Knife River Indian Villages National Historic Site
North Dakota
A major Hidatsa/Mandan trade hub for centuries -- Lewis and Clark stopped here in 1804 and met Sacagawea nearby -- where you can still see the visible circular depressions of earthlodge villages pressed into the prairie itself, no reconstruction needed. The visitor center holds an extraordinary artifact collection and a full-size earthlodge replica you can walk into.
Why Roamward picked it
A true hidden gem -- a lesser-visited NPS unit near Stanton, off US-83 between the I-94 corridor and US-2, deepens the Lewis & Clark storyline started at Fort Mandan and gives Roamward a Native-history site with intact (not rebuilt) archaeological ground.
