State parks are parks or other protected areas managed at the sub-national level within those nations which use "state" as a political subdivision. State parks are typically established by a state to preserve a location on account of its natural beauty, historic interest, or recreational potential. There are state parks under the administration of the government of each U.S. state, some of the Mexican states, and in Brazil. The term is also used in the Australian states of Victoria and New South Wales. The equivalent term used in Canada, Argentina, South Africa, and Belgium, is provincial park. Similar systems of local government maintained parks exist in other countries, but the terminology varies.

Fort Davidson, a fortification near the town of Pilot Knob, Missouri, was the site of the Battle of Fort Davidson during the American Civil War. Built by Union Army soldiers during the American Civil War, the fort repulsed Confederate attacks during the Battle of Fort Davidson on September 27, 1864, during Price's Raid. That night, the Union garrison blew up the fort's magazine and abandoned the site. A mass grave was constructed on the site to bury battlefield dead. After the war, the area was used by a mining company, before passing into private hands and eventually the administration of the United States Forest Service. In 1968, the Battle of Pilot Knob State Historic Site was created as a Missouri State Park. The fort itself was added to the National Register of Historic Places in 1970. As of 2020, a visitors center containing a museum is located within the park. The museum contains a fiber optic display, as well as artifacts including Brigadier General Thomas Ewing Jr.'s sword. The fort's walls are still visible, as is the crater created when the magazine was detonated. A monument marks the location of the mass grave.
A Smithsonian trinomial is a unique identifier assigned to archaeological sites in many states in the United States. Trinomials are composed of a one or two digit coding for the state, typically two letters coding for the county or county-equivalent within the state, and one or more sequential digits representing the order in which the site was listed in that county. The Smithsonian Institution developed the site number system in the 1930s and 1940s, but it no longer maintains the system. Trinomials are now assigned by the individual states. The 48 states then in the union were assigned numbers in alphabetical order. Alaska was assigned number 49 and Hawaii was assigned number 50, after those states were admitted to the union. There is no Smithsonian trinomial number assigned for the District of Columbia or any United States territory.
