In northeastern Iowa, Effigy Mounds National Monument protects over 200 prehistoric earthen mounds, many depicting animal forms such as bears or birds. These were constructed between 500 BC and 1200 AD by indigenous moundbuilders of the Woodland period—some as burial sites, some with ritual significance. The site lies above the Mississippi River in a geologically unique region that remained ice-free during the last ice age and was settled early on. Today, the preserve is part of the National Park Service and an important site of cultural remembrance.

The visitor center is a great place to begin your exploration of Effigy Mounds National Park. There is an exhibit that describes the natural and human history of the area. There is a small bookstore. And if you are into collecting National Parks cancellation stamps, you can also get those. In addition, this is the starting point for all the trails in the North, South, and more recently acquired Heritage areas of the park.

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.
