The Reality Reports

Formation And Geology: Stone Mountain, located near Atlanta, Georgia, is one of the largest exposed granite formations in the world.  This massive dome, known as a monadnock, was formed around 300 million years ago during the Paleozoic Era.  It originated from magma that cooled deep within the Earth’s crust, solidifying into granite.  Over millions of years, erosion wore away the surrounding softer rock, leaving Stone Mountain as a prominent feature in the landscape.  The granite here is primarily composed of quartz, feldspar, and mica, giving it a unique texture and appearance.
