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:
“Each structure and institution here was so primitive that you could at once refer it to its source; but our buildings commonly suggest neither their origin nor their purpose.”
—Henry David Thoreau (1817–1862)
“All good poetry is the spontaneous overflow of powerful feelings: it takes its origin from emotion recollected in tranquillity.”
—William Wordsworth (1770–1850)
“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)
