Native American earthworks

Native American earthworks are large-scale structures built by indigenous peoples using natural materials like soil, stone, and clay. These constructions include mounds, ditches, causeways, and circular or geometric forms, often serving ceremonial, burial, or territorial purposes. They reflect advanced engineering and spiritual practices, with some like the Hopewell in Ohio or the Mississippian Mound Builders creating complex sites that demonstrate social organization, cosmology, and connection to the land. Today, they stand as important cultural heritage sites, offering insights into the sophisticated civilizations and traditions of Native American communities before European contact.
