Annual Bus Tour

This year's Friends of Aztalan fall field trip will be to one of the state's largest effigy mound groups, the remarkable Cranberry Creek mounds that comprise the Cranberry Creek Archaeological Mound District, near Necedah, Wisconsin. It is also a State Natural Area.  Over 300 mounds are found in two adjacent groupings. One huge grouping consists longlines of conicalmounds with a few key effigy mounds. The other includes many  unique and intriguing effigy mounds that include birds, bears,  and odd, elongated bear- like creatures,  New LIDAR imaging(below)  revealed many more mounds than previously known to have existed so we can examine new mounds that have never been mapped. LIDAR imaging is revolutionizing archaeology in the world since satellite or airborne lasers just map the surface of ground, including ancient constructions, essentially cutting through foliage that obscure the ancientfeatures, in this case mounds.   Our guide will bearchaeologist Robert (Ernie) Boszhardt who gave us thewonderful tour of  Trempeauleau archaeological sites earlier in the year. Mr Boszhard is the expert on the Cranberry Creeksince he helped coordinate the modern mapping of the mounds and discovered an adjacent associated ancient campsite.

The field trip will be Saturday,  October 1  and we will travelby van(s) or bus depending on the number of people who register. We will meet at 8:00 AM  at  the DNR Glacial Drumlin State Trail headquarters (the old depot) 1213 S. Main St.on the west side ofLake Mills  where people can leave their cars. However, we can also pick uppeople at the Dutch Mill Park and Ride on East Broadway just offthe Beltline in Madison since it is on the way. Soda and water will be provided, but please bring a bag lunch. We expect to return by 4:30 PM . Cranberry Creek is about a 2 1/2hour trip fromLake Mills . The mounds are located on level ground near roads, so the tour will not involve strenous walking. We will be hiking through some forested areas,.however.
