When Lewis and Clark made their way through what is now North Dakota, the Shoshone Indian woman named Sacajawea joined the team of explorers. Because the expedition was traveling with a Native American, other tribes did not attack the group. In fact, one tribe even supplied horses to help the explorers and their interpreter cross the Rocky Mountains. This invaluable team member taught the men how to find medicine and food in the wilderness and once even saved the records of the journey when a canoe overturned during a storm. She reached the Pacific Ocean with Lewis and Clark in 1805. Her fame eventually spread; one of the best-known monuments to her is a statue in Portland, Oregon.
