Cascade Falls (Ellicott City)
Patapsco Valley State Park is a Maryland state park extending along of the Patapsco River south and west of the city of Baltimore, Maryland. The park encompasses multiple developed areas on over acres of land, making it Maryland's largest state park. In 2006, it was officially celebrated as Maryland's first state park, its first formation being in 1906. Patapsco Valley State Park is managed by the Maryland Department of Natural Resources. History ;20th century Formation of the park started with provisions in the Forestry Act of 1906. The completion of Bloede's Dam in 1906 required the implementation of protections to prevent silting from nearby farm erosion. Patapsco Valley State Park was established as Patapsco State Forest Reserve in 1907 to protect the valley's forest and water resources. The first 43 acres were donated by Russell Sage Foundation director John Mark Glenn (1858-1950) from his Hilton estate. Glenn's Hilton became the namesake for the park's Hilton Area. In 191 ...

Thomas Viaduct
The Thomas Viaduct spans the Patapsco River and Patapsco Valley between Relay, Maryland and Elkridge, Maryland, USA. It was commissioned by the Baltimore and Ohio Railroad (B&O); built between July 4, 1833, and July 4, 1835; and named for Philip E. Thomas, the company's first president. It remains the world's oldest multiple arched stone railroad bridge. At its completion, the Thomas Viaduct was the largest railroad bridge in the United States and the country's first multi-span masonry railroad bridge to be built on a curve. In 1964, it was designated as a National Historic Landmark. In 2010, the bridge was designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers. The viaduct is now owned and operated by CSX Transportation and still in use today, making it one of the oldest railroad bridges still in service. Design This Roman-arch stone bridge is divided into eight spans. It was designed by Benjamin Henry Latrobe, II, then B&O' ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railroad
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storey
A storey (British English) or story (American English) is any level part of a building with a floor that could be used by people (for living, work, storage, recreation, etc.). Plurals for the word are ''storeys'' (UK) and ''stories'' (US). The terms ''floor'', ''level'', or ''deck'' are used in similar ways, except that it is usual to speak of a "16-''storey'' building", but "the 16th ''floor''". The floor at ground or street level is called the "ground floor" (i.e. it needs no number; the floor below it is called "basement", and the floor above it is called "first") in many regions. However, in some regions, like the U.S., ''ground floor'' is synonymous with ''first floor'', leading to differing numberings of floors, depending on region – even between different national varieties of English. The words ''storey'' and ''floor'' normally exclude levels of the building that are not covered by a roof, such as the terrace on the rooftops of many buildings. Nevertheless, a flat r ...

Suspension Bridge
A suspension bridge is a type of bridge in which the deck (bridge), deck is hung below suspension wire rope, cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the Structural load#Live load, imposed loads, transient load, live and Structural load#Dead load, dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange Grove Flour Mill
The Orange Grove Flour Mill was a flour mill established in 1856. It was one of the leading flour mills in the Mid-Atlantic states until it was destroyed in a fire in 1905. History The Mill was established in 1856 by a partnership of Dailey and Worthington. It was originally one of many flour mills and other industries built along the river near Ellicott City. In 1860, the mill with a production of 500 barrels a day was sold to Charles A. Gambrill Esq. It was one of the only structures not badly damaged by a flood on 24 July 1868, and was back online in mid August. It quickly became the leading flour manufacturer in the area, though the flood did also lead to a general period of decline in the area, a former Mid-Atlantic leader in manufacturing. For a time, Orange Grove Flour Mill was the largest flour mill east of Minneapolis. While the five story mill was owned by the C.A. Gambrill Manufacturing Company, it produced a peak between 1,200 and 1,500 barrels of flour daily. In 1905, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catonsville, Maryland
Catonsville is a census-designated place (CDP) in Baltimore County, Maryland, United States. The population was 41,567 at the 2010 census. The community lies to the west of Baltimore along the city's border. Catonsville contains the majority of the University of Maryland, Baltimore County (UMBC), a major public research university with close to 14,000 students. History Before European colonists settled in present-day Catonsville, the area was occupied by the Piscataway tribe or the Susquehannocks. Rolling Road was used to transport tobacco south from plantations to the Patapsco River on horse-drawn wagons. In 1787, the Ellicott family built the Frederick Turnpike to transport goods from their flour mill, Ellicott Mills, to the Baltimore harbor. Charles Carroll, the last surviving signer of the Declaration of Independence at the time, owned the land around the then newly built road. He instructed his son-in-law, Richard Caton, to develop the area along the road. Caton and his wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grist Mill Trail Tunnel
Grist is grain that has been separated from its chaff in preparation for grinding. It can also mean grain that has been ground at a gristmill. Its etymology derives from the verb ''grind.'' Grist can be ground into meal or flour, depending on how coarsely it is ground. Maize made into grist is called grits when it is coarse, and corn meal when it is finely ground. Wheat, oats, barley, and buckwheat are also ground and sifted into flour and farina. Grist is also used in brewing and distillation to make a mash. "Grist for the mill" The proverb "all is grist for the mill" means "everything can be made useful, or be a source of profit." There are some minor variations, such as "all's grist that comes to his mill", meaning that the person in question can make something positive out of anything that comes along. A miller ground whatever grain was brought to him, and charged a portion of the final product for the service. Therefore, all grain arriving at the mill represented incom ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Patapsco Camp, Civilian Public Service
The Patapsco Camp or the CPS Camp No. 3 was a Civilian Public Service camp established during World War II for conscientious objectors. Located at the Patapsco Valley State Park near Baltimore, the site was the first Civilian Public Service camp for conscientious objectors in the United States. History The camp was opened on May 15, 1941, and closed in September 1942. The camp was a National Park Service base camp located on a former Civilian Conservation Corps (CCC) camp near Elkridge, Maryland, in the Patapsco Valley State Park, then known as the Patapsco State Forest. The CCC camp was known as Camp Tydings, as New Deal project operating between 1933 and 1942. The camp allowed drafted conscientious objectors, predominantly Christian pacifists, to serve the country without fighting in the war. The men serving in the camp faced public hostility. One conscientious objector received a letter calling conscientious objectors "Hitler's little helpers". The camp was 2 to 3 acres in siz ...

Conscientious Objector
A conscientious objector (often shortened to conchie) is an "individual who has claimed the right to refuse to perform military service" on the grounds of freedom of thought, conscience, or religion. The term has also been extended to objecting to working for the military–industrial complex due to a crisis of conscience. In some countries, conscientious objectors are assigned to an alternative civilian service as a substitute for conscription or military service. A number of organizations around the world celebrate the principle on May 15 as International Conscientious Objection Day. On March 8, 1995, the United Nations Commission on Human Rights resolution 1995/83 stated that "persons performing military service should not be excluded from the right to have conscientious objections to military service". This was re-affirmed on April 22, 1998, when resolution 1998/77 recognized that "persons lreadyperforming military service may ''develop'' conscientious objections". H ...
