(Iowa)
Palisades-Kepler State Park is a 840-acre (340 ha) state park in Linn County, Iowa, United States, near the city of Mount Vernon. The park is located in a forested area on the bank of the Cedar River marked by bluffs and ravines. While the state created the park in 1922, it was greatly expanded in 1928 through the estate of Louis H. Kepler and further developed in the 1930s by the Civilian Conservation Corps (CCC).
