The Mound Builders

This work surveys the earthen mounds found in the northwestern riverlands, especially along the Red and Rainy systems, documenting their forms, dimensions, construction methods, and the artifacts unearthed during local excavations. It situates regional mound concentrations, compares them with other mound-bearing areas to the south, and records burial features and structural variants such as stone layers and timber enclosures. The narrative links site placement to agricultural and strategic considerations and evaluates competing theories about the builders and their disappearance, emphasizing the fragmentary evidence and the difficulties of reaching definitive conclusions from dispersed remains.
