Some see the monument as “the largest shrine to white supremacy in the history of the world.” By Debra McKinney, Southern Poverty Law Center — From its north side, Stone Mountain is a formidable sight. Staggeringly steep, nearly five times as high as Niagara Falls, it rises from Georgia’s wooded landscape like a rogue wave. This anomalous, igneous dome east of Atlanta is the centerpiece of a state park that draws 4 million visitors a year. Forty stories above ground, front and center on the gunmetal-gray face of the stone, is the largest bas-relief carving on the planet, a Civil War memorial to Jefferson Davis, Robert E. Lee and Thomas “Stonewall” Jackson. These leaders of the Southern rebellion against the United States sit astride their steeds, hats over their hearts, on a three-acre backdrop etched into the mountainside.
