Yes, the Driftless Region has the highest concentration of these kinds of mounds in the world. Wouldn’t you like to know more about them?
This page had that information, but I am revising it. However, the most comprehensive guide I know of, put together over many, many years, is here. On the main page, not only are you directed to many of the mound sights that have been preserved, but given a recommended reading list.
But if you enjoyed our early page on the large mounds in the area, including the Platte or “M” Mound parts one and two, you’ll also enjoy this piece. The large mounds–Platte Mound, Belmont Mound, Horseshoe Mound, Sinsinawa Mound–are not the same things as the much smaller conical, linear, and effigy mounds, those these small, and in many ways more fascinating, mounds can occur on top of the larger ones.
