Norton Mound Group

The Norton Mound Group consists of eleven preserved earthen mounds near the Grand River, ranging from 30 to 100 feet in diameter. The site covers 55 acres and has been systematically examined through archaeological work to document the structures and objects within.

The mounds were built around the first century AD during the Hopewell civilization period. This era was known for creating large ceremonial and burial complexes across North America.

The mounds served as shared burial and gathering places for Hopewell peoples. They reflect spiritual beliefs visible today through how objects and remains were arranged within the earthen structures.

The site is managed by the Grand Rapids Public Museum but remains closed to public access to protect the archaeological record. You can view the mounds from outside to understand their scale and arrangement without disturbing the site.

The mounds display layered construction using black dirt, ash, and natural sod, showing sophisticated understanding of materials and durability. This careful layering was necessary to create stable structures that would endure over centuries.
