Tennessee, Alabama & Georgia Railway
1946 Geological Map

The TAG ran along the eastern base of Lookout Mountain and Pigeon Mountain in an area in which it might be said that geology is on full display. The two mountains, actually a single 80-mile long plateau, are composed of Paleozoic sedimentary rocks formed in a variety of ancient environments. Hundreds of millions of years of deposition, uplift, folding, faulting, and erosion produced a spectacular landscape of high cliffs, rocky canyons, and scenic valleys. For a better understanding of the processes involved, see Roadside Geology of Georgia by Pamela J.W. Gore and William Witherspoon, published in 2013.
