It has been called “one of the best preserved and most diverse Effigy Mound groups in Wisconsin.” Each mound group is located on an elevated landform suggesting an almost island-like setting, unique for mound groups associated with the Effigy Mound ritual complex. Thus, its unusual setting adds to its significance. Further, the Lizard Mound site is the only one of the three district sites located on public land, affording greater protection for both mound and off-mound areas of the site. The site has a diversity of mound forms and one of the largest assemblages of preserved mounds in the region, and is the largest surviving collection of bas-relief, earthen mounds with water and water spirit symbolism on earth.
