An Expedition West

Lewis and Clark were dutiful on their mission from Thomas Jefferson to learn about the animals and people living in the new territory of the Louisiana purchase and beyond.  On their journey they discovered new animals like the prairie dog and plants like Lewis' monkey flower.  Friendly Indians, like the Mandans and the Nez Perce helped them find food and shelter along the way.  The Shoshone Indians guided them through the treacherous Rocky Mountains.  Lewis and Clark's expedition West gained valuable information for the United States of America.
