Check out this beautiful drone video of a famous river canyon in the mountains of northern Georgia, compliments of contributor JerzDrone. Tallulah Gorge is formed by a river of the same name in the North Georgia Mountains, part of the Appalachian chain. The canyon is 3 km (around 2 mi.) long and up to 300 meters (1k ft) deep, and features a series of waterfalls. One of the official Seven Wonders of Georgia, the gorge and falls were used to film a portion of the classic 1972 thriller Deliverance.
