The three states of the Central Mississippi River Basin are known for their agricultural production. Arkansas is nicknamed the "Natural State" because of its tall mountains, deep valleys, flowing rivers, dense woodlands, and fertile plains. Iowa produces more corn and hogs than any other state, and plays an important role in the politics of American presidential elections. Missouri, located near the geographic center of the United States, was a starting point for pioneers headed West during the nineteenth century. This book in the LET'S EXPLORE THE STATES series provides information about these three significant states, from their geography, history, and government to their economy, population demographics, and major cities.
