In the spring of 2024, a homeowner in the Nutana Park neighborhood of Saskatoon was digging in a strawberry patch in her own backyard when her trowel struck something hard. She pulled out a fist-sized piece of gray granite. A groove ran all the way around its middle, like a belt. One end was worn smooth and slightly battered. She had no idea what she was holding, so she brought it to the Saskatchewan Archaeological Society. It was a grooved stone maul, a hammer once mounted to a wooden handle, and used by indigenous peoples on the northern plains for thousands of years. Because it had been found out of archaeological context, there was no reliable way to date this individual tool. Grooved mauls as a tool type were used on the plains for thousands of years, with examples extending back more than 10,000 years. And the stranger part was that the maul wasn't an isolated discovery. Saskatoon sits on an archaeological landscape far older than the city built on top of it. Just north of the city lies Waunoos K. Wynn Heritage Park, where archaeologists have identified 19 pre-contact sites documenting roughly 6,400 years of human activity. For 41 years, archaeologist Dr. Ernie Walker and generations of students excavated this small valley, eventually recovering roughly 200,000 artifacts and other archaeological materials. There are ancient camps here, teepee rings, bison processing grounds, two buffalo jumps, a medicine wheel whose original purpose archaeology still hasn't settled. Bison were returned to Waunoos K. Wynn after roughly 150 years away. And then, after four decades of excavation, the bison did something nobody had planned for. Within a year, their activity, including wallowing in the dirt, exposed something archaeologists had never found here before. It was rock art. What follows are 12 sites, discoveries, and archaeological features in Saskatoon at Waunoos K. Wynn and elsewhere along the South Saskatchewan River. Some are thousands of years old. Some were found almost by accident. And one may suggest that people were living around Waunoos K. Wynn even earlier than the park's oldest confirmed archaeological layers. The uplands north of Waunoos K. Wynn. Two kilometers north of Waunoos K. Wynn's park boundary, on higher ground above the valley, archaeologists have recovered artifacts from the surrounding uplands that suggest something intriguing. This area may have been occupied even earlier than anything found inside the park itself. The materials recovered there point to an occupation time depth of 7,000 to 8,000 years. Which would place people in this landscape 1 to 2,000 years before the oldest confirmed layers at Waunoos K. Wynn. This isn't a confirmed excavation with a name and a Borden number, the way most sites at Waunoos K. Wynn have. It's a scatter of surface material, thinner in documentation than almost anything else on this list. And archaeologists are cautious about how far to push the claim. But the broader region backs up the idea that 7,000-year-old occupation isn't unusual in Saskatchewan. Elsewhere in south-central Saskatchewan, at the Camp Rainer site roughly 135 kilometers south of Saskatoon, in-situ deposits reach back about 7,000 years, into what's called the Terminal Late Paleo-Indian Period. And near Prince Albert, researchers have found evidence that may push local occupation back past 8,000 years. If those surface finds north of Waunoos K. Wynn are confirmed through future professional investigation, the oldest evidence in the area may eventually come from beyond the park boundary rather than inside it. For now, the artifacts remain a footnote rather than a fully excavated chapter. The kind of lead that shows up in a park's own heritage documentation, but hasn't yet been through the years of field work that turned Dogchild or Tipperary Creek into dated published sites. And that's probably the frustrating part. The evidence is there, but until somebody properly excavates it, there's only so much anyone can responsibly say. The Show-Vold site. An hour south of Saskatoon, near the town of Outlook, sits a second site that tells a version of the same story in a different location on a different stretch of the South Saskatchewan River. It's called the Show-Vold site, pronounced roughly Show-Vold, and unlike Waunoos K. Wynn, it isn't a park. It's a research site excavated decades ago and documented in exhaustive detail by two archaeologists, Ian Dyke of the Saskatchewan Museum of Natural History and Richard Moreland of the National Museum of Man, the researcher who would later go on to build Canada's national radiocarbon dating database. Their findings were finally published in 1995 in a massive monograph that remains the definitive account of the site. What Dyke and Moreland found was a campsite used more than 20 separate times over a span of 3,200 years, from around 1850 years before Christ to the year 1350. Layer after layer preserved evidence of the Oxbow, McKean, Pelican Lake, Besant, and Avonlea cultures, each one returning to camp on the exact same stretch of riverbank their predecessors had used centuries earlier. The site was even significant enough to define its own category of artifact. The Outlook Projectile Point, a small early variant of the Besant style, named and classified directly from material recovered here, Show-Vold became important beyond the artifacts themselves. Dyke and Moreland used the site to develop archaeological criteria for recognizing river-crossing campsites, making the geography part of the site's interpretation rather than just its backdrop. The reason people kept coming back, according to Dyke and Moreland, had nothing to do with ceremony or coincidence. It came down to geography. The site sat near the boundary between two ecosystems, the open grasslands and the aspen parkland, giving hunters access to resources from both. It sat close to the Missouri Coteau, a long ridge of hills that served as a natural travel corridor, and most importantly, it sat next to one of the only good river crossings in the entire region. In a landscape where crossing a major river safely could mean the difference between reaching your destination and losing everything to the current, a reliable crossing point was worth returning to, generation after generation, for over 3,000 years. Show-Vold points to the same basic advantage seen at Wahnuskewin. Some places were useful enough that people kept returning to them for as long as those advantages held. Once you understand the geography, 3,000 years of people returning to the same riverbank doesn't seem quite so mysterious. It was simply a very good place to be. The Nutana Park Grooved Mall, which brings the story back to the mall in the strawberry patch. Karin Stoiber, with the Saskatchewan Archaeological Society, examined the tool and confirmed it. That is a very lovely, classic example of a grooved mall, she said. It's got the nice groove going all the way around. It's got some wear on its end. So it's been used, definitely. That discovery in Nutana Park wasn't an isolated fluke. It was a reminder of something archaeologists in Saskatoon have understood for a long time. The modern city sits directly on top of an archaeological landscape that has never been fully mapped. As one expert put it after the mall was examined, as the city has grown and developers have broken ground on new subdivisions, they've repeatedly come across remnants of sites used by indigenous groups long before Saskatoon existed. The mall itself, according to Stoiber's colleague, wasn't the kind of object someone would make in 15 minutes and discard. It would have been hafted to a wooden handle, carried and used repeatedly. A lot of work went into making something like that and then at some point it was lost or left behind, buried under what would eventually become a backyard strawberry patch in a modern subdivision. Saskatoon's own Nutana and Stonebridge neighborhoods have produced indigenous stone tools, points and pottery since local archaeological societies first began surveying the area in the 1960s. Grooved malls, like the one found in the strawberry patch, are not unique to Saskatoon. The Royal Saskatchewan Museum holds comparable hammerstones in its own collection and similar tools recovered elsewhere on the plains have been found at sites dated to more than 10,000 years old, which is part of why archaeologists couldn't narrow down an age for this particular one without more context from the ground around it. Once an artifact is removed without its exact archaeological context being recorded, some of that information, the layer it came from and its precise relationship to nearby material can be lost permanently. The mall is one recent confirmed find and unlikely to be the last. Every excavation, every basement dug, every garden turned over is a chance for the city to run into its own buried history sitting a few centimeters below the surface of ordinary life. And that's what makes this find so interesting. It wasn't discovered in some remote archaeological trench. It was underneath a strawberry patch in Saskatoon. 41 years of archaeology at Wanus Kaewin. Wanus Kaewin is a Cree word that translates roughly to being at peace with oneself. Beginning in 1982, Dr. Ernie Walker led the research that would transform understanding of this valley and under him generations of students and researchers turned Wanus Kaewin into the site of Canada's longest running archaeological dig, ultimately spanning 41 years. Walker has a simple way of putting it. Everybody was here at some point. The site has remained culturally and spiritually significant to indigenous nations across the region including Cree, Nakota, Assiniboine, Dakota, Lakota, Saulteaux, Atsina, and Blackfoot communities. It was formally designated a National Historic Site of Canada in 1986 and opened to the public as a heritage park in 1992. Wanus Kaewin lies in Treaty 6 territory and the homeland of the Métis. The park has also described the property as part of the Historic Lands of the Dakota First Nation. It covers 240 hectares along the South Saskatchewan River where a break in the otherwise flat, exposed prairie drops into a sheltered pocket of trees and rolling ground along Opimihaw Creek. For more than four decades, Wanus Kaewin also served as a training ground for generations of archaeology students. Field schools from the University of Saskatchewan and the Saskatchewan Archaeological Society opened excavation units throughout the valley almost every summer, continuing work that began with Ernie Walker's surveys in the early 1980s. By 2026, that long excavation program had recovered roughly 200,000 artifacts. Andrew MacDonald, the park's co-executive director, has described it as a 41-year archaeological record. Visitors today pass the former dig sites where much of that work took place, now folded into the park's interpretive trails rather than active trenches. At the same time, Wanus Kaewin itself was undergoing a major expansion. In February of 2017, the park launched a $40 million revitalization campaign called Thundering Ahead, announced jointly by Tribal Chief Felix Thomas and Potash Corp. Executive Vice President Wayne Brownlee, with a board chaired by Candace Wasakase Lafferty. The Brownlee Family Foundation alone contributed $5 million to the effort. That campaign funded far more than archaeology, facilities, cultural programming, land stewardship, and the bison restoration program that would, within a few years, expose an entirely new category of evidence at the site. In 2021, the Saskatchewan government added a smaller, one-time grant of $60,000, specifically to fund a coordinator position for the park's bid to become a UNESCO World Heritage Site with the bison rubbing stones. Along the park's walking trails sit several large boulders, unremarkable at first glance, until you notice their surfaces. Smooth, polished in places, with a shallow depression worn into the ground around their base. These are glacial erratics, boulders deposited by the retreating ice sheets somewhere between 10,000 and 15,000 years ago, made of stone that doesn't match anything else in the local bedrock. For most of their existence, they simply sat in the landscape. Then bison started using them. Bison rub against boulders like these to shed their winter coats and relieve the itch of biting insects. Do that often enough, generation after generation, and the stone itself begins to change. Repeated rubbing polishes parts of the surface smooth while trampling and disturbed soil can create a depression around the base. It's a signature that takes centuries to build and can be read by anyone who knows what they're looking at. For decades, these rubbing stones sat as fossils of a behavior that had stopped happening in this valley because the bison themselves were gone from it, driven to the edge of extinction across the entire continent through a combination of commercial slaughter, colonial policy, aimed at destroying the plains bison economy, habitat loss, and disease. Then in December of 2019, that changed. On December 7th, six plains bison arrived at Wanuskewin from Grasslands National Park. Ten days later, five more arrived from South Dakota, with genetic links to the Yellowstone Herd. Eleven animals in total, the first bison to set foot in this valley in roughly 150 years. They were unveiled to the public on January 17th, 2020, and within months, calves were being born on the same land their ancestors had grazed for thousands of years before 19th century slaughter drove plains bison to the edge of extinction. An estimated 26 to 30 million bison once lived across North America. By the end of the 19th century, fewer than a thousand remained. The herd kept growing. By June of 2026, Wanuskewin had more than 60 bison, including 15 calves born that season alone. A restoration project that began with 11 animals had already exceeded the park's earlier goal of building a herd of 50. And with the herd established again, behaviors like rubbing and wallowing returned to a landscape where they had been absent for generations. Newo Asiniyak, the processing site. Not far from those rubbing stones, archaeologists have documented the sites where the animals that didn't survive their encounters with human hunters were taken apart. These are the processing and butchering grounds, and they tell a different part of the story than the kill sites themselves. At the Newo Asiniyak site, the processing area alone contained evidence of seven separate cultural occupations layered over each other across centuries of repeated use, each generation returning to break down bison carcasses in roughly the same spot as the one before it. The work itself left a distinct signature in the ground. Broken stone tools used for skinning, cutting sinew, and scraping hides have been recovered from the processing area at the nearby Miwasin Creek kill site. Fire-broken rock also points to intensive cooking and bone grease rendering, where heated stones could be placed in water-filled pits or hide-lined containers to boil crushed bone and extract its fat. Combined with dried meat and stored food, that kind of processing helped communities preserve far more of a successful hunt for later use. Many parts of a bison could be put to use. Meat could be dried for storage or pounded and combined with rendered fat to make pemmican. Bone became tools and ornaments. Hide became teepee covers and clothing. Sinew became thread and bowstring. The dense concentrations of fire-broken rock, bone, and tool fragments found in these processing areas point to repeated episodes of intensive processing rather than a single use of the site. And the Sunburn Teepee Ring Site. Higher up on the valley's cooler, breezier terrain sits the Sunburn Teepee Ring Site, where archaeologists documented multiple stone rings. Walker excavated one of them in 1988. What is most visible today is a circle of stones roughly matching the size and shape of a teepee's base. Mobile groups carried most of their shelters, tools, and belongings with them when they moved. But the heavy stones used to anchor teepee coverings stayed behind, along with small traces of everyday life such as bone, charcoal, and discarded material. Interpreters at the park explained the location choice in practical terms. This higher ground, cooler in summer and exposed to more consistent wind, kept mosquitoes at bay, making it a logical place to camp during the warmer months. It's a small, functional detail, but it tells you something about how deliberately people chose where to live at different times of year, weighing insect exposure and temperature the same way anyone camping today might. A teepee ring on its own can look almost unremarkable. A loose scatter of fist-sized to head-sized stones in a rough circle a few meters across, easy to walk past without noticing. But the placement of those stones is precise enough that archaeologists can estimate the size of the shelter that once stood there. The ring walker excavated preserves the footprint of what was once somebody's home. Wolf Willow, the sheltered campsite. That seasonal logic runs in the opposite direction, lower in the valley, where the steep banks of Opimaha Creek offered shelter that summer camps on the exposed uplands never needed. Archaeologists have interpreted evidence at the Wolf Willow site as belonging to groups either following bison herds through the colder months or settling in for the winter itself, taking advantage of terrain that blocked prairie wind and offered shelter unavailable on the open ground above. Walker has described the deep, steep-sided valley as providing shelter that was especially valuable during winter. Protection that simply wasn't available on the flat, wind-scoured plains above. Winter survival on the northern plains was not a passive matter of waiting out the cold. It meant choosing terrain carefully, stockpiling processed meat from the previous season's hunts, and managing fuel and shelter. Saskatchewan winter temperatures can fall below negative 30 degrees Celsius, with wind across open prairie making exposed ground far harder to survive on for extended periods. A valley bottom that blocked even part of that wind could make a meaningful difference. The teepee rings on the breezy uplands and the deeper, sheltered camps in the valley bottom tell the same underlying story. People who understood exactly what this terrain offered and when. Dogchild, Wolf Willow, and Tipperary Creek. Taken together, those sites show an extraordinary pattern. People used this small valley repeatedly for roughly 6,400 years across nearly every major pre-contact cultural group recognized on the northern plains. The archaeological question is what made this small valley useful enough to draw so many different groups back across such a long span of time. The deepest and most detailed record of that pattern comes from the Dogchild site, where occupation extends back nearly 6,000 years across six distinct occupation levels spanning five separate cultural complexes. Plains side-notched, Prairie side-notched, Duncan and Hannah, Oxbow, and two separate levels of the much older Mummy Cave complex. Excavated between 2004 and 2009, its deepest layer, labeled level 3b, contained 24 projectile points and the remains of roughly 10 bison. One of those bones, a bison metacarpal, returned a radiocarbon date of approximately 5,900 years, making it one of the oldest confirmed dates recovered anywhere inside the park. Nearby, the Wolf Willow site preserves four separate occupation levels of its own, spanning the plains side-notched, Prairie side-notched, McKean, and Oxbow complexes, dated to roughly 500, 1,000, 3,000, 300, and 4,600 years ago respectively. And at Tipperary Creek, one of the very first sites documented in the park, excavators have identified 20 distinct occupation levels stacked on top of each other in a single location. Across the whole park, researchers have now recovered roughly 200,000 artifacts and other archaeological materials, stone tools, pottery shards, teeth, bone fragments, shell, charcoal, and preserved seeds, each one a small data point in a 6,400-year record of repeated return. The explanation researchers keep coming back to is a matter of concentrated resources. As the continental ice retreated from this region roughly 12,000 years ago, melt water and the developing South Saskatchewan drainage helped shape the landscape that would eventually become the Opimaha Valley, cutting a sheltered, wooded pocket into the middle of an otherwise open, exposed prairie. In a landscape with few trees, unpredictable wind, and limited natural shelter, a valley like this would have stood out as a rare and valuable resource. Water, shade, wildlife, and protection from the elements all concentrated in one place. Groups moving across the open plains would have been able to see it from a distance and known exactly what it offered. For groups moving seasonally across the plains, the combination was hard to beat. Reliable water, shelter from the wind, vegetation, and access to game, different cultural traditions separated by centuries could recognize the same advantages. During the warmer, drier Middle Holocene, a period archaeologists often associate with peltothermal, some researchers once proposed that parts of the northern plains experienced a major occupation hiatus. That theory, first proposed by researcher Brian Reeves in 1973, has since been challenged by later excavation data, and the current evidence increasingly points toward repeated use of the valley across roughly 6,400 years rather than a full-scale, prolonged abandonment. What the strata at Dogchild, Wolf Willow, and Tipperary Creek make clear is that across changing climates and changing cultures, something about this specific stretch of riverbank kept pulling people back to camp and hunt here. The Wānu's Kewin Buffalo Jumps. The largest and most organized hunts at Wānu's Kewin took place at the Buffalo Jump Cliffs. The park contains two of them, the Apamihaw Jump and the Newo Asiniaq site. Wānu's Kewin's buffalo jump landscape was used by indigenous peoples of the northern plains across different periods. Traditions associated with the broader valley include Blackfoot, Cree, Ojibwe, Assiniboine, Nakota, and Dakota peoples. The Apamihaw Jump has been dated to roughly 2,300 years ago. Newo Asiniaq, meaning four stones in Cree, was first identified by Ernie Walker in the early 1980s and later excavated in 1984 and 1985, revealing two probable kill layers at the base of a roughly three meter cliff, along with a processing area containing seven distinct cultural occupations. And all of it was done without horses. Horses didn't reach the northern plains until roughly 300 years ago. These communal hunts were organized on foot against an animal that could weigh close to a thousand kilograms and outrun a human easily over open ground. Hunters built drive lanes out of stone cairns at comparable jump sites on the northern plains, sometimes stretching well over a kilometer or two, funneling toward the cliff edge like a narrowing chute made of piled stone rather than fencing. Accounts of traditional plains buffalo jump hunting describe runners using disguises, often wolf or coyote hides, and carefully coordinated movement to manipulate a herd into stampeding toward the edge. Whatever precise techniques were used at Wanuskewin specifically, the surviving drive lanes show that these hunts demanded planning on a remarkable scale. The approach to Wanuskewin's interpretive center actually follows one of these ancient drive lanes, bringing visitors along the same route once used to funnel bison toward the jump. At Nawo Asiniak, the kill area lay below a drop of roughly three meters. Three meters doesn't sound like much. You might expect a buffalo jump to be a dramatic cliff, but it didn't need to be. The hunt depended on momentum, a tightly packed herd, uneven ground, and animals piling into one another once the front of the herd went over the edge. A successful communal hunt could provide enormous quantities of meat, fat, hides, bone, and sinew for later use. At Nawo Asiniak and the associated processing areas, archaeologists have recovered fire-broken rock from bone grease rendering, stone tools used in butchering, and imported material like Knife River flint, carried from what is now North Dakota, evidence of trade networks stretching hundreds of kilometers beyond the valley itself. A single successful jump could kill dozens of animals at once, more meat than any small group could process on the spot, which is exactly why the processing grounds sit close by. It was in every sense a coordinated operation, requiring planning, teamwork, and detailed knowledge of bison behavior passed down across generations. The Juanes K. Wynne Medicine Wheel, on a ridge in the park's southwest corner, with an unobstructed view over the South Saskatchewan River, sits the feature that has puzzled researchers longer than almost anything else at Juanes K. Wynne. The Medicine Wheel. Believed to have been built roughly 1,500 years ago, it's one of fewer than 100 known medicine wheels documented anywhere on the northern plains, and the northernmost one ever recorded. At its center sits a stone cairn roughly 7 meters in diameter. Around it runs an outer ring approximately 13 meters wide. Scattered around the site sit at least five smaller cairns, positioned between 1 and 17 meters from the central structure, along with additional loose boulders inside the ring itself. Many medicine wheels documented elsewhere on the plains include spokes, lines of stone connecting the central cairn to the outer ring, often interpreted as having astronomical or calendrical significance, marking solstices or star risings. Juanes K. Wynne's medicine wheel has no spokes at all, and according to research summarized in Canadian Geographic, there don't appear to be any astronomical alignments associated with this particular wheel either, the kind of solar or stellar markers that have helped explain the layout of other medicine wheels elsewhere in North America. No surviving written account identifies its original purpose, and archaeology alone has not settled the question. This is one of those places where archaeology reaches its limit. You can measure every stone perfectly and still not know exactly what the people who placed them there intended. The site itself wasn't formally rediscovered by researchers until the 1930s. Walker recalls that University of Saskatchewan professors once drove out on Sunday afternoons and held tea parties at the medicine wheel, a striking contrast with the way the site is treated today. Today that treatment has changed entirely. Local indigenous communities visit the medicine wheel to leave offerings, sing, and hold ceremonies, and visitors to the park are asked to view the structure only from a respectful distance. Jake Sanderson, an elder from James Smith Cree Nation, has described its meaning in spiritual terms that go beyond archaeology entirely. I describe it as a gift from a creator. The spokes were points to different sacred places on Turtle Island and the world. Today, those meanings remain alive through the indigenous communities who continue to use the site for ceremony. The Newo-Asiniaq petroglyphs, the most recent chapter in Wanuskewin's 6,400-year story, began appropriately with the bison themselves. After the herd's reintroduction in December of 2019, the animals were left to roam and graze freely across sections of the park, doing what bison naturally do, wallowing in loose dirt to coat themselves in dust, a behavior that helps regulate body temperature and ward off insects. Within a year of the herd's return, that wallowing exposed something decades of careful, methodical human excavation had never found—rock art. Archaeologists investigating the discovery then excavated the surrounding area and found three more petroglyphs nearby. The find was publicly announced in 2021. Archaeologists recovered four separate petroglyphs from the site in total. The largest was a boulder weighing 544 kilograms, its surface covered in a network of carved lines. Nearby sat a stone weighing roughly 340 kilograms marked with a distinct grid pattern. A third stone, smaller and roughly the size of a football, bore a pitted and grooved surface, and a fourth was a 225-kilogram boulder carved with the image of a bison rib. Buried close by, at a depth of only about 10 centimeters, researchers found a stone knife believed to be associated with the carvings. Based on comparable rock art traditions elsewhere on the plains, this style, known as the hoofprint tradition, has been dated to somewhere between 300 and 1,800 years old, with researchers estimating the Wanoos K-Win examples likely fall around 1,000 years old. Ernie Walker put the significance of the find simply, what we didn't have was rock art, and all of a sudden we're in the rock art business. For me, this is the best part of the entire story. Archaeologists had worked at Wanoos K-Win for decades. Then the bison came back, disturbed the ground, and revealed an entire category of evidence nobody knew was there. Some indigenous knowledge keepers connected to the park have described the discovery as fulfilling long-held expectations that the bison's return would bring the land back to life in ways researchers hadn't anticipated. In 2021, Siksika artist Adrian Stimson took up an artist residency at Wanoos K-Win. Work emerging from that period engaged with the bison, the land, and the newly discovered petroglyphs, part of how the find became woven into the park's living relationship with the nations who still consider this valley significant. Wanoos K-Win's next chapter is already underway. Added to Canada's tentative list for UNESCO World Heritage status in 2017, the park is working toward becoming Saskatchewan's first UNESCO World Heritage Site. Wanoos K-Win's current timeline calls for the final nomination dossier to move through Parks Canada in 2026 with World Heritage Committee consideration targeted for 2028. Walker has acknowledged that Wanoos K-Win doesn't have the kind of monumental architecture that makes some heritage sites immediately legible. There are no pyramids here, no great walls or cathedrals. Wanoos K-Win's case rests on something less visible. The density of archaeological evidence preserved across one small landscape and the living cultural relationship indigenous peoples continue to have with it today. That density is what ultimately makes Wanoos K-Win unusual. One small landscape preserving evidence associated with nearly every major pre-contact cultural group recognized on the northern plains, while a reintroduced bison herd helped expose carvings that four decades of archaeological excavation had never revealed. It's a valley that has been pulling people back to the exact same stretch of riverbank since long before Rome was founded. Whatever else eventually turns up, whether in a future study of the uplands to the north or in the next Saskatoon backyard, the 6,400 year record at the center of it all is no longer in question. Only how much of it is still left to find. And before you go, you can now watch or listen to us on Spotify too. Scan the QR code on screen to follow us there. Thanks so much for watching.
