoshone national forests in northwest Wyoming, bordered by the Continental Divide, where Atlantic and Pacific creeks trickle from the earth before heading toward their eponymously named oceans. The Yellowstone River slices through its middle, threading through a miles-long stretch of open meadow called the Yellowstone Valley. It is, by almost any measure, one of the most spectacular and biologically dense landscapes on the continent. It is also, depending on the time of year you arrive, surprisingly busy.
The Geography of the Last Frontier
The Teton Wilderness is notable for containing the most remote location — farthest from any road — of any place in the contiguous 48 states. That distinction belongs to a point very close to Bridger Lake, near the confluence of the Thorofare and Yellowstone Rivers, not far from the U.S. Forest Service's Hawk's Rest Ranger Station. Hawks Rest, a 9,700-foot cliff band, towers over the valley — the farthest you can get from a road in the contiguous U.S.
Straddling the southern boundary of Yellowstone National Park and the Teton Wilderness, the Thorofare is further protected by Grand Teton National Park to the west and the Washakie Wilderness to the east. The sheer scale of the protected land surrounding it is difficult to overstate. The Teton Wilderness is a part of the 20 million-acre Greater Yellowstone Ecosystem. No roads penetrate it. No motors are permitted inside its wilderness boundaries. U.S. Wilderness Areas do not allow motorized or mechanized vehicles, including bicycles and all-terrain vehicles. Getting there means earning it.
The Thorofare in northwest Wyoming encompasses parts of Yellowstone National Park and a designated wilderness area in the Bridger-Teton National Forest, with several ways in, none of which take less than a long day on horseback. To reach the park ranger cabin, the typical route runs along the east shore of Yellowstone Lake, while another approach starts from a trailhead in the South Fork drainage near Cody — a ride of roughly 30 miles in a single day. For those arriving on foot rather than horseback, it takes a 30 to 40 mile hike one way to reach the Thorofare. This is not a weekend warrior destination. It never has been.
A Ranger Station at the Edge of Everything
The human history of the Thorofare runs deeper than most people realize. The Thorofare Ranger Station is one of a network of stations established by the Army in the 1880s to help guard Yellowstone's most remote borders from poachers, woodcutters, and other bad actors. Cabins may have been built there as early as the 1890s, though the current ranger station didn't start taking shape until around 1920. The cabin was rebuilt in 1937 after a kitchen fire damaged it. Grizzly bears sometimes frequent the area around the ranger station, drawn in by cooking smells. The wilderness, in other words, is not merely backdrop — it is active, alive, and occasionally dangerous.
What makes the Thorofare special — and what draws people to explore and work in the deepest recesses of the wild — is the back-to-basics isolation and the wildlife. The trip isn't for the inexperienced; it takes planning and effort just to reach the destination, and there's no cell service anywhere along the way. The Thorofare is home to all of the major species in the park, including grizzlies, black bears, moose, and wolf packs. For decades, the difficulty of access served as a natural population cap. Then something changed.
The Fish That Broke the Solitude
A Collapse Nobody Saw Coming
To understand why the Thorofare is suddenly crowded, you have to go back about three decades to one of the most catastrophic ecological disasters in the history of American freshwater fisheries. Gillnetting to suppress non-native lake trout began in 1994, the same year they were first discovered in Yellowstone Lake, with early removal efforts expanded in 2001. Nobody knows with certainty who put them there, but the leading theory involves an intentional illegal introduction — a crime against an ecosystem whose consequences would take decades to fully register.
In Yellowstone Lake, Wyoming, the largest inland population of nonhybridized Yellowstone cutthroat trout declined throughout the 2000s because of predation from invasive lake trout, drought, and whirling disease. Rivers that had appeared alive with cutthroat soon had few if any fish, with some populations declining by up to 90 percent, according to Todd Koel, Yellowstone National Park's native fish conservation program leader. The remote Thorofare region was not what it used to be in the wake of large fires that added silt to the upper river and the reduction of cutthroat that spawn in the upper reaches due to the introduction of lake trout.
For a generation of anglers who'd made the brutal trek into that backcountry, the decline was a gut punch. Had visitors come forty years ago, they wouldn't have had to look hard for fish — but they would have been sharing the river with plenty of other anglers. Twenty years ago, anglers and Yellowstone cutthroat were in equally short supply. The place had become a ghost of its legendary self, and for a while, word got around about that, too — in the worst possible way.
The Suppression Campaign
What came next was one of the most ambitious and sustained fish-removal programs ever mounted by the National Park Service. To maintain ecosystem function and conserve cutthroat trout, a lake trout gill netting suppression program was established in 1995, decreasing lake trout abundance and biomass. The work is relentless, seasonal, and extraordinarily expensive. Suppression crews deployed 89,320 gillnet units — measured in net-nights — to target invasive lake trout in a single reporting period, a logistical undertaking that rivals commercial fishing operations.
The population of mature, predatory lake trout has since been reduced by about 90 percent, giving the native cutthroat trout space to recover. In 2024 alone, teams pulled 264,650 lake trout from the waters, bringing the total haul to over 4.9 million. Models suggest there are 73 percent fewer lake trout ages six and older in Yellowstone Lake now than were present at the population's peak in 2011 — critical because older, larger lake trout have the highest reproductive potential and consume the most cutthroat. The invasive species has been in decline since 2012.
The numbers are staggering, but the scientists involved are careful not to declare victory. Lake trout suppression has influenced cutthroat recovery, and current suppression effort levels have resulted in cutthroat recovering from historical lows in the early 2000s — however, cutthroat did not achieve conservation benchmarks when incorporating the influence of disease and climate. Experts have also emphasized that lake trout cannot be completely eradicated with current techniques and will continue to require annual removal and monitoring into the future. The battle, in other words, is won on points but never truly finished.
The Return of the Giant Cutthroat
Despite those caveats, what has happened in the Thorofare's backcountry streams in recent years borders on miraculous. "Similar to Pacific salmon, the cutthroat trout of Yellowstone Lake migrate 30 plus miles into the remote Upper Yellowstone/Thorofare backcountry streams where they spawn and then return to Yellowstone Lake." Fisheries staff found large numbers and sizes of cutthroat in these backcountry streams — a dramatic shift from just ten years ago, when few cutthroat were present at all.
Yellowstone cutthroat responded by returning, literally, bigger than ever. What used to be runs of 15- to 16-inch fish are now runs of 22-, 23- or even 24-inch cutthroat. Koel can't say exactly why, but his working theory is that since most remaining lake trout are smaller, they can only effectively prey on smaller cutthroat — and so the bigger the native fish, the more likely it is to survive.
The ecological cascade has been equally dramatic. "It's amazing — the cutthroat are running up spawning streams again, and we're having bear activity like we haven't seen in quite a long time on these streams, because they're feeding on these cutthroat," says Koel, who notes that bald eagles are back and that ospreys are starting to return too. Yellowstone's fisheries supervisor Todd Koel, camping on Atlantic Creek in early July, described being stunned by "the numbers and sizes of the cutthroat that migrate that far into the wilderness from Yellowstone Lake," calling the spatial extent of the recovery remarkable.
Then the fish stories started circulating. Koel put it bluntly: "The biomass of the fish that are out there is incredibly high by comparison to before lake trout. And so for fishermen, let's face it, getting hooked up with a 22-, 24-, 26-inch cutthroat in a backcountry stream is insane." Word got out. It always does.
The Crowd Problem No One Expected
From Ghost River to Village Green
The recovery of the Yellowstone cutthroat is one of conservation's genuine success stories — a long, expensive, unglamorous grind that paid off in a tangible, measurable way. But success in the backcountry has its own complications. Most people blame the increase in visitation in the Thorofare on the remarkable comeback of the spotted Yellowstone cutthroat trout — though perhaps more accurately, they blame the magazines and filmmakers who broadcast the story around the country. The fish didn't go viral. The idea of the fish did.
The result is something that would have seemed absurd to anyone who'd sweated through the long ride into the Yellowstone Valley even a decade ago. Every direction visitors look, they see people or horses or both. Remote, it turns out, no longer equals isolated. The Thorofare's defining characteristic — its sheer, impassable distance from civilization — now functions more as a sorting mechanism than a guarantee of peace. The determined get in. And there are more determined people than ever.
Bells, Bluetooth Speakers, and 50 Horses
The accounts from regular visitors paint a picture that feels jarring against the mythology of the place. Sam Hochhalter, fisheries supervisor for the Wyoming Game and Fish Department's Cody region, told the story of packrafting into the Yellowstone Valley with friends five years ago, planning to spend several days in the heart of the Thorofare — only to find one camp filled with people target shooting, another blaring music from a Bluetooth speaker, and yet another camp with "50 horses with bells on them all." They left the next day.
Trails along the North Buffalo Fork River on the way into the Thorofare are now one horse-width apart, worn into paired tracks as animals move to avoid the churned mud of the primary path. The land itself is showing the pressure. In a designated wilderness where no mechanized equipment is permitted, the irony is palpable: the place is being loved into a state that starts to resemble its opposite.
Early arrivals in late June find pack strings that once felt novel and even romantic — a line of more than 20 horses and mules winding through stands of lodgepole pine, their black and brown coats glistening with rain, white canvas-covered panniers draped across their backs. By the height of the summer fishing window, those strings are constant. The landscape begins to warn you of horses and people long before you actually see them.
Why It Matters Beyond the Fish
The Irony of Conservation Success
The Thorofare's crowd problem is, at its root, a direct product of doing things right. The Park Service and its partners spent decades and tens of millions of dollars suppressing an invasive species that most of the public had never heard of, in a place most of the public would never visit. The cutthroat came back. Bears returned to the spawning streams. Ospreys began nesting again along drainages that had been eerily quiet for years. And the story became impossible to keep quiet.
This is a pattern that wildlife managers call the "success trap" — a conservation outcome so compelling that it generates the very pressure it was never designed to handle. The Thorofare has no permit system for backcountry camping comparable to some of the more intensively managed corridors in the Greater Yellowstone region. Its boundaries are porous, spread across multiple land management agencies with different rules, different enforcement priorities, and different philosophies about use. A pack string operating from the national forest side plays by different rules than one entering through the national park boundary. Managing the cumulative impact is, practically speaking, an enormous challenge.
The Ecosystem Cannot Run on Vibes
The Greater Yellowstone Ecosystem is one of North America's largest and most important intact ecosystems, and the heart of that ecosystem is the Thorofare region. That centrality matters. The cutthroat trout are not merely a trophy species or a recreational resource — they are a keystone element of the food web, and their recovery has cascading effects on everything from the grizzly bear population to the riparian vegetation along spawning tributaries. The endemic Yellowstone cutthroat population returns to the Thorofare annually to spawn, and bears, eagles, and otters — the entire ecosystem — count on that spawn.
Heavy recreational pressure during the spawn window — typically late June through July — is precisely the kind of disturbance that fisheries biologists worry about most. Horses crossing streams, anglers wading spawning beds, campers clustering near productive fishing holes: each individual impact is minor. The aggregate, repeated season after season across a narrow window of biological vulnerability, is a different calculation entirely. The science has made clear that even with suppression, cutthroat did not achieve conservation benchmarks when incorporating the influence of disease and climate — meaning managers cannot afford to add human disturbance as yet another compounding variable.
What the Future Looks Like
The Case for Managed Access
The question now facing land managers, outfitters, conservation organizations, and the angling public is a genuinely hard one: how do you protect a place whose great selling point is its lack of infrastructure, oversight, and restriction? Permit systems work when they can be enforced, but the Thorofare's multi-agency patchwork makes enforcement complicated. Seasonal closures could protect the most critical spawning windows but would enrage the outfitting industry — a sector that has historically been one of the most effective political allies for wilderness preservation. People who hunt and fish, the theory goes, tend to support costly conservation programs precisely because they have a direct stake in healthy wild places.
There are models from other heavily impacted wilderness areas — limited-entry permits like those used on the Middle Fork of the Salmon in Idaho, or the quota systems applied to some Boundary Waters canoe routes — that could theoretically be adapted for the Thorofare. None of them would be popular. All of them would involve trade-offs. The alternative, doing nothing and watching the place gradually become a crowded parody of wilderness, is arguably worse.
The Window Is Still Open — For Now
Despite the traffic, the Thorofare remains something extraordinary. The Yellowstone cutthroat subspecies is coming back, and fishermen are just starting to realize it — and right now might be the most perfect time to fish the Thorofare. That window will not stay open indefinitely, either because the crowds will make solitude impossible to find, or because the managers will eventually impose the kind of restrictions that a place this ecologically sensitive probably warrants.
Lake trout suppression efforts and improving stream habitat have resulted in an improvement in fish counts, and although numbers haven't fully recovered in this remote region, it is once again an area worth exploring. That careful, qualified optimism from fisheries scientists reflects the real state of play — a place genuinely on the rebound, but one where the recovery is fragile enough that a single bad season, a spike in whirling disease, or a reduction in suppression funding could set things back significantly. Given the high reproductive potential of this lake trout population, managers would regress immediately and likely dramatically if suppression effort were reduced without adequate alternative techniques in place.
For now, the fish are there. The grizzlies are back on the spawning streams. The ospreys are circling again. The cutthroat, in the clearest runs, push through in numbers that would have seemed impossible fifteen years ago. Camping on Atlantic Creek in early July means witnessing cutthroat that migrate that far into the wilderness from Yellowstone Lake in numbers that are simply staggering — if you can find a stretch of bank to yourself.
Getting There and Getting It Right
For anyone serious about making the trip, a few realities bear stating plainly. This is no place for tenderfeet or the ill-equipped, and even from the highest peaks in the area, there is no cellular service. The logistics of a Thorofare expedition — whether on foot or horseback — demand genuine preparation. Weather in the high country can turn violent in July with almost no warning. Grizzly bear encounters are not theoretical. Bears frequently work the area around the ranger station, drawn in by cooking smells. Food storage protocols are not optional.
On the fishing side, the options to explore Yellowstone's headwaters include backpacking in via the Continental Divide Trail from East Entrance Road or from the Heart Lake Trailhead. Each route has its own character and its own challenges. The fishing regulations within the national park differ from those on the national forest side. Cutthroat are the target, and in the current era of recovery, they deserve careful handling — catch-and-release is not just courtesy, it's conservation.
The Thorofare has survived a lot: Army patrols in the 1880s, poachers, wildfires, the near-total collapse of its signature fish species, and now, unexpectedly, its own renewed fame. It is the furthest point from a road in the lower 48 states, and also the backdrop for one of conservation's greatest success stories. Whether it can absorb a surge of popularity without losing what made it worth protecting in the first place is the question its managers, its advocates, and its visitors will be answering — whether they choose to or not — over the next decade. The wilderness is still there. The fish are back. The question is whether the solitude can survive its own restoration.
