This group of conical mounds is a short walk from the visitor's center.
This path leads up to several groups of mounds within Effigy Mounds NM. We didn't get to see any of them because the bus could not (and did not try to) travel on the back road leading to them.
Over at Pikes Peak SP, the Bear Mound was a short distance from the parking lot. Here's part of the mound, mainly the lower part of the "bear".
Some archaeological tourists take a walk around the "bear".
Pikes Peak is set on a bluff above the Mississippi, and thus included some great viewing areas. This view looks north, with Prairie du Chien, Wisconsin in the background.
Looking east, we could see a railroad bridge span the mouth of the Wisconsin River as it empties into the Mississippi.
