Anthracite iron or anthracite pig iron is iron extracted by the smelting together of anthracite coal and iron ore, that is using anthracite coal instead of charcoal in iron smelting. This was an important technical advance in the late-1830s, enabling a great acceleration of the Industrial Revolution in the United States and in Europe.
Livermore, Pennsylvania is an abandoned town that was located on the Conemaugh River between Blairsville and Saltsburg in Derry Township, Westmoreland County, Pennsylvania. The town was abandoned and partially razed in the early 1950s following authorization by the Flood Control Act of 1936 and Flood Control Act of 1938 for construction of the Conemaugh Dam and Lake to prevent flooding of Pittsburgh. Much of the former town site now lies under the reservoir and floodplains.
The Schuylkill Canal, or Schuylkill Navigation, was a system of interconnected canals and slack-water pools along the Schuylkill River in the U.S. state of Pennsylvania, built as a commercial waterway in the early 19th-century. Chartered in 1815, the navigation opened in 1825, to provide transportation and water power.
The Lehigh Crane Iron Company, later renamed Crane Iron Company, was a major ironmaking firm in the Lehigh Valley from its founding in 1839 until its sale in 1899. It was based in Catasauqua, Pennsylvania, and was founded by Josiah White and Erskine Hazard, who financed its development through their Lehigh Coal & Navigation Company, which promoted the then-novel technique of smelting iron ore with anthracite coal. This was an important cost and energy savings technique, credited with eliminating the need for either expensive charcoal or coke producing processes and transport costs that proved central to the acceleration of the American Industrial Revolution.
Rock Creek is an 18.9-mile-long (30.4 km) tributary of the Monocacy River in south-central Pennsylvania and serves as the border between Cumberland and Mount Joy townships. Rock Creek was used by the Underground Railroad and flows near several Gettysburg Battlefield sites, including Culp's Hill, the Benner Hill artillery location, and Barlow Knoll.
The Genesee Valley Greenway is a rail trail in western New York's Genesee River valley.
The Susquehanna and Tidewater Canal between Wrightsville, Pennsylvania, and Havre de Grace, Maryland, at the head of Chesapeake Bay, provided an interstate shipping alternative to 19th-century arks, rafts, and boats plying the difficult waters of the lower Susquehanna River. Built between 1836 and 1840, it ran 43 miles (69 km) along the west bank of the river and rendered obsolete an older, shorter canal along the east bank. Of its total length, 30 miles (48 km) were in Pennsylvania and 13 miles (21 km) in Maryland. Although rivalry between Philadelphia, Pennsylvania, and Baltimore, Maryland, delayed its construction, the finished canal brought increased shipments of coal and other raw materials to both cities from Pennsylvania's interior. Competition from railroads was a large factor in the canal's decline after 1855. Canal remnants, including a lock keeper's house, have been preserved in Maryland, and locks 12 and 15 have been preserved in Pennsylvania.
West Penn Railways, one part of the West Penn System, was an interurban electric railway headquartered in Connellsville, Pennsylvania. It was part of the region's power generation utility.
The Pond Eddy Bridge is a truss bridge spanning the Delaware River between the hamlet of Pond Eddy in Lumberland, New York and the settlement informally called Pond Eddy in Shohola Township, Pennsylvania; it is the Pennsylvania community's only road connection. It is accessible from NY 97 in Lumberland on the New York side and two dead-end local roads, Flagstone Road and Rosa Road on the Pennsylvania side. The current bridge was built in 2018, replacing one from 1903.
Tinkers Creek Aqueduct is an aqueduct that was constructed to bridge the Ohio and Erie Canal over Tinkers Creek near its confluence with the Cuyahoga River in Valley View, Ohio. It is a relatively rare surviving example of an Ohio and Erie Canal aqueduct. It was originally constructed in 1825-1827 by, and re-built due to flood damage in 1845 and 1905. Tinkers Creek Aqueduct was included in a National Historic Landmark district established in 1966, and it was separately listed on the National Register of Historic Places in 1979. The original Tinkers Creek Aqueduct was a wood plank, steel truss, and Ashlar-sandstone structure constructed in 1827, south of the present aqueduct's location. Cuyahoga River and Tinkers Creek flooding caused continual damage to the original aqueduct, so successive structures were built in 1845 and 1905 in the present location. Today, Tinkers Creek Aqueduct is the only aqueduct which remains of the four original aqueducts in the Cuyahoga Valley. Of Furnace Run Aqueduct, Mill Creek Aqueduct, Peninsula Aqueduct, and Aqueduct; Mill Creek Aqueduct, of newer construction, is the only aqueduct which still carries Ohio and Erie Canal water. After 102 years of flooding, weathering, and deterioration, Tinkers Creek Aqueduct was removed in 2007. The National Park Service is currently working on Phase II of the project to reconstruct it from newer materials.
The Barryville–Shohola Bridge is the fifth generation of bridges constructed over the Delaware River at the communities of Shohola Township, Pennsylvania and Barryville, New York. The bridge serves both communities, with two major state legislative highways, Pennsylvania Traffic Route 434 and New York State Touring Route 55. The bridge itself is 812 feet (247 m) long and is 23 feet (7.0 m) wide, using four total spans across the river. It is maintained by the NY–PA Joint Interstate Bridge Commission, which is jointly owned by the states of New York and Pennsylvania.
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.
Derwenthaugh Coke Works was a coking plant on the River Derwent near Swalwell in Gateshead. The works were built in 1928 on the site of the Crowley's Iron Works, which had at one time been the largest iron works in Europe. The coke works was closed and demolished in the late 1980s, and replaced by Derwenthaugh Park.
The Tapeworm Railroad was a railway line planned by Congressman Thaddeus Stevens and nicknamed by opponents ridiculing a lengthy serpentine section around the Green Ridge of South Mountain after an orator compared the path to a tapeworm depiction on a product's packaging. Switchbacks were planned on the west slope at Hughs Forge along the E Br Antietam Creek and on the east slope at Stevens' 1822 Maria Furnace along Toms Creek, with three east slope tunnels through spurs of Jacks Mountain.
Isabella Furnace was a collection of blast furnaces built in 1872 in Etna, Pennsylvania, across the Allegheny River from Pittsburgh.
