FutureStarrPiedmont Region of Georgia OR
From the cattle industry to forestry to the film business, the Piedmont Region of North Georgia has had a deeper connection with the South than any other region of the state. Plus, it’s easy to get to.
Since the Piedmont did not spend millennia under the ocean, its rocks were not washed into sand. So, we can get a great idea of the geological history of Georgia from the Piedmont region. Some of the rocks in this region predate the Appalachian Mountains themselves, one of North America's oldest mountain ranges at roughly 500 million years old. This ancient geologic history helped promote the conditions for certain minerals, and Georgia actually had its own gold rush back in the early 1800s.
The Piedmont is a plateau region located in the Eastern United States. It is situated between the Atlantic coastal plain and the main Appalachian Mountains, stretching from New York in the north to central Alabama in the south. The Piedmont Province is a physiographic province of the larger Appalachian division which consists of the Gettysburg-Newark Lowlands, the Piedmont Upland and the Piedmont Lowlands sections.

Piedmont soils are generally clay-like (Ultisols) and moderately fertile. In some areas they have suffered from erosion and over-cropping, particularly in the South where cotton was historically the chief crop. In the central Piedmont region of North Carolina and Virginia, tobacco is the main crop, while in the north region there is more diversity, including orchards, dairying, and general farming.
The surface relief of the Piedmont is characterized by relatively low, rolling hills with heights above sea level between 200 feet (50 m) and 800 feet to 1,000 feet (250 m to 300 m). Its geology is complex, with numerous rock formations of different materials and ages intermingled with one another. Essentially, the Piedmont is the remnant of several ancient mountain chains that have since been eroded. Geologists have identified at least five separate events which have led to sediment deposition, including the Grenville orogeny (the collision of continents that created the supercontinent Rodinia) and the Appalachian orogeny during the formation of Pangaea. The last major event in the history of the Piedmont was the break-up of Pangaea, when North America and Africa began to separate. Large basins formed from the rifting and were subsequently filled by the sediments shed from the surrounding higher ground. The series of Mesozoic basins is almost entirely located inside the Piedmont region. (Source: en.wikipedia.org)
