Yule Marble is a type of marble derived from the metamorphosed Leadville Limestone, exclusively located in the Yule Creek Valley within the West Elk Mountains of Colorado, approximately 2.8 miles (4.5 km) southeast of the town of Marble, Colorado. It was first identified in 1873 and is extracted from underground quarries situated at an elevation of 9,300 feet (2,800 m) above sea level, which distinguishes it from most marbles that are typically mined from open pits at significantly lower altitudes. The unique geological conditions of the area have resulted in a marble that boasts 99.5% pure calcite, characterized by a grain structure that imparts a smooth texture, a uniform appearance, and a radiant surface.

These exceptional attributes led to its selection for the exterior cladding of the Lincoln Memorial, among various other notable structures across the United States, despite its higher cost compared to alternative marbles. The substantial size of the deposits allows for the extraction of large blocks, which is why Yule Marble was used for the 56-long-ton (57 t) die block of the Tomb of the Unknown Soldier at Arlington National Cemetery. The premium quality of Yule Marble comes with significant expenses due to the challenges associated with quarrying in a high-altitude mountainous region. This difficulty has resulted in numerous cycles of economic prosperity and decline for both the marble industry and the town of Marble since quarrying commenced in the mid-1880s, rendering the town a symbol of the economic volatility typical of single-industry economies. Although advancements in quarrying technology and transportation have alleviated some of the cost issues, they have not entirely resolved the financial challenges that continue to affect operations today.
