During the summer of 1805, Lewis and Clark were desperate to find the Shoshone. They needed to buy horses to get them over the Rocky Mountains before winter.
On July 22, Sacagawea began to recognize landmarks. She told the captains that up ahead were the three forks of the Missouri, where three smaller rivers come together to form the Missouri. This news made the group happy. A few days later, they reached the three forks. Sacagawea told them this was where her people had been camped when she was kidnapped by the Hidatsa. Lewis wrote in his journal, “She does not... show any distress at these recollections, or any joy at the prospect of being restored to her country.” He would soon see how wrong he was.
