Sacajawea was a Native American woman who helped guide Lewis and Clark on their long trip from near St. Louis toward the Pacific Ocean in the early 1800s. She was Shoshone, and she knew the land, the rivers, and some of the people they would meet. She travelled with a baby on her back. She died in 1812, still young; nobody is sure of her birth year, which is why you sometimes see a question mark. History books do not all spell her name the same way. Sacajawea is one old spelling; many writers now prefer Sacagawea, and in some places you will see Sakakawea. The name is not an English word in origin. People remember her as a guide and a peacemaker on that crossing of the American West, though actually later writers have argued over how much she led the way and how much she helped by talking and translating. For a student, the core is enough: she is the famous woman on that journey.
