The final report on the first ever remote sensing project over the ancient town of Aztalan that provides details of what major archaeological features still lie underground. The project was conducted by Ohio Valley Archaeology, Inc. in cooperation with the University of Wisconsin-Milwaukee, the University of Wisconsin-Madison, Wisconsin DNR, and the Friends of Aztalan State Park. The full report, plus images, can be accessed here.
