The Allegheny River is a 325-mile (523 km) long headwater stream of the Ohio River in western Pennsylvania and New York. The Allegheny River runs from its headwaters just below the middle of Pennsylvania's northern border northwesterly into New York then in a zigzag southwesterly across the border and through Western Pennsylvania to join the Monongahela River at the Forks of the Ohio on the "Point" of Point State Park in Downtown Pittsburgh, Pennsylvania. The Allegheny River is, by volume, the main headstream of both the Ohio and Mississippi Rivers. Historically, the Allegheny was considered to be the upper Ohio River by both Native Americans and European settlers.
Somerset County is a county located in the U.S. state of Pennsylvania. As of the 2010 census, the population was 77,742. Its county seat is Somerset. The county was created from part of Bedford County on April 17, 1795, and named after the county of Somerset in England.
In structural geology, an anticline is a type of fold that is an arch-like shape and has its oldest beds at its core, whereas a syncline is the inverse of an anticline. A typical anticline is convex up in which the hinge or crest is the location where the curvature is greatest, and the limbs are the sides of the fold that dip away from the hinge. Anticlines can be recognized and differentiated from antiforms by a sequence of rock layers that become progressively older toward the center of the fold. Therefore, if age relationships between various rock strata are unknown, the term antiform should be used.
The American Institute of Mining, Metallurgical, and Petroleum Engineers (AIME) is a professional association for mining and metallurgy, with over 145,000 members. It was founded in 1871 by 22 mining engineers in Wilkes-Barre, Pennsylvania, United States, being one of the first national engineering societies in the country. Its charter is to "advance and disseminate, through the programs of the Member Societies, knowledge of engineering and the arts and sciences involved in the production and use of minerals, metals, energy sources and materials for the benefit of humankind."
Larrys Creek is a 22.9-mile-long (36.9 km) tributary of the West Branch Susquehanna River in Lycoming County in the U.S. state of Pennsylvania. A part of the Chesapeake Bay drainage basin, its watershed drains 89.1 square miles (231 km2) in six townships and a borough. The creek flows south from the dissected Allegheny Plateau to the Ridge-and-valley Appalachians through sandstone, limestone, and shale from the Devonian, Mississippian, and Pennsylvanian periods.
The Silver Valley is a region in the northwest United States, in the Coeur d'Alene Mountains in northern Idaho. It is noted for its mining heritage, dating back to the 1880s.
The Jersey Shore, Pine Creek and Buffalo Railway was a railroad built in the early 1880s to give the New York Central and Hudson River Railroad access to the coal regions around Clearfield, Pennsylvania, United States. It was originally planned as part of a connecting line between the East Coast of the United States and Buffalo, New York.
Raymond Alexander Price, is a Canadian geologist. He has used his research on the structure and tectonics of North America’s lithosphere to produce extensive geological maps. He has also provided guidance for nuclear fuel waste disposal and reports on the human contribution to Global warming.
Uranium mining in Utah, a state of the United States, has a history going back more than 100 years. Uranium mining started as a byproduct of vanadium mining about 1900, became a byproduct of radium mining about 1910, then back to a byproduct of vanadium when the radium price fell in the 1920s. Utah saw a uranium boom in the late 1940s and early 1950s, but uranium mining declined in the 1980s. Since 2001 there has been a revival of interest in uranium mining, as a result of higher uranium prices.
The Marcellus Formation or the Marcellus Shale is a Middle Devonian age unit of sedimentary rock found in eastern North America. Named for a distinctive outcrop near the village of Marcellus, New York, in the United States, it extends throughout much of the Appalachian Basin.
William Embry Wrather was an American geologist.
The Pittsburgh Coal Seam is the thickest and most extensive coal bed in the Appalachian Basin; hence, it is the most economically important coal bed in the eastern United States. The Upper Pennsylvanian Pittsburgh coal bed of the Monongahela Group is extensive and continuous, extending over 11,000 mi2 through 53 counties. It extends from Allegany County, Maryland to Belmont County, Ohio and from Allegheny County, Pennsylvania southwest to Putnam County, West Virginia.
Savage Mountain is an anticline extending from Bedford County, Pennsylvania southwest into Western Maryland. It is the western side of the Ridge-and-Valley Appalachians, and the eastern portion of the ridge forms the border of Garrett and Allegany Counties of Maryland.
The Tri-State district was a historic lead-zinc mining district located in present-day southwest Missouri, southeast Kansas and northeast Oklahoma. The district produced lead and zinc for over 100 years. Production began in the 1850s and 1860s in the Joplin - Granby area of Jasper and Newton counties of southwest Missouri. Production was particularly high during the World War I era and continued after World War II, but with declining activity. As jobs left the area, the communities declined in population.
The East Tintic Mountains are a mountain range in central Juab, Utah, and Tooele counties in Utah, United States on the east margin of the Great Basin just west of the Wasatch Front about 50 miles (80 km) south-southeast of Salt Lake City. The community of Eureka is an old mining town near the center of the range. U.S. Route 6 Passes through the central part of the range and through Eureka.
James Putnam Kimball was a United States metallurgist and geologist who was Director of the United States Mint from 1885 to 1889.
Eckley Brinton Coxe was an American mining engineer, coal baron, state senator and philanthropist from Pennsylvania. He was a co-founder of the Coxe Brothers and Company coal mining operation which became the largest individual producer of anthracite coal in the United States at the time.
James Gayley was an American chemist and steel metallurgist who served as managing director of the Carnegie Steel Company, and as the first vice president of U.S. Steel from 1901 to 1908. He is credited with many inventions which greatly improved the fields of steel and iron making. For his contributions in the field of metallurgy, he was awarded the Elliott Cresson Medal in 1909, and the Perkin Medal in 1913.
John Robert Suman was a geologist, petroleum engineer, and business executive.
