Mound 88

To the southwest of the Powell Mound, Patrick shows a small mound roughly oval in shape with a northwest axis. A similar mound is shown on the McAdams Map of 1882; he gives a height of 20 feet (6.1 meters). This is probably the same mound, though the McAdams’ location is a bit more difficult to confirm since the scale of his map is not as precise as Patrick’s. It does have the same oval shape with a north-south axis. A mound in a similar location is shown with a height of 10 feet (3.05 meters) on the Thomas Map of 1894. There is no indication of this mound on the 1966 UWM Map since its location was on the edge of the map and the area was being destroyed at that time.

Workers from the University of Illinois at the Powell Mound made a map with a 1-foot contour interval, and it shows a mound with a height of approximately 6 to 8 feet (1.8 to 2.4 meters). This appears to be where Mound 88 would be. There are no published references to Mound 88, and it is now totally destroyed; it is in the parking lot of the discount store mentioned above.
