where did the blue ridge mountains get their name
Blue Ridge Mountains The Blue Ridge Mountains are noted for having a bluish color when seen from a distance. Trees put the "blue" in Blue Ridge, from the isoprene released into the atmosphere,[2] thereby contributing to the characteristic haze on the mountains and their distinctive color.[3]
Stone Mountain Stone Mountain is a pluton, a type of igneous intrusion. Primarily composed of quartz monzonite, the dome of Stone Mountain was formed during the formation of the Blue Ridge Mountains around 300â€“350 million years ago (during the Carboniferous period), part of the Appalachian Mountains.[6] It formed as a result of the upwelling of magma from within the Earth's crust. This magma solidified to form granite within the crust five to ten miles below the surface.
