Archaeology and Cultural Resources

The Dakota Prairie Grasslands have a rich cultural history, reflected in archaeological sites spanning multiple periods, including the Paleoindian, Plains Archaic, Plains Woodland, Plains Village, Equestrian/Fur Trade Era, and Historic Homesteading. Archaeological sites from these different periods provide insights into the past.

What is Archaeology?

Archaeology is the scientific study of the human past through the systematic recovery, analysis, and interpretation of material remains, including artifacts (tools, pottery), architecture, and environmental data. Archaeological sites are locations where these material remains are found.   

Archaeology in the Grasslands

The archaeology mission in the DPG focuses on locating, managing, and interpreting over 11,500 years of human history, from Paleoindian to early European settlement. The program emphasizes the conservation of prehistoric sites, the protection of artifacts, and the provision of educational and interpretive opportunities. Some archaeological sites are investigated for research; this research tends to focus on site types that are not well understood in western North Dakota. 

Key aspects of the archaeology mission include:

  • Site Management: The Forest Service monitors and protects significant archaeological sites from construction, erosion, and vandalism, with a conservation focus.
  • Cultural Resource Documentation: When an archaeological site is discovered, it is recorded and evaluated for potential inclusion in the National Register of Historic Places.
  • Preventing Looting: Educating the public that collecting artifacts, such as projectile points, is prohibited without a permit.
  • Collaboration: The Forest Service works with nine Tribes and the North Dakota State Historic Preservation Office to manage archaeological sites on the Dakota Prairie Grasslands.
  • Interpretation: Developing interpretive, informative sites (e.g., Initial Rock) for the public.
