3. Timeline of Mound Building Cultures in Ohio Adena: 800 BC to 100 BC Hopewell: 200 BC to 500 AD Fort Ancient Tradition (Mississippian): 1000 AD to 1500

4. Mound Destruction The Need for Preservation

5. Study Areas and Major Rivers of Ohio

6. Resources Used in this Study 1. Early maps of Hopewell mounds and earthworks retrieved from: Squier, E. G., & Davis, E. H. (1848). Ancient Monuments of the Mississippi Valley (Classics in Smithsonian Anthropology). Smithsonian Books. 2. Modern orthorectified aerial photography (Tiff Format) and Lidar data (las. format) available from the State of Ohio Office of Information Technology (2011), Ohio Geographically Referenced Information Program. 3. ODOT (Ohio Department of Transportation) shapefiles for Airport, Active Rail, City, County, Interstate, State Routes, Township, and US Routes. 4. DNR (Department of Natural Resources) hydrography shapefile of Ohio‘s water sources, and divide line between Lake Erie and the Ohio River. 5. USGS (United States Geological Survey) aerial photographs from the late 1950's and 1960's, as well as SRTM DEMs.
