The E. L Smith Quarry in Graniteville, South Barre, Vermont, USA, has been the source of Barre gray granite since opening in 1883. The quarry was started as a partnership between brothers John E. Smith and Emery L. Smith. Another brother, Donald Smith, joined them in 1887, forming E. L Smith and Company. John and Donald eventually bought out their brother, but kept the name. Currently owned by Rock of Ages, E. L. Smith is the largest open granite quarry in the world. Stone workers cut 50-foot squares 10 feet deep from the intrusive igneous rock formation. They create granite benches by drilling vertical holes four inches apart around the 200-foot perimeter. They also bore under the benches using five-foot sections of extensible drilling rods. To free up the benches for removal, stone workers set explosive charges to beach the spaces between the holes. They next cut each bench into 40-ton blocks to enable removal of the dense rock from the quarry. Granite taken from the quarry weighs 170 pounds for each cubic foot. Quarry and factory tours are available from late Spring through late summer. See the Rock of Ages website for details: http://www.rockofages.com/.
