Yule Marble is a type of metamorphed limestone found only in the Yule Creek Valley, in the West Elk Mountains of Colorado, just south of the town of Marble, Colorado (39°4?20?N 107°11?22?W? / ?39.07222°N 107.18944°W? / 39.07222; -107.18944). Quarried today at 9,300 feet above sea level, Yule Marble is famous for its uniform pure white consistency, lacking, for the most part, the gray streaking commonly found in other marbles. The Yule Marble deposit — named for George Yule, a prospector who rediscovered the stone in 1874 — is among the largest in the world. At 99.5% pure calcite, it is one of the purest marbles ever quarried. It is Colorado's official state rock.
