Georgia’s famous gold bearing lands include the northern and western sections of Cobb County. The top soils are thin over most hills and steep slopes, while much deeper near streams. There are few permanent wetlands paralleling the streams that flow into the Chattahoochee. The section of the Chattahoochee River passing Cobb County generally has a narrow flood plain. This is because high mountains once stood at these locations, but have eroded to large hills through the eons. The Upper Piedmont terrain generally consists of rolling hills and stream valleys, but can seem semi-mountainous. However, it contains several mountains, so some sections of the county are identical in appearance to the Southern Appalachians.
