Paw Paw Tunnel
The Paw Paw Tunnel is a canal tunnel on the Chesapeake and Ohio Canal (C&O) in Oldtown, Maryland, in Allegany County, Maryland. Located near Paw Paw, West Virginia, it was built to bypass the Paw Paw Bends, a stretch of the Potomac River containing five horseshoe-shaped bends. The town, the bends, and the tunnel take their name from the pawpaw trees that grow prolifically along nearby ridges. Built using more than six million bricks, the tunnel has been described as "the greatest engineering marvel along the Chesapeake & Ohio Canal National Historical Park." Located at milepost 155.2, the tunnel served to eliminate six miles of canal and is credited with contributing to the economic success of nearby Cumberland, Maryland. Construction on the tunnel began in 1836 and was expected to be completed within two years at a total cost of $33,500. But the project proved far more complicated and costly than expected, and the tunnel did not open until 1850, more than a decade behind sched ...

Chesapeake And Ohio Canal National Historical Park
The Chesapeake and Ohio Canal National Historical Park is located in the District of Columbia and the state of Maryland. The park was established in 1961 as a National Monument by President Dwight D. Eisenhower to preserve the neglected remains of the Chesapeake and Ohio Canal and many of its original structures. The canal and towpath trail extends along the Potomac River from the Georgetown section of Washington, D.C., to Cumberland, Maryland, a distance of . In 2013, the path was designated as the first section of U.S. Bicycle Route 50. With over four million visitors in 2022, it is the most-visited unit that is designated a national historical park of the National Park Service. The Chesapeake and Ohio Canal Construction on the Chesapeake and Ohio Canal (also known as "the Grand Old Ditch" or the "C&O Canal") began in 1828 and ended in 1850 when the canal reached Cumberland, far short of its intended destination of Pittsburgh, Pennsylvania. Occasionally there was talk of ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tunnels Completed In 1850
A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is usually completely enclosed except for the two Portal (architecture), portals common at each end, though there may be access and ventilation openings at various points along the length. A Pipeline transport, pipeline differs significantly from a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail transport, rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sanitary sewer, sewers or aqueduct (watercourse), aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passa ...

Historic American Buildings Survey In Maryland
History is the systematic study of the past, focusing primarily on the human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives of several sources to develop a ...

Canal Tunnels In The United States
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a navigation canal when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal. Many cana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rockslide
A rockslide is a type of landslide caused by rock failure in which part of the bedding plane of failure passes through compacted rock and material collapses ''en masse'' and not in individual blocks. Note that a rockslide is similar to an avalanche because they are both slides of debris that can bury a piece of land. While a landslide occurs when loose dirt or sediment falls down a slope, a rockslide occurs only when solid rocks are transported down slope. The rocks tumble downhill, loosening other rocks on their way and smashing everything in their path. Fast-flowing rock slides or debris slides behave similarly to snow avalanches, and are often referred to as rock avalanches or debris avalanches. Definition The term landslide refers to a variety of mass wasting Mass wasting, also known as mass movement, is a general term for the movement of rock (geology), rock or soil down slopes under the force of gravity. It differs from other processes of erosion in that the deb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flag Semaphore
Flag semaphore (from the Ancient Greek () 'sign' and - (-) '-bearer') is a semaphore system conveying information at a distance by means of visual signals with hand-held flags, rods, disks, paddles, or occasionally bare or gloved hands. Information is encoded by the position of the flags; it is read when the flag is in a fixed position. Semaphores were adopted and widely used (with hand-held flags replacing the mechanical arms of semaphore line, shutter semaphores) in the maritime world in the 19th century. It is still used during underway replenishment at sea and is acceptable for emergency communication in daylight or using lighted wands instead of flags, at night. Contemporary semaphore flag system The current flag semaphore system uses two short poles with square flags, which a signal person holds in different positions to signal letters of the alphabet and numbers. The signaller holds one pole in each hand, and extends each arm in one of eight possible directions. Except ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
