Most of the Arkansas Delta ranks among the lesser scenic regions of the Natural State.
But the monotony of the flat landscapes inland from the Mississippi River is broken by the distinctive geological intrusion of Crowley's Ridge.
Varying from 1 to 12 miles wide, the ridge rises 250 feet above the flood plain. Along its crest runs a National Scenic Byway, so designated in 1998. Crowley's Ridge Parkway extends 218 miles north from Helena-West Helena, with the last 10 miles going into Missouri. It shifts among more than a dozen federal, state and county roads on its way through eight Arkansas counties.
