Hello, I'm an expert in American history, particularly the period of westward expansion. Let me provide you with information about the Indian woman associated with the Lewis and Clark Expedition.

The Indian woman you're referring to is Sacagawea. She was a Shoshone woman who played a significant role in the Lewis and Clark Expedition, which was an overland journey from the United States to the Pacific Ocean between 1804 and 1806. Sacagawea was hired by the expedition as an interpreter because she spoke both the Hidatsa language, which was the language of the Mandan tribe at Fort Mandan, and her native Shoshone language, which was crucial for the expedition's interaction with the Shoshone tribe to secure horses for the journey.

Sacagawea was also notable for being the only woman in the expedition, and she made an invaluable contribution by helping to establish peaceful relations with the Native American tribes they encountered. Additionally, her presence was believed to have facilitated trade and communication with the tribes, as her presence with a baby (she gave birth to her son, Jean Baptiste Charbonneau, during the expedition) was seen as a sign of peaceful intentions.
