Fort Jefferson Park and Monument mark the site of an advance outpost of General Arthur St. Clair, built in October 1791. It was named in honor of Thomas Jefferson, then Secretary of State. One of a chain of defensive forts built to protect army supplies from Indians, it served as a supply base throughout the campaigns of General St. Clair and General Anthony Wayne. It was abandoned in 1796. The monument is made of faced granite field boulders, six feet square and 20 feet tall. No part of the fort remains.

The site 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.

Mastodon State Historic Site contains an important archaeological and paleontological site—the Kimmswick Bone Bed. Bones of mastodons and other now-extinct animals were first found here in the early 1800s. The area gained fame as one of the most extensive Pleistocene Ice Age deposits in the country and attracted scientific interest worldwide. Today, the 425-acre property preserves this National Register of Historic Places site and provides recreational opportunities. A museum tells the natural and cultural story of the oldest American Indian site one can visit in the state's park system. A full-size replica of a mastodon skeleton highlights the exhibits. A picnic area, several trails, and a special-use camping area offer chances to explore the land where the lives of Native Americans and mastodons once intertwined.

The site offers exhibits, a slideshow, tours, and educational programs.
