Geography

Boundaries

Beginning from the Atlantic Ocean, the state's eastern border with South Carolina runs up the Savannah River, northwest to its origin at the confluence of the Tugaloo and Seneca Rivers. It then continues up the Tugaloo (originally Tugalo) and into the Chattooga River, its most significant tributary. These bounds were decided in the 1797 Treaty of Beaufort, and tested in the U.S. Supreme Court in the two Georgia v. South Carolina cases in 1923 and 1989.

The border then takes a sharp turn around the tip of Rabun County, at latitude 35°N, though from this point it diverges slightly south (due to inaccuracies in the original survey). This originally was the Georgia and North Carolina border all the way back to the Mississippi River, until Tennessee was divided from North Carolina, and the Yazoo companies induced the legislature of Georgia to pass an act, approved by the governor in 1795, to sell the greater part of Georgia's territory presently comprising Alabama and Mississippi.

The state's western border then departs in another straight line south-southeastward, at a point southwest of Chattanooga, to meet the westernmost point of the Chattahoochee River near West Point. It continues down to the point where it ends at the Flint River (the confluence of the two forming Florida's Apalachicola River), and goes almost due east and very slightly south, in a straight line to the origin of the St. Mary's River, which then forms the remainder of the boundary back to the ocean.

It should be noted that the water boundaries are still set to be the original thalweg of the rivers. Since then, several have been inundated by lakes created by dams, including theApalachicola/Chattahoochee/Flint point now under Lake Seminole.

Georgia state legislators have claimed that the state's border with Tennessee has been erroneously placed one mile (1.6 km) further south than intended in an 1818 survey, and in 2010 proposed that the border should be corrected. This would allow Georgia, then in the midst of a significant drought, to access water from the Tennessee River.

Geology and terrain

Each region has its own distinctive characteristics. For instance, the Ridge and Valley, which lies in the northwest corner of the state, includes limestone, sandstone, shale and other sedimentary rocks, which have yielded construction-grade limestone, barite, ocher and small amounts of coal.Main article: Geology of Georgia (U.S. state)

Flora

The state of Georgia has approximately 250 tree species and 58 protected plants. Georgia's native trees include red cedar, a variety of pines, oaks, maples, cypress, sweetgum and scaly-bark and white hickories, as well as many others. Palmettos and other subtropical flora are found in the southern and coastal regions. Yellow jasmine, and mountain laurel make up just a few of the flowering shrubs in the state.

Fauna

White-tailed (Virginia) deer are in nearly all counties. The northern mockingbird and Brown Thrasher are among the 160 bird species that live in the state.

Reptiles include the eastern diamondback, copperhead, and cottonmouth, salamanders, frogs, alligators and toads. There are about 79 species of reptile and 63 amphibians known to live in Georgia.

The most popular freshwater game fish are trout, bream, bass, and catfish, all but the last of which are produced in state hatcheries for restocking. Popular saltwater game fish include red drum, spotted seatrout, flounder, and tarpon, among many others. Porpoises, whales, shrimp, oysters, and blue crabs are found inshore and offshore of the Georgia coast.
