Walking a riverbank five kilometres north of Prince Albert, Saskatchewan, avocational archaeologist Dave Rondeau noticed something that didn't belong to any recent century. Erosion along the North Saskatchewan River had peeled back the soil, exposing layered stratigraphy that told him people had been here and had been here for a long time. "The moment I saw the layers of history peeking through the soil," he later said, "I felt the weight of generations staring back at me." What Rondeau had found in 2023 has since been confirmed as one of the oldest known Indigenous sites on the North American continent, and the implications reach well beyond Saskatchewan.
