This is the story of the Guadalupe Mountains National Park in Texas, and its place in the history of the first stagecoaches that carried mail to the American West. There used to be a time when the quickest way to travel across the western United States was in a stagecoach. A stagecoach was a large, enclosed wagon pulled by teams of horses or mules. The driver tried for a speed of about five miles an hour. So, in 1857, Congress offered to help any company that would try to deliver mail overland to the West Coast. A man named John Butterfield accepted this offer. He developed plans for a company that would carry the mail -- and passengers, too.
