The above map contains educated guesses as to where the different Mandan and Hidatsa villages were located when Lewis and Clark visited them for the first time. As you can see, Sacagawea's village was on the Knife River, a tributary of the Missouri River. Also, notice the different spelling of her name: Sakakawea. There are three spellings recognized as correct: (1) Sacajawea (2) Sacagawea and (3) Sakakawea. All are acceptable. I will post more about this later.
