she guide Lewis and clark through there journey.
They shot deer, turkey and bear. They also picked berries and other fruits. Scagawea helped them plant vegtables that she learned how to grow when she was a Shoshone.
His name was Cameahwait; he was chief of the Shoshone Indians.
I think Lewis and Clark would have gotten lost because they had never been in that area and no clue as to the safest way to get through the mountains. Sacagawea was their guide and she knew how to bypass mountains and avoid dangerous animals therefore keeping Lewis and Clark away from most danger giving them a safe passage to where they wanted to go.
