Who is Carcajou?
Carcajou patrols a vast Banff snow-country range — from the cirques of Cascade Mountain and Mount Rundle down through the Wapta Icefield country and into the upper Kootenay Valley. Adult male wolverines can hold enormous home ranges, often hundreds of square kilometres, and ADW gives a broad male range of 600-1,000 km2. Carcajou is written as a resident male using a smaller, resource-rich Rockies sector rather than a fixed mapped territory. He moves in long scent-marked loops between cache sites, avalanche paths, and high fir valleys, sometimes covering tens of kilometres in a day.
Tactically he is built for cold-climate punching-above-weight. His dense winter coat sheds snow and slush instead of soaking it up. His paws are broad enough to act like natural snowshoes across deep snowpack. His skull and teeth are built for feeding from frozen carcasses and gripping hard into contested food. Wolverines can contest carcasses with larger carnivores, especially in snow country, but Carcajou’s strength is cost-making and refusal, not magic dominance over every bigger animal.
His one clear personality flaw is a refusal to back down — even from fights he cannot win. Wolverines are famous for stubborn carcass contests and hard winter survival, and Carcajou carries that trait at full expression. The danger is that he commits to encounters where the maths does not favour him — facing a much larger bear, or an opponent on open ground where his snow-mobility means nothing. He has to learn when disengaging is survival, not surrender.
How Carcajou got here
Carcajou was born six winters ago in a snow-tunnel den dug into persistent spring snowpack on a north-facing Mount Rundle slope in Banff National Park. His mother was an adult female whose range covered the Cascade Mountain and Mount Rundle sector. She raised him and his sister through the long mother-cub bond, teaching mountain-range reading, the elk-and-moose seasonal carcass circuit, and the caching trick that turns Banff’s deep snowpack into a natural refrigerator. Carcajou’s sister dispersed south into the Kootenay Valley; Carcajou dispersed north-east and spent two full years in the juvenile-roaming phase before settling on his current range.
By his fifth summer he had taken the Mount Rundle and Cascade Mountain sector as his permanent home territory, and started the adult-male politics of range-overlap negotiation with neighbouring wolverines. The scent-marking vocabulary his mother taught him calibrates his patrol — gland-marked rock outcrops, urine-marked boundary trees, high-relief scrape sites where avalanche paths cut into the forest. His chocolate-brown winter coat carries the pale yellowish-cream “saddle” band that runs from his shoulders across his rump — the individual marking that distinguishes Carcajou from other Banff wolverines in the story world.
The Stoney Nakoda, the Siksika, and the Kootenay First Nations are the traditional custodians of the Banff landscape. The old Algonquian word kwikwahakew gave French Canadian carcajou — the name carried into English across North America. Nakoda traditions frame the wolverine as a trickster figure whose fearlessness and opportunism embody the cold-season survival ethic.
The formative encounter — the one that left the four-claw rake scar across his left shoulder — came in his fourth autumn at a winter-kill moose carcass on a Bow Valley slope above Lake Louise. A mature adult male grizzly displaced him from the carcass. Carcajou had reached it first, cached choice portions into snow-crevice cold storage, and started his usual multi-week feeding pattern. Against an animal many times his size, the site became a contested resource Carcajou could not hold.
The bear arrived at first light. Carcajou was feeding when the bear came down the slope and forced the contest. The usual wolverine response is a snap vocal warning, teeth-bared face-off, then rapid disengage before contact. Instead, Carcajou turned into the pressure for one reckless moment. Wolverines can make carcass contests costly for larger carnivores, especially in winter conditions that favour them — but against a grizzly, the maths does not favour a 30 kg mustelid. The bear’s forepaw connected with Carcajou’s shoulder, leaving four parallel claw lines before the wolverine broke contact and vanished into dense subalpine fir cover. The grizzly took the moose. Carcajou kept the scar.
The scar has stabilised across two years. Four parallel pale lines run diagonally across his left shoulder, visible through the dense winter fur. The encounter taught Carcajou what wolverine instinct does not naturally encode: that against a much larger bear, the punching-above-weight template has an upper limit. Carcajou has not re-engaged a grizzly at a contested carcass since. His scent-marking at high-grizzly-density zones now includes an avoidance window — he reads bear scent before committing to a cache site.
He enters the Savage tournament at 30 kg, six years old, holding the Mount Rundle and Cascade Mountain sector of Banff National Park — and carrying the left-shoulder grizzly-claw rake that defines his adult identity.

Wolverine — that's Carcajou.
Wolverines range across the northern forests of the world — Alaska and northern Canada, Norway, Sweden, Finland, and the Russian Federation from Karelia through Siberia to Kamchatka. Smaller, recovering populations persist in the contiguous United States: the North Cascades of Washington, northern Idaho, western Montana, and Wyoming inside the Greater Yellowstone Ecosystem. They are tied to boreal forest, taiga, subalpine forest, and alpine and high-arctic tundra. Across most of that range they are obligate snowpack denners — reproductive dens require persistent spring snow cover. Lower-latitude populations (Washington Cascades, Yellowstone) survive only at high elevation where spring snowpack is retained. Climate-driven loss of persistent spring snow is the leading long-term threat to southern-edge populations and underpinned the 2023 US listing of the contiguous-US population as Threatened.
Two subspecies are commonly recognised: Gulo gulo gulo (Eurasia) and Gulo gulo luscus (North America). A putative third subspecies, G. g. vancouverensis (Vancouver Island), has been proposed historically but is not supported by current molecular work. Recent phylogeographic analyses show North American and Eurasian wolverines are more closely related than morphological subspecies designations suggest, with post-glacial recolonisation driving much of the observed variation. Within Wyld Rivals, Carcajou (Group H) is framed as a North American G. g. luscus wolverine ranging the Alaskan–North Cascades snow corridor.
The natural nemesis
In the wild, Carcajou's true rival is the Grizzly Bear.
Grizzly Bear — the carcass-site pressure species. Adult male grizzlies massively outweigh wolverines and can displace smaller scavengers from moose, elk, and caribou carcasses across shared Canadian Rockies habitat. Carcajou's 30 kg frame can make a carcass contest costly, especially in snow, but direct combat with a grizzly is unwinnable. His fourth-autumn Bow Valley scar story keeps that biological line clear: he challenged for one reckless moment, the bear took the moose, and Carcajou learned to read bear scent before committing to cache sites.
