In this article, the author aims to "discover" the actual Sacajawea. She intends to produce work that critiques colonialism in history and museums and to return the focus of the colonial gaze back to the colonizer. In this article, she talks about how colonial narratives of Sacajawea in popular culture justify conquest, heteropatriarchy, and the expansion of the United States while supporting the continued colonial management of Native peoples, erasure of Native national identities, and theft of Native lands. Currently, many of the visual representations of Native peoples are in films. Specifically, the author focuses on representations of Sacajawea in the film "Night at the Museum" (2006) in order to deconstruct how Native peoples, and Native women in particular, are represented in modernity as Denise da Silva's affectable subjects facing obliteration by the horizon of death. She ends this article with a play written by Monique Mojica that counters the negative representations of Sacajawea as a means of offering a critique of colonial representations and narratives of Sacajawea.
