The story
Fort Abraham Lincoln State Park spreads along the Missouri at Mandan, North Dakota, and its ground holds two histories told with equal weight: On-a-Slant Village, the earthlodge town of the Mandan Nation that thrived here for two centuries before smallpox and change emptied it — reconstructed lodges now interpret Mandan life first and respectfully — and the 1870s cavalry post from whose commanding officer's quarters Lt. Col. George Custer led the 7th Cavalry out in May 1876 toward the Little Bighorn, where Lakota, Cheyenne and Arapaho warriors defending their people destroyed his command — history stated factually, both perspectives honoured. The Custer House is a faithful reconstruction on the original footprint, toured in costume, and it carries the park's telling: interpreters and visitors describe footsteps on the porch and stairs, a woman's presence associated in telling with the grieving household of 1876, lights after hours, and parade-ground figures — undocumented accounts the park's seasonal ghost tours collect. Present the park as layered ground — Mandan centuries first, cavalry years after — its house telling the lightest layer. Details from North Dakota state park pages.
