What role did Sacagawea play in the Lewis and Clark Expedition?

Sacagawea played a crucial role as both an interpreter and guide during the Lewis and Clark Expedition. Her ability to communicate with various Native American tribes was invaluable, as she helped the expedition negotiate and foster goodwill with the indigenous peoples they encountered. Additionally, her knowledge of the terrain and resources available in the region assisted the explorers in navigating through challenging landscapes.

While some might consider options such as scout, supplier of maps, or leader, these roles do not align closely with her actual contributions. Sacagawea did not serve as a scout who individually surveyed the land ahead, nor did she create maps. Moreover, although she was vital to the success of the expedition, Lewis and Clark were the official leaders. Her unique position as an interpreter and guide was instrumental in establishing connections with Native American tribes, which ultimately facilitated the success of the journey.
