Indian Mounds of Wis 2d Ed.png

New Edition of Indian Mounds of WisconsinThe University of Wisconsin Press has published a new edition of the popular Indian Mounds of Wisconsin written by archaeologists and mound experts Robert Birmingham and Amy Rosebrough. First published in 2000, the new edition contains much new and updated material and images. The book includes exciting new research and information on the spectacular effigy mounds, an archaeological world wonder, and the great Mississippian civilization as represented by the ancient town of Aztalan near Lake Mills, among other topics. The cover of the book features a photograph of platform mounds at Aztalan State park taken by Dan Seurer of Lake Mills. A lengthy appendix provides an expanded list of ancient Indian mound sites that can be easily visited by the public. Books will be available for purchase for $25 at the Annual Membership Meeting and Dinner on January 27, 2018, where one or both authors will gladly sign your copy. It will also be available at the park trailer.

Donations for the Aztalan Interpretive Center are greatly appreciated and will contribute to its success. Elizabeth Parker has generously extended her matching donation through 2017 to help build the much needed visitor center at the park. Her match is a dollar for dollar donation for monies raised by the Friends of Aztalan State Park. The matching donation comes from the trusts of George S. Parker II of the Parker Pen Company, Janesville WI.

Interpretive Center

In September 2014 The Friends of Aztalan State Park awarded the RFP for initial design of the Interpretive Center.

In July 2015 Dimension IV Madison Design Group submitted its final design report.

In 2016 The Friends of Aztalan State Park solicited ideas for the design of interpretive displays in the Interpretive Center.

In 2017 The Friends of Aztalan State Park sent a RFP for interior design of the Interpretive Center.

The Friends will also be hosting fund raisers to provide funds for the remaining phases of constructing the Interpretive Center. See the Events page for dates and places of upcoming fund raisers.

This is an exciting new milestone for the Friends group.  Interested parties will be invited to participate in in-person and on-line discussion and survey sessions to help make this project a success.  

Check back often for information on how you can participate in these sessions, and to follow the progress of our efforts to bring this project to fruition.
