Deepest wells drilled in the state:
- Calhoun 2503 at 20,222', drilled in 1974 by Exxon USA
- Mingo 805 at 19,600', drilled in 1973 by Columbia Gas Transmission

- Number of counties with oil and gas wells: Wells have been drilled in 53 of the State's 55 counties. At this time, the only two counties with no oil or gas wells are Berkeley and Jefferson counties in the eastern panhandle.
State Rock: Bituminous Coal: The State rock (so designated by a House Concurrent Resolution, 37 in 2009) is bituminous coal. Coal is found naturally deposited in the vast majority of the 55 counties of West Virginia. Coal was discovered in what is now West Virginia in 1742, by European explorer John Peter Salley in the area of Racine, West Virginia. Salley named the nearby tributary of the Kanawha River, where he observed the coal deposit, Coal River. In 1770, George Washington noted "a coal hill on fire" near West Columbia in what is currently Mason County. The first commercial coal mine was opened near Wheeling by Conrad Cotts in 1810, for blacksmithing and domestic use. The coal industry has been an integral part of the economic and social fabric of West Virginia.

State Gem: SilicifiedLithostrotionella, so designated by House Concurrent Resolution No. 39 adopted on March 10, 1990, is technically not a gemstone but the fossilized Late Mississippian coralLithostrotionella, preserved by the siliceous mineral chalcedony. It is found in the Hillsdale Limestone of the Greenbrier Group in portions of Greenbrier and Pocahontas counties in West Virginia and is often cut and polished for jewelry or display.
Lithostrotionella and related corals lived about 340 million years ago during the Mississippian Period at a time when what is now West Virginia was covered by a shallow sea. In addition to corals, the Late Mississippian seas hosted a teeming fauna of brachiopods, trilobites, pelmatozoans, bryozoans, molluscs, and fish. There were two major types of Late Paleozoic corals: tabulate, such asLithostrotionella and rugose. Both types were decimated in the great extinction at the end of the Permian Period, 245 million years ago, when an estimated 95% of the known species of life on earth vanished in a geologic instant. The resultant empty ecological niches were subsequently replaced by the scleractinian corals which form our reefs today.
Corals are generally colonial animals that excrete calcium carbonate (calcite) exoskeletons and frequently merge to form large colonies. Each individual animal, called a polyp, lives in its own small cup or recess. While adult polyps are sessile and live a stationary life, coral larvae are planktonic and are moved around by ocean currents. Polyps strain small particles of food from the water with their tentacles and retreat into the safety of the exoskeleton when threatened. Additionally, polyps host symbiotic algae called zooxanthellae within their tissues. These algae are nourished by the coral's waste products and in turn provide oxygen to the polyp via photosynthesis.
After theLithostrotionella colony died, it became saturated with silica-rich water and the calcium carbonate in the exoskeleton was gradually replaced by the mineral chalcedony, a variety of microcrystalline quartz. West Virginia fossil corals are found in several colors, including light to dark bluish gray, pink, and red. Usually white to bluish gray in color, the unusual pink and red chalcedony in West Virginia'sLithostrotionella comes from trace concentrations of metals such as iron or manganese. Modern living corals get their variety of colors from zooxanthellae algae.
Note: Sando (1983) suggested the type species ofLithostrotionella is most likely a species ofAcrocyathus and assigned the nameAcrocyathus floriformis hemisphaericus to West Virginia specimens. For the state "gemstone," West Virginia still uses the nameLithostrotionella.

- State Fossil:Megalonyx jeffersonii: The State fossil (so designated by House Concurrent Resolution, 28 in 2008) is the extinct Pleistocene ground slothMegalonyx jeffersonii. A left arm and hand were found in a Monroe County cave in the 1790's and scientifically described by Thomas Jefferson in 1797. The new species was named in honor of Jefferson by Caspar Wistar. One of the bones was Carbon-14 dated at 35,960 years.

- State Soil: Monongahela Silt Loam: The State soil (so designated by House Concurrent Resolution, 10 in 1997) is the Monongahela Silt Loam. Monongahela soils cover more than 100,000 acres in 45 counties in West Virginia. These soils are very deep, moderately well drained and occur on alluvial stream terraces that do not flood. Monongahela soils are used extensively for cultivation of crops, pasture, woodlands, hay, and home/building site development. Considered prime farmland, Monongahela soils generally have slopes of 3 percent or less. Find out more about the Monongahela Silt Loam from theWest Virginia Association of Professional Soil Scientists. Recent West Virginia soil surveys are on the United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS)West Virginia Soil Surveys page, and the older booklet-style soil surveys are on thearchived soils surveys page.
