The Dividing Ridge - Composite of 1915 and 2015 Images

This image is a composite of a 2015 Google map and the 1915 Dividing Ridge Group Plate 2 image from the 1915 Wisconsin Archeologist Vol.14 No.3, between pages 84 and 85. The original plate image of the dividing ridge was drawn in 1859 by Dr. Increase A. Lapham. The following link will take you to that image:

In using the above link, scroll to page 83 to read the text about the Dividing Ridge Mound Group.

 

Since the 1915 image was not drawn to scale, I have done my best to resize and skew the original image to best fit the map. Compare this image to a related image in this Flickr photo album which is a composite of a 2015 Google map and a 1901 topographic map of Lake Monona which shows the dividing ridge as a topographic feature. The 1901 topographic map scale is a little rough so I also had to resize and skew the image to best fit the Google map. I hope someday to update both of these composite images with better versions. Currently the northwest portion of the image with the mounds illustrated is slightly out of position with the topographic map as they relate to each other and the Google map. I will have to research Photoshop help to better to fix this.

 

These composite images were created to help people better visualize the size and location of these Native American mounds. I wish so much that they would have been saved from destruction.
