About this map

Nickajack Lake and the wide bend of the Tennessee River dominate this landscape, where the waters divide the terrain between the Cumberland Plateau to the west and Walden Ridge to the east. The Sequatchie River carves a fertile valley through the center of the sheet, supporting a string of communities including Sequatchie, Nickletown, and Ebenezer. This 2019 survey illustrates the complex geography of Marion County, where steep-walled hollows like Powder Mill Hollow and Shingle Mill Hollow descend toward the river bottomlands.

Transportation and infrastructure are central to the area's layout, anchored by the Marion County Airport-Brown Field and the Marion Memorial Bridge crossing at Rankin Cove. To the south, industrial and rail-adjacent sites like Vulcan and Ladds sit near the base of Sand Mountain. Natural features like Pryor Cave Spring and the distinctive Grays Bluff provide landmarks for those studying the intersection of the river's path with the ancient geology of the Tennessee Valley.
