The water in Lake Michigan started rising gradually, about 6000 years ago. The people who occupied this valley were forced to move to higher grounds because of the constant flooding.
In 1952, Donald Baldwin, a 13-year old boy discovered the mounds accidentally in Copper culture States Park. The copper culture mounds state park is the oldest known burial site in Wisconsin.
Archaeologists pointed out that these Native Americans used a heat treatment process called annealing to extract the copper from the ore they excavated in the region.
There are no camping facilities inside Copper culture Mounds State Park at the moment. You can explore other camping options close to the park, in Oconto town.
All kinds of water sports (swimming, boating, kayaking, rafting, and canoeing) occur on the Oconto River that runs through the park. The river is easily accessible from almost any dimension inside the park.
The trails in the Copper culture state park are isolated. The park does not receive many visitors and you are likely to find yourself enjoying a serene walk in the woods.
There are two duck houses at the Copper Culture State Park. These duck houses were erected by the Association of Bird City Oconto.
