Prince William County
Prince William County is located on the Potomac River in the U.S. state of Virginia. As of the 2020 census, the population sits at 482,204, making it Virginia's second-most populous county. Its county seat is the independent city of Manassas. A part of Northern Virginia, Prince William County is part of the Washington metropolitan area. In 2019 it had the 20th-highest income of any county in the United States. History At the time of European colonization, the native tribes of the area that would become Prince William County were the Doeg, an Algonquian-speaking sub-group of the Powhatan tribal confederation. When John Smith and other English explorers ventured to the upper Potomac River beginning in 1608, they recorded the name of a village the Doeg inhabited as ''Pemacocack'' (meaning "plenty of fish" in their language). It was located on the west bank of the Potomac River about 30 miles south of present-day Alexandria. Unable to deal with European diseases and firepow ...

Neabsco Creek
Neabsco Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 15, 2011 tributary of the lower tidal segment of the Potomac River in eastern Prince William County, Virginia. The Neabsco Creek watershed covers about . The name Neabsco is derived from a Doeg village recorded as ''Niopsco'' by early English colonists. The creek has served as a vital waterway for trade and commerce in northern Virginia since the eighteenth century. The Neabsco's watershed is highly developed because of its proximity to the I-95 corridor and the Washington, D.C. metropolitan area. The EPA Office of Water recently identified the Neabsco Creek watershed as an "area of significant habitat degradation due to a loss of natural land cover and storm water management facilities designed without consideration for environmental conditions." Most of Dale City and Woodbridge empty into Neabsco Creek. Prince William County has made significan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interstate 95 In Virginia
Interstate 95 (I-95) runs within the Commonwealth of Virginia between its borders with North Carolina and Maryland. I-95 meets the northern terminus of I-85 in Petersburg, and is concurrent with I-64 for in Richmond. Although I-95 was originally planned as a highway through Washington, D.C. (following the route of what is now I-395), it was rerouted along the eastern portion of the Capital Beltway. From Petersburg to Richmond, I-95 utilized most of the Richmond–Petersburg Turnpike, a former toll road (the south end of the toll road was on I-85). It enters the Capital Beltway at the Springfield Interchange, also known as the Mixing Bowl. I-95 continues over the Woodrow Wilson Bridge into Washington, D.C. (for 0.11 miles on the bridge), and then into Maryland on the Capital Beltway. The route between Fredericksburg and Springfield is consistently one of the most congested routes of highway in the United States, particularly during holidays and rush hours. The causes for ...

Quantico Creek
Quantico Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 15, 2011 partially tidal tributary of the Potomac River in eastern Prince William County, Virginia. Quantico Creek rises southeast of Independent Hill, flows through Prince William Forest Park and Dumfries and empties into the Potomac at Possum Point. History John Smith in 1608 reported the existence of a Doeg community called ''Pamacocack'' on the banks of this creek, as well as on the directly opposite (Maryland) side of the Potomac. This is thought to be a likely candidate for the place Henry Spelman was found living among the natives, which he reported was named "Nacottawtanke, but by our english cald icCamocacocke". Early land patents spell the name of the creek variously as ''Quancico'' (1654), ''Quanticotte'' (1654, 1658), ''Quantecot'' (1657), ''Quanticoke'' (1664), ''Quonticutt'' (1665), and ''Quanticutt'' (1665).Nugent, ''Cavalier ...

Stamp Mill
A stamp mill (or stamp battery or stamping mill) is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation. Description A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft. As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam. Each one frame and stamp set is sometimes called a "battery" or, confusingly, a "stamp" and mills are sometimes categorised by how many stamps they have, i.e. a "10 stamp mill" has 10 sets. They usually are arranged linearly, but when a mill is enlarged, a new line of them may be constructed rather than extending the line. Abandoned mill sites (as ...

Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in ...

These alloys are formed through metallic bonding, with the electrostatic attractive force of the conduction electrons working to bind all the positively charged metal ions together into a Crystal structure, crystal lattice structure. Almost all metals can form amalgams with mercury, the notable exceptions being iron, platinum, tungsten, and tantalum. Silver-mercury amalgam (dentistry), amalgams are important in dentistry, and gold-mercury amalgam is used in the Gold extraction, extraction of gold from ore. Dentistry has used alloys of mercury with metals such as silver, copper, indium, tin a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Park Service
The National Park Service (NPS) is an agency of the United States federal government within the U.S. Department of the Interior that manages all national parks, most national monuments, and other natural, historical, and recreational properties with various title designations.

Virginia Gold Mining
Most gold mining in Virginia was concentrated in the Virginia Gold-Pyrite belt in a line that runs northeast to southwest through the counties of Fairfax, Prince William, Stafford, Fauquier, Culpeper, Spotsylvania, Orange, Louisa, Fluvanna, Goochland, Cumberland, and Buckingham. Some gold was also mined in Halifax, Floyd, and Patrick counties. History of Virginia gold mining The earliest recording of gold mining activity in Virginia began about 1804 as placer mining, followed quickly by lode mining. Mining continued unabated until the onset of the California Gold Rush, at which point most serious speculators moved west. Production continued at a low level until the Civil War, when it virtually ground to a halt. Near the end of the war, Union troops began a systematic campaign to destroy the economic base of the South. Many gold mines were subsequently damaged beyond repair. Most were, by this time, marginal producers, their ores of such low concentrate as to stretch t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
