This 45 minute PowerPoint presentation is full of graphics that help viewers grasp the extraordinary significance of these mysterious monuments of the ancient world.


Jarrod Burks on “Imaging Technology in Earthwork Exploration”Snake Den Magnetic Data-Burks 2007

Jarrod with Mag1Modern archaeologists have tools that allow them to research historical sites without excavation. Archaeologist Dr. Jarrod Burks is a leading surveyor of ancient earthworks sites in the Midwest. He uses an array of modern, noninvasive technology to produce images that allow him and others to “see” underground, sometimes finding earthworks or features previously unknown to science. These  images are important for earthwork conservation, scientific research, and educating the public about these precious ancient monuments. This 45 minute PowerPoint presentation contains many fascinating images showing the results of his research on earthworks. Dr. Burks also presents how these images are created, and how they can be used to learn more about the construction of these mysterious earthwork sites, as well as give insights into the extraordinary Native American culture that built them.
