The Delta region is bisected by an unusual geological formation known as Crowley's Ridge. A narrow band of rolling hills, Crowley's Ridge rises from 250 to 500 feet (150 m) above the surrounding alluvial plain and underlies many of the major towns of eastern Arkansas.
Northwest Arkansas is part of the Ozark Plateau including the Boston Mountains, to the south are the Ouachita Mountains and these regions are divided by the Arkansas River; the southern and eastern parts of Arkansas are called the Lowlands. All of these mountains ranges are part of the U.S. Interior Highlands region, the only major mountainous region between the Rocky Mountains and the Appalachian Mountains. The highest point in the state is Mount Magazine in the Ozark Mountains; it rises to 2,753 feet (839 m) above sea level.
Arkansas is home to many caves, such as Blanchard Springs Caverns. It is also the first U.S. state in which diamonds were found (near Murfreesboro). Arkansas has the only operating diamond mine in the United States.
