There are four โextantโ (still visible) mound groups you can visit on the main campus, all but one of them located within the boundaries of the Lakeshore Nature Preserve. Recently these mound groups were surveyed and entered in a special burial sites catalog maintained by the Wisconsin Historical Society. The label associated with each location includes a number used in the state Archaeological Site Inventory (ASI) maintained by the Wisconsin Historical Society. The site surveys establish a 25-foot preservation buffer around the mounds.

The falls is very busy, but it is beautiful. Like most falls it's amazing to see in the different times of year, especially winter with a good snow fall. This falls keeps going during the winter.

Great place to visit, although definitely the most crowded place in the park. Like most falls, also a fun place to see in the winter when things are freezing and snow covers the ground.

Around 2,000 years ago, local inhabitants initiated the burial of their dead in the sacred mounds that scatter across the Point. At one time, Picnic Point boasted seven mounds, but relic hunters destroyed one mound before 1912. Today, the Preserve harbors numerous burial mounds and other ancient archaeological sites, reflecting the rich history and cultural significance of the area.
