Sandstone. Many sandstone deposits have been mined and used for aggregate, road base, and antiskid material, and some sandstones have been used in silica sands. Several quarries are in the eastern and western parts of the state. Many of these quarries operate intermittently, and many abandoned quarries may still have reserves left for future mining.
