Crowley's Ridge

Crowley's Ridge

Crowley’s Ridge received its name from Benjamin Crowley, the first settler to reach the area around 1820.  Crowley’s Ridge is an oddity geologists still find somewhat baffling. The prevailing theory now is that Crowley’s Ridge is a remnant of land left from a time when the ancestral Mississippi and Ohio Rivers flowed on its two sides eroding away surrounding land and leaving the Ridge in the middle.  Over the ages that followed, deposits of wind-blown soil, known as loess, accumulated there.  Crowley's Ridge rises up from 250 to 500 feet above the alluvial plain of the Mississippi embayment in a 150 mile line from southeastern Missouri to the Mississippi River near Helena.  This narrow rolling hill region rising above the flat delta is the sixth, and smallest, natural division of the State of Arkansas.  This unique, crescent-shaped ridge boasts plants found nowhere else west of the Mississippi River, along with many beautiful native wildflowers and cacti.  Crowley’s Ridge is one of only two such formations in the world.
