Mound 22 is shown on Patrick’s map to be a large, conical mound; it is part of a triangle made by Mound 22 on the west, Mound 24 on the east, and Mound 23 on the north. He suggests that Mound 22 was a large, oval-to-round platform mound. The base of Mound 22 is at an elevation of 129 meters (423.2 feet) and is located between N268 298 and E841-876 on the UWM Map. Its north-south dimension is 30 meters (98.4 feet) and its east-west dimension is 35 meters (114.8 feet). These measurements conform very well with Patrick’s description of a slightly oval form with its major axis east-west. The top elevation of the mound today is 129.5 meters (424.8 feet), giving it a height of 0 .5 meters (1.6 feet) . Both McAdams and Thomas show 15-foot (4.6 meters) heights, while the Peterson-McAdams Map of 1906 shows only 5 feet (1.5 meters).
