The park was created in 1934 when 160 acres (65 ha) of land were donated under the sponsorship of Ponca Legion Post 117.[4] In 1934, the Civilian Conservation Corps began developing the site.[5] The park and town bear the name of the Ponca tribe, who inhabited the area before European settlement, and whose chief, Standing Bear, won a celebrated court battle to have the Indian declared a "person" under U.S. law.[6]
Twenty-two miles of hiking and biking trails wind through the deep ravines and hilltop ridges of the park. The Three State Overlook offers a scenic blufftop view of Nebraska, Iowa, and South Dakota. An interactive museum at park headquarters includes exhibits about the Missouri River and its history. The park offers a fishing pond, swimming pool, campgrounds, and cabins.[3]
