Lewis and Clark had to think ahead and plan for times when wild game would be unavailable or in short supply. Their keelboat was stocked with nearly 7 tons of dry goods, including flour, salt, coffee, pork, meal, corn, sugar, beans and lard.
Lewis and Clark met Charbonneau and quickly hired him to serve as interpreter on their expedition. Even though she was pregnant with her first child, Sacagawea was chosen to accompany them on their mission. Lewis and Clark believed that her knowledge of the Shoshone language would help them later in their journey.ewis and Clark met Charbonneau and quickly hired him to serve as interpreter on their expedition.
