In her novel "Sacajawea" (1984), Anna Lee Waldo explored the story of Sacajawea's returning to Wyoming 50 years after her departure.
Prepričanje, da je Sacagaweja res doživela visoko starost in umrla v Wyomingu je možno zaslediti v biografiji z naslovom "Sacagawea", ki jo je pod vodstvom profesorice in zgodovinarke Grace Raymond Hebard izdala University of Wyoming.
