At Campbell's Island, located in the Mississippi River near present-day Rock Island, a day-long battle was fought in the War of 1812. On July 19, 1814, a pro-British band of Sauk Indians led by Black Hawk attacked a force of United States regulars and rangers under Lieutenant John Campbell. The Americans were defeated, with the loss of 16 American lives. Campbell's Island State Memorial consists of a North Carolina granite monument dedicated in 1908, in a mini-park overlooking the river.

The Lewis and Clark Expedition arrived at the Mandan-Hidatsa Indian villages on the Upper Missouri River on October 25, 1804. They found the Mandan people very hospitable and decided to remain at this wintering site until the spring thaw when they would resume their up-river journey. On November 3, William Clark made a simple entry in his journal, "We commence building our cabins." These cabins formed part of an enclosure that was christened Fort Mandan in honor of their hosts. As it turned out, Fort Mandan was occupied longer than any of the three winter posts used by the expedition. Reconstructed Fort Mandan rests in the riparian forests of the Missouri River. The refurnished rooms of this full-size replica depict the equipage of the Lewis and Clark Expeditio. On-site interpreters provide programs and year-round tours of Lewis and Clark's 1804–1805 wintering post. The Interpretive Center provides an overview of the Lewis and Clark Expedition, with special emphasis on the time spent at Fort Mandan. The displays include Native American artifacts, a buffalo robe visitors will be able to try on, as well as a "cradle-board" much like the one Sakakawea may have used to carry her baby. An authentic wood canoe carved from the trunk of a large cottonwood tree demonstrates the winter preparations the Expedition made while at Fort Mandan.

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

The Miamisburg Mound is the largest conical burial mound in the state of Ohio and possibly in the eastern U. S. Archaeological investigations of the surrounding area suggest that it was constructed by the prehistoric Adena Indians (800 BC–AD 100). Built on a 100-foot-high bluff, the mound measures 877 feet in circumference. It was originally more than 70 feet high. Visitors may climb the 116 steps from its base to the summit for a view of the surrounding park.

Fort Towson was established in 1824 in response to a need to quell conflicts between lawless elements, Native American peoples, and settlers claiming the area as part of Arkansas Territory. The fort also served as an outpost on the border between the United States and Texas, which at that time was part of Mexico. Connected to the East by road, Fort Towson served as a gateway for settlers bound for Texas during the 1830s. Those passing through the area included Sam Houston, Davy Crockett, and Stephen F. Austin. When the Choctaw and Chickasaw were displaced from their lands in the Southeastern United States, the fort served as a point of dispersal upon their arrival in the west. The fort was also an important staging area for U.S. forces during the Mexican War of 1846. Fort Towson was abandoned in 1856 when the frontier moved west. During the Civil War, however, it served for a time as headquarters for Confederate forces operating in Indian Territory. In 1865 General Stand Watie surrendered his command near the fort to become the last Confederate general to lay down arms.
