Origin
About 1.08 billion years ago, a large pool of magma formed under what is now central Colorado. Some of this magma worked its way to the surface and formed volcanoes.
After the volcanic activity died away, a large mass of molten magma was left underground. Because the magma was buried about 2 miles (5 km) underground, it took thousands of years for it to cool and this created the granite that we now see on the slopes of Pikes Peak and other areas of the Front Range.
