Frequently asked questions
What is the highest point in Georgia?
Brasstown Bald at 4,784 ft (1,458 m), from USGS, Elevations and Distances in the United States (highest and lowest elevations) (revised edition 2001).
What is the lowest point in Georgia?
Atlantic Ocean, at sea level, per the USGS Elevations and Distances table (2001).
What is the average elevation of Georgia?
About 508 ft (155 m): the mean of USGS 3DEP elevations at 229 points on a regular grid about 26 km apart inside the state boundary. It is our estimate, not a published figure.
Which Georgia city on this site is highest?
Atlanta, at 1,050 ft downtown (USGS). The lowest is Augusta at 141 ft.
Does altitude affect cooking in Georgia?
At 508 ft, water boils at about 211.1 °F (99.5 °C) and standard air pressure is 29.38 inHg (995 hPa), so each breath holds about 98% of the oxygen it would at sea level. That is for the state's average elevation; check your own town, because Georgia spans 4,784 ft from lowest to highest.
