AAA Editor Notes
Fort Abraham Lincoln State Park, 7 mi. s. on the Lewis and Clark Trail/SR 1806, is located at the confluence of the Heart and Missouri rivers. It encompasses the site of Fort Abraham Lincoln, an infantry and cavalry post from which Lt. Col. George Custer led the 7th Cavalry to the Battle of the Little Bighorn in 1876.

The reconstructed complex consists of the commissary, granary, stables, enlisted men's barracks and the house where Custer stayed. The visitor center contains artifacts pertaining to Native American and military history and items recalling the fur trade, railroad and homesteading eras.

The ruins of On-a-Slant Village, occupied by the Mandan Indians for more than 2 centuries, are within the park. Meriwether Lewis and William Clark camped near the abandoned village while exploring this area on their momentous westward expedition in the early 19th century.
