The author of Streams to the River, River to the Sea uses Sacagawea as the narrator to provide a different perspective on the Lewis and Clark expedition. Through Sacagawea's narration, the reader gains insight into the experiences and emotions of a Native American woman during the expedition. Unlike Lewis and Clark's account, Sacagawea's perspective highlights the challenges and injustices faced by Native Americans at the hands of white settlers. For example, Sacagawea describes the discomfort she feels when white men handle her infant son without her consent, revealing the lack of agency and respect afforded to Native women. Additionally, Sacagawea's narration allows for a deeper understanding of the complex relationships and negotiations between different Native American tribes and the expedition. By including Sacagawea's perspective, the author expands the story beyond the white male perspective and provides a more nuanced portrayal of the expedition.
