Question: What is the age of these mountains that start in the northeast corner of Georgia and had the Georgia Gold Rush spread throughout it in 1829?
Sentence (from "North Georgia mountains"): At over 1 billion years of age, the Blue Ridge mountains are among the oldest mountains in the United States and sometimes mistaken to be the oldest mountains in the world (they are only about one third of the age of South Africa's 3.6 billion year old Barberton greenstone belt.)
