The Sequatchie Valley is the defining geographic feature of Marion County. Stretching roughly southwest-to-northeast through the southeastern Cumberland Plateau, it is one of the longest continuous valleys in the eastern United States. Marion County forms the valley's southern end; Sequatchie and Bledsoe counties lie to the north.

Geology

The valley is a classic breached anticline: the original uplifted ridge eroded through its limestone core, leaving a long linear valley with steep rock-face walls rising 1,000 feet or more on either side. Terrain through Marion County is characterized by dissected uplands, steep escarpments, narrow alluvial bottoms along the Sequatchie River, and bluffs above the Tennessee River Gorge where the valley meets the river.

The Sequatchie River

The valley takes its name from the Sequatchie River, which flows northeast-to-southwest down the valley floor before emptying into the Tennessee River near Jasper. The name comes from a Cherokee word (variously rendered Siquatchi or Se-qua-cha-ha-hok), generally interpreted as meaning "opossum" or referring to the river's meandering path.

Settlement pattern

The valley was home to Cherokee towns before European settlement and later became a ribbon of American settlement following water sources and easier terrain. Farming, small towns, and communities cluster on the valley floor and along its slopes. Jasper, Whitwell, Kimball, South Pittsburg, Sweeten's Cove, and the community named Sequatchie all lie in the Marion County portion of the valley.

Sequatchie Valley National Scenic Byway

The Sequatchie Valley National Scenic Byway runs through Marion, Sequatchie, Bledsoe, and Cumberland counties, following the valley between Walden's Ridge and the Cumberland Plateau. Jasper is one of the byway's signature stops.
