Mammoth Spring serves as the focal point of this region, where the state line between Arkansas and Missouri divides the towns of Thayer and Mammoth Spring. The landscape is defined by the winding course of the Spring River, which flows southward through a series of significant river features including Cottonwood Falls, Saddler Falls, and the Needles Eye near Horseshoe Bend. The drainage network is dense, fed by numerous tributaries such as Myatt Creek, English Cr, and Wolf Cr.
