W.T. Preston
''W. T. Preston'' is a specialized sternwheeler that operated as a snagboat, removing log jams and natural debris that prevented river navigation on several Puget Sound-area rivers. She is now the centerpiece of the Snagboat Heritage Center in Anacortes, Washington. She was designated a National Historic Landmark in 1989. Built in 1929, she is one of two surviving snagboats built and operated by the United States Army Corps of Engineers, and the only one on the American west coast. History ''W. T. Preston'' operated from Olympia to Blaine, including the Skagit, Stillaguamish, and Snohomish rivers. Dead trees that reached Puget Sound often became half-submerged deadheads that could pierce the hulls of wooden vessels. The federal government began building snagboats to remove obstructions and facilitate river based commerce. ''W. T. Preston'' was named in honor of the only civilian engineer to work for the Army Corps of Engineers at the time of her construction in 1929. ...

Stillaguamish River
The Stillaguamish River is a river in the northwestern region of the U.S. state of Washington. It is mainly composed of two forks, the longer North Fork Stillaguamish () and the South Fork Stillaguamish. The two forks join near Arlington. From there the Stillaguamish River proper flows for to Puget Sound. The river's watershed drains part of the Cascade Range north of Seattle. Course The Stillaguamish River is formed from the confluence of the North and South Forks, both of which rise in the Cascades. Between the North and South forks there is a portion of the Mount Baker-Snoqualmie National Forest called the Boulder River Wilderness. The North Fork rises as several branches in a remote area of Skagit County near Finney Peak, approximately north of Darrington. Collecting many tributary creeks, the river flows south, then west through the foothills along the Skagit- Snohomish county line. Tributaries of the North Fork Stillaguamish River include Boulder River and Deer Cree ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Historic American Engineering Record In Washington (state)
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Dredgers
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Dredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material of value or use, or to create a greater depth of water. Dredges have been classified as suction or mechanical. Dredging has significant environmental impacts: it can disturb marine sediments, leading to both short- and long-term water pollution, destroy important seabed ecosystems, and can release human-sourced toxins captured in the sediment.

Historic Preservation
Historic preservation (US), built heritage preservation or built heritage conservation (UK), is an endeavor that seeks to preserve, conserve and protect buildings, objects, landscapes or other artifacts of historical significance. It is a philosophical concept that became popular in the twentieth century, which maintains that cities as products of centuries’ development should be obligated to protect their patrimonial legacy. The term refers specifically to the preservation of the built environment, and not to preservation of, for example, primeval forests or wilderness. Areas of professional, paid practice Paid work, performed by trained professionals, in historic preservation can be divided into the practice areas of regulatory compliance, architecture and construction, historic sites/museums, advocacy, and downtown revitalization/rejuvenation; each of these areas has a different set of expected skills, knowledge, and abilities. United States In the United States, about 70% o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Montgomery (snagboat)
''Montgomery'' is a steam-powered sternwheel-propelled snagboat built in 1925 by the Charleston Dry Dock and Machine Company of Charleston, South Carolina, and operated by the United States Army Corps of Engineers. ''Montgomery'' cleared snags and obstructions from the Coosa, Alabama, Apalachicola, Chattahoochee, Flint, Black Warrior, and Tombigbee Rivers until her retirement from the Corps of Engineers on November 8, 1982. She was restored in 1984 and again in 2004. One of only two surviving Army Corps of Engineers snagboats (along with '' W.T. Preston''), she was declared a National Historic Landmark in 1989., and ''Montgomery'' now operates as a museum ship at the Tom Bevill Lock and Dam Visitor Center in Pickensville, Alabama. ''Montgomery'' is built out of steel plates mounted in a steel frame. Her hull is long, which extends to with the addition of the sternwheel. She is wide, and has a hold depth of . She has a scow-shaped bow and a flat bottom with no keel. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Smokestack
A chimney is an architectural ventilation structure made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler, stove, furnace, incinerator, or fireplace from human living areas. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney effect. The space inside a chimney is called the ''flue''. Chimneys are adjacent to large industrial refineries, fossil fuel combustion facilities or part of buildings, steam locomotives and ships. In the United States, the term ''smokestack industry'' refers to the environmental impacts of burning fossil fuels by industrial society, including the electric industry during its earliest history. The term ''smokestack'' (colloquially, ''stack'') is also used when referring to locomotive chimneys or ship chimneys, and the term ''funnel'' can also be used. The height of a chim ...

Hull (watercraft)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. ...

Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its masts or any armament turrets. Note that in modern times, turrets do not always carry naval artillery, but they can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure on board a ship or a bo ...
