Devils Tower National MonumentThe process began about 50 million years ago. Magma (molten rock) was injected into layers of sedimentary rock, forming the Tower one and one-half miles below the earth's surface. It has since taken millions of years to erode away the surrounding sedimentary rock to expose the Tower we see today.
