Warren G. Harding launched himself into the White House in 1920 with his famous "front porch" campaign, which he conducted from his Victorian home in Marion, OH. The restored house was built in 1891 and contains almost all original furnishings owned by President Harding and his wife Florence. Adjacent to the Harding Home is a press house used during the 1920 campaign which now serves as a museum dedicated to President and Mrs. Harding's lives. Located two miles from the Home and Museum is the Harding Tomb, a circular monument of white Georgia marble containing the remains of President and Mrs. Harding, set in 10 acres of landscaped grounds.

An individual website for the Harding Tomb can be found here.

The house and museum offer exhibits, tours, and educational programs; the tomb is open to the public.

The Park preserves and interprets the Parkin site on the St. Francis River where a 17-acre Mississippi Period American Indian village was located from A.D. 1000 to 1550. A large platform mound on the river bank remains. There were once many archaeological sites similar to Parkin throughout this region, but they did not survive as eastern Arkansas was settled. Visitors can watch research in progress, and see firsthand the results of careful excavations and laboratory analysis. Along with including an archaeological research laboratory, the park visitor center includes an interpretive exhibit area and auditorium. The park interpretive staff offers audiovisual programs, site tours, workshops, and other educational programs and special events and activities. When archaeological excavations are underway, visitors on guided tours can observe them. Visitors experiencing Parkin Archeological State Park can also tour the circa 1910 Northern Ohio Schoolhouse. By the beginning of World War II, there were 15 one-room and two-room schoolhouses providing education for children in Parkin, a town of less than 2,000 citizens. Today, the Northern Ohio School is the only one of these early Parkin structures still standing. The stories it tells of what took place here in the early 20th century in and around the Sawdust Hill community are parts of the historic fabric of Parkin, just as is the park’s interpretation of the prehistoric village of Casqui.

The site offers exhibits, tours, workshops, and educational and recreational programs and events.

St. Joseph Lead Co. dominated ore production and became the heart of the easter Ozarks' Old Lead Belt, continuing operations in this district until 1972. In 1975, the company donated the 25 buildings of their largest mine-mill complex and the surrounding land to the Missouri Department of Natural Resources. These properties became Missouri Mines State Historic Site and St. Joe State Park. The 19,000 square-foot mine-mill powerhouse has been developed into a large museum that interprets Missouri's mining history and displays old mining machinery and an outstanding mineral collection.

The site offers a short film, exhibits, tours, and occasional recreational and educational events.
