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.

Famous quotes containing the word origin:
“Though I do not believe that a plant will spring up where no seed has been, I have great faith in a seed,—a, to me, equally mysterious origin for it.”
—Henry David Thoreau (1817–1862)
“Good resolutions are useless attempts to interfere with scientific laws. Their origin is pure vanity. Their result is absolutely nil. They give us, now and then, some of those luxurious sterile emotions that have a certain charm for the weak.... They are simply cheques that men draw on a bank where they have no account.”
—Oscar Wilde (1854–1900)
“For, though the origin of most of our words is forgotten, each word was at first a stroke of genius, and obtained currency, because for the moment it symbolized the world to the first speaker and to the hearer. The etymologist finds the deadest word to have been once a brilliant picture.”
—Ralph Waldo Emerson (1803–1882)
