Location of Dolliver Memorial State Park in Iowa

Dolliver Memorial State Park is a state park of Iowa, US, featuring high bluffs and deep ravines on the Des Moines River. The park is located 10 miles (16 km) south of Fort Dodge and 3 miles (4.8 km) northwest of Lehigh.[2] The park contains two listings on the National Register of Historic Places: Dolliver Memorial State Park, Entrance Area (Area A) and Dolliver Memorial State Park, Picnic, Hiking & Maintenance Area (Area B).


Dolliver Memorial State Park is on the west bank of the Des Moines River at the mouth of a small tributary called Prairie Creek. The creek has eroded through a 100-foot (30 m) high bluff, exposing a cross section of sandstone deposited by a Mesozoic river. Known as the Copperas Beds, these formations exhibit petrified wood and mineral deposits of calcite and sulfur left from water filtering through the rock.[2]


At the north end of the park is a narrow ravine named Boneyard Hollow. Early settlers found numerous bones of bison littering the ravine. It is thought that prehistoric Native Americans either stampeded bison into the ravine from a buffalo jump or herded them into the confined space from the riverbank, where they killed and butchered the animals. There are also several Indian mounds within the park.[2]

In 1915 eleven-year-old Ruth Peterson discovered a lead tablet at the mouth of the creek outside Boneyard Hollow. The Latin inscription stated that the tablet had been left by explorers claiming the area for France in 1750, and mentioned Father Louis Hennepin by name. With the potential to rewrite European exploration of Iowa, the "Hennepin Plate" attracted a great deal of attention. Edgar Harlan, curator of the Iowa state archives, led an investigation. However the poor Latin and the fact that Hennepin had died in 1706 cast doubt on the tablet's authenticity. Ultimately two local boys admitted to making the tablet as a prank in 1913.[3] As a result of the hoax, though, Harlan had become interested in the scenic area and helped spark public interest in preserving it as a state park. The property was purchased for $38,500 and dedicated in 1925 as Iowa's third state park, after Backbone and Ledges.[4] Ruth Peterson died in 2004 at the age of 100, and in 2007 her son and other relatives donated the tablet to the Webster County Historical Society.[3]


The campground features 33 sites, all with electrical hookups, plus 2 camper cabins, modern restrooms, showers, and a holding tank dump station. There is a separate group camp with a dining hall, restrooms, and showers. Two lodges built in the 1930s and an open picnic shelter can be rented for private events.[2]


The park provides a boat ramp for river access. An interpretive trail follows Prairie Creek to the Copperas Beds and then leads up to the wooded blufftops.[2]
