Natural Products from the Rainy River Mounds
The Rainy River Mounds yielded significant natural products, including bones, notably skulls that reveal distinct morphological types. Charred wood and birch bark, likely used in burials, indicate the mounds’ use as sacred sites. Earth from the mounds matches the surrounding soil, suggesting a gradual accumulation rather than large-scale construction. Additionally, ochre shows signs of ceremonial use, while metallic ore found near a skull hints at its perceived sacredness. These findings provide insight into the burial practices and cultural significance of the mound builders.
