Danville And Pottsville Railroad
This is a list of the earliest railroads in North America, including various railroad-like precursors to the general modern form of a company or government agency operating locomotive-drawn trains on metal tracks. Railroad-like entities (1700s–1810s) *1720: A railroad was reportedly used in the construction of the French fortress at Louisburg, Nova Scotia, Canada. *1764: Between 1762 and 1764, at the close of the French and Indian War, a gravity railroad ( mechanized tramway) ( Montresor's Tramway) was built by British military engineers up the steep riverside terrain near the Niagara River waterfall's escarpment at the Niagara Portage (which the local Senecas called ''"Crawl on All Fours."'') in Lewiston, New York. and Jim Thorpe, Pennsylvania, Mauch Chunk (now Jim Thorpe), Pennsylvania when rails are laid on top of the existing mule-haul road graded to be nearly uniform in grade from its establishment in 1819-20.

Summit Hill Switchback Station
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary. ...

John Montresor
Captain John Montresor (22 April 1736 – June 1799) was a British military engineer and cartographer in North America. Early life Born in Gibraltar 22 April 1736 to British military engineer James Gabriel Montresor and his first wife, Mary Haswell, John Montresor spent his early life there (and presumably on Menorca, where his father was briefly stationed). He was in England between 1746 and 1750, attending Westminster School. He learned the principles of engineering from his father, and in his later teens served as assistant engineer to his father at Gibraltar. French and Indian Wars In 1754, he accompanied his father to America, and served as an ensign in the 48th Regiment of Foot on the expedition to Fort Duquesne, also performing as a supernumerary engineer. In the defeat that followed he was wounded, but survived to learn of his promotion to lieutenant days before the battle.

Mount Vernon Proprietors
Mount Vernon Proprietors was a real estate development syndicate operating in Boston, Massachusetts. Founded at the end of the 18th century, it developed land on the south slope of Beacon Hill into a desirable residential neighborhood. History In 1795 a syndicate formed by Harrison Gray Otis sought to speculate on land development around the newly formed government buildings on Boston's Beacon Hill. The Mount Vernon Proprietors, as the group was named, included founders Otis, Jonathan Mason, Joseph Woodward and Charles Ward Apthorp. Membership in the Proprietors changed frequently but partners included Charles Bulfinch, Hepzibah Swan, Henry Jackson, Dr. Benjamin Joy, William Scollay.Allan Chamberlain.

Back Bay, Boston
Back Bay is an officially recognized neighborhood of Boston, Massachusetts, built on reclaimed land in the Charles River basin. Construction began in 1859, as the demand for luxury housing exceeded the availability in the city at the time, and the area was fully built by around 1900. It is most famous for its rows of Victorian brownstone homes—considered one of the best preserved examples of 19th-century urban design in the United States—as well as numerous architecturally significant individual buildings, and cultural institutions such as the Boston Public Library, and Boston Architectural College. Initially conceived as a residential-only area, commercial buildings were permitted from around 1890, and Back Bay now features many office buildings, including the John Hancock Tower, Boston's tallest skyscraper. It is also considered a fashionable shopping destination (especially Newbury and Boylston Streets, and the adjacent Prudential Center and Copley Place malls) and home to ...

Charles River
The Charles River ( Massachusett: ''Quinobequin)'' (sometimes called the River Charles or simply the Charles) is an river in eastern Massachusetts. It flows northeast from Hopkinton to Boston along a highly meandering route, that doubles back on itself several times and travels through 23 cities and towns before reaching the Atlantic Ocean. The indigenous Massachusett named it ''Quinobequin'', meaning "meandering". Hydrography The Charles River is fed by approximately 80 streams and several major aquifers as it flows , starting at Teresa Road just north of Echo Lake () in Hopkinton, passing through 23 cities and towns in eastern Massachusetts before emptying into Boston Harbor Boston Harbor is a natural harbor and estuary of Massachusetts Bay, and is located adjacent to the city of Boston, Massachusetts.

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Foundation (engineering)
In engineering, a foundation is the element of a structure which connects it to the ground, transferring loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics (geotechnical engineering) in the design of foundation elements of structures. Purpose Foundations provide the structure's stability from the ground: * To distribute the weight of the structure over a large area in order to avoid overloading the underlying soil (possibly causing unequal settlement). * To anchor the structure against natural forces including earthquakes, floods, droughts, frost heaves, tornadoes and wind. * To provide a level surface for construction. * To anchor the structure deeply into the ground, increasing its stability and preventing overloading. * To prevent lateral movements of the supported structure (in some cases). Requirements of a good foundation The design and the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Bulfinch
Charles Bulfinch (August 8, 1763 – April 15, 1844) was an early American architect, and has been regarded by many as the first American-born professional architect to practice.Baltzell, Edward Digby. ''Puritan Boston & Quaker Philadelphia''. Transaction Publishers (1996), p. 322-24. . Life Bulfinch split his career between his native Boston, Massachusetts, and Washington, D.C., where he served as Commissioner of Public Building and built the intermediate United States Capitol rotunda and dome. His works are notable for their simplicity, balance, and good taste, and as the origin of a distinctive Federal style of classical domes, columns, and ornament that dominated early 19th-century American architecture. Early life Bulfinch was born in Boston to Thomas Bulfinch, a prominent physician, and his wife, Susan Apthorp, daughter of Charles Apthorp. At the age of 12, he watched the Battle of Bunker Hill from this home on the Boston side of the Charles River. He was educated at Bo ...
