Hightower-Jasper Ridges District

 

Although the Hightower Ridges and Jasper Ridges have different structural and lithologic histories, they are topographically so similar that they may be discussed together. The Hightower-jasper Ridges District consists of a series of low, linear, parallel ridges separated by narrow valleys. The Hightower Ridges range in elevation from 1500 feet in the northeast to 1000 feet in the southwest. Relief in this area varies from 500 feet in the northeast to 200 feet in the southwest. The Jasper Ridges bisect the McCaysville Basin District and continue southward as a low area between the Cohutta and Blue Ridge Mountains. These ridges range in elevation from 2400 feet in the north to 1200 feet near Canton, where they join the Hightower Ridges. Relief varies from 800 feet in the north to 200 feet near Lake Allatoona. Some structural control of streams in the district is exhibited by the modified rectangular drainage patterns. The southern and western boundaries are located where there is a decrease in the density of the linear ridges.
