Mesas are capped with hard rock that is often basalt and have horizontal strata. In the process of erosion the hard rock acts as a flat protective cap preserving the regions between stream valleys or other places where erosion is especially active, in the form of, table-mountains or fortress-hills. Many examples are found in Spain, North and South Africa, the Bad Lands and Colorado regions of North America, in Arabia, India and Australia. The largest mesa in the world is considered to be the Grand Mesa in western Colorado in the United States.
