Fort Fred Steele was established on June 20, 1868 and occupied until August 7, 1886 by soldiers who were sent by the U.S. Government to guard against attack from Indians. The construction of the Transcontinental Union Pacific Railroad across southern Wyoming 1867–1869, in turn, brought the cattlemen, sheepherders, loggers, tie hacks, miners, and merchants who changed the wasteland into Wyoming Territory. Colonel Richard I. Dodge, who selected this site on the west bank of the North Platte River, named the fort for Major General Frederick Steele, 20th U.S. Infantry, a Civil War hero.

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.
