Lyons Sandstone is a geological layer formed during the Paleozoic Era, Middle Permian Period about 250 million years ago. This layer is also referred to as the Lyons Formation. It is the result of fine-grained quartz sand dunes compressing into sandstone. This layer is visible along the Front Range of the Colorado Rocky Mountains.
The stone quarried from this layer was used to build many buildings on the University of Colorado - Boulder campus.
