In this book I shall build further on Irving's apt cast iron metaphor, which has meaning far deeper than even he might have imagined. Although they do not compose a single forest, but a complex mosaic of forests interspersed with prairies, the Cross Timbers constitute an impressive geographical feature. Seen on a satellite photo, the Cross Timbers run in a generally north-south direction across a large area that includes portions of southern Kansas, eastern Oklahoma, and north central Texas. We now recognize that the unique forest that Irving experienced was actually vast in extent and covered portions of what would later become three states.

In his travels to the western frontier in the early 1830s, American writer Washington Irving characterized the Cross Timbers as 'forests of cast iron.' Irving used this colorful metaphor to emphasize the toughness of the vegetation that he encountered-a nearly impenetrable forest of stunted oak trees. Many historical and contemporary maps and photographs illustrate the text. He then traces the interaction of people and the landscape, from the earliest Native American inhabitants and European explorers to the developers and residents of today's ever-expanding cities and suburbs. Richard Francaviglia opens with a natural history that discusses the region's geography and geology, vegetation, and climate. This landmark book fully describes the natural environment of the Cross Timbers and the role that people have played in transforming the region. Home to Native Americans over several thousand years, the Cross Timbers became a barrier to westward expansion in the nineteenth century, until roads and railroads opened it up to farmers and ranchers, coal miners, and modern city developers, all of whom changed its character in far-reaching ways. A complex mosaic of post oak and blackjack oak forests interspersed with prairies, the Cross Timbers covers a north-south belt of southern Kansas, eastern Oklahoma, and North Central Texas.
