AGS / Education / Geology Resources / Physiographic Regions / Arkansas River Valley


The Arkansas River Valley is a low-lying region surrounding the valley of the Arkansas River and its major tributaries.  The highest point in Arkansas (Mount Magazine – 2753 ft.) is found among several mountain ridges that rise above the lowlands in the southern portion of the river valley.  The mountain ridges are separated by broad valleys. Surface rocks in this region consist of a sequence of coal-bearing sandstones and shales.  To learn more about the geology click here.
