Colorado's State Symbols: The State Rock

Not to be confused with the State Gemstone (Aquamarine) and the State Mineral (Rhodochrosite), the State Rock is Colorado Yule Marble.  Quarried in Marble, Colorado in Gunnison County, Colorado Yule Marble has been used in many important buildings around the state including the Colorado State Capitol; it has also been used in the Washington Monument, Lincoln Memorial, and Tomb of the Unknown Soldier in Washington, D.C.  Colorado Yule Marble was designated the State Rock in 2004 on petition from a girl scout troop from Lakewood.  For more information on Colorado Yule Marble, see Engineering Geologic Factors of the Marble Area, Gunnison County, Colorado, available from our library.
