This historic site in North Dakota was an interesting visit. Small but well- done museum with a replica Mandan earth lodge on the grounds. Also a walking trail down to the river by the former sites of 5 villages. I have included a link to their website with several very good videos on the Mandan People. Lewis and Clark met Sakajawea in this area and she, along with her husband and baby, joined the Corp of Discovery as interpreters and guides.
