"WebThe basalt dikes eroded faster than the surrounding Conway granite, creating a deepening valley where the gorge is now. The gorge was covered by glaciers during the Ice Age, but the ice sheet did not greatly change the surface. It partially filled the valley with glacial debris and removed soil and weathered rock from the vicinity. " - Basalt dike
