I found this fascinating bit of history about Nazekaw Point on the Effigy Mounds National Monument Facebook page: "The town of Nazekaw: Did it exist? In 1856, two speculators from Prairie du Chien, Bernard W. Brisbois and Herculus Dousman, purchased property at the mouth of the Yellow river from the federal government. The speculators created the paper town of Nazekaw (also known as Nazeka and Nazekaw) on the south bank of the Yellow River, and sold the surrounding lots to farmers. Multiple sources indicated the town included a post office, stockyard and gristmill between 1858 and 1862; however, other sources claim this is a “mythical” town that was only laid out on paper. We may never know if it did exist, but if visitors hike our South Unit trail, they can visit Nazekaw Point, which is a beautiful overlook of the mouth of the Yellow River and think about what might have been."

The Yellow River Boardwalk Trail leads down the hill from the Effigy Mounds National Monument visitor center, through a tunnel under State Highway 76, through a riparian wetland, and onto a bridge that crosses the Yellow River. There are lovely views of the confluence of the Yellow River with the Mississippi River, and wildlife viewing is good as well. While there, we were entertained by a Red-headed Woodpecker (see iPhone photo) who almost seemed to purposefully greet and keep us company as we walked along the trail. Completing the Yellow Boardwalk Trail earned an Effigy Mounds National Monument Hiking Challenge patch (See photo), celebrating the monument's 75th anniversary.
