Sacagawea was a native-american indian who led the Lewis and Clark expedition across America. She gives them various tips on how to survive, including how to scare a mountain lion. Although, by the end of their expedition, she became upset about Lewis and Clark acts and abandons them. Moments later, she is threatened by a mountain lion, but the explorers saved her life by using one of the tips she gave them. When they reached the Pacific ocean (where is now Eugene, Oregon), they honor her by creating the Sacagawea dollar, which can be exchanged by a real dollar in a bank.
