Not far from where I live is a geological oddity. Stone Mountain is a bald and rounded mass of granite a mile and a half long and nearly a thousand feet high. Eons ago, molten rock pushed up from the earth’s core to the surface, then bubbled out and hardened into a monolith. Given the flat landscape around it, what one notices first about Stone Mountain is how unexpected it is. This isolated mass of stone stands all alone, sticking out like a blister on a thumb. It is as if an unneeded chunk of the Rockies was carelessly tossed over the shoulder of the Creator and landed improbably in a Georgia pasture.
