The sandstone for the Capitol restoration efforts was mined at a quarry near Rawlins, Wyoming. The majority of the original stone used the Capitol was mined at this quarry in the late 1880s. Special thanks goes to the current quarry owner the Anschutz Corporation which has allowed the State of Wyoming to harvest the stone for free.

Sandstone is a rock comprising mostly of minerals formed from sand. The stone gains its formation throughout centuries of deposits forming in lakes, rivers, or on the ocean floor. These elements group together with the minerals quartz or calcite and compresses. In time, the sandstone is formed by the pressure of these minerals coming together.

Sandstone Formation Formation of the sandstones are cemented grains that may either be fragments of a pre-existing rock or be mono-minerallic crystals. The cements binding these grains together are typically calcite, clays, and silica. Grain sizes in sands are defined (in geology) within the range of 0.0625 mm to 2 mm (0.0025-0.08 inches).
