Below is another basic, but more modern, map that shows today's towns. Note that it also shows some changes to the townships (likely after Lake Red Rock was formed by damming the Des Moines river). Here is a brief summary.

If you would like to view a more detailed and modern county map, check out the pdf file for the county that is dated Jan. 1, 2023. It shows the townships as below, but not as clear since all the roads are also listed, but it is a great map if you want to bike the back roads of the county. If you would like a black and white version of this, try here. The gravel roads don't jump out so much.
