Beaverkill Bridge
Beaverkill Bridge, also known as Conklin Bridge, is a wooden covered bridge over the Beaver Kill north of the hamlet of Roscoe in the Town of Rockland, New York, United States, that carries Conklin Road through Beaverkill State Campground. It was erected in 1865, one of the first bridges over the river in what was then still a largely unsettled region of the Catskill Mountains. It uses an unusual modification of the lattice truss design perfected earlier in the 19th century by Ithiel Town. There is some dispute over which of three men claimed as its builder actually did; it is likely that all of them had some role. It is one of the 29 historic covered bridges in New York State. After undergoing some repairs over the course of the late 20th century, in 2007 it was listed on the National Register of Historic Places, the northernmost property listed in Sullivan County and the only one of four covered bridges in it to be listed. Repair and maintenance efforts continue. Structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beaver Kill
The Beaver Kill, sometimes written as the Beaverkill or Beaverkill River, is a tributary of the East Branch Delaware River, a main tributary of the Delaware River, approximately long, in the U.S. state of New York (state), New York. The Kill (body of water), kill drains a Baldigo, Barry; ; United States Geological Survey; 1999, p. 7. area of the Catskill Mountains and has long been celebrated as one of the most famous trout streams in the United States. Its preservation helped establish many of the basic conservation principles of rivers in the United States. The river has been popular as a trout stream since the early 19th century, when it became one of the first resort destinations in the United States. The subsequent depletion of the brook trout population by the 1850s led to an early conservation movement to preserve the river, including the introduction of hatcheries for brown trout. Its popularity as a trout stream arises in part from the many cold springs and deep pools in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catskill Park
The Catskill Park is in the Catskill Mountains in New York in the United States. It consists of of land inside a Blue Line in four counties: Delaware, Greene, Sullivan, and Ulster. As of 2005, or 41 percent of the land within, is owned by the state as part of the Forest Preserve; it is managed by the Department of Environmental Conservation (DEC). Another 5% is owned by New York City to protect four of the city's reservoirs in the region that lie partially within the park and their respective watersheds. There are bobcats, minks and fishers in the preserve, and coyotes are often heard. There are some 400 black bears living in the region. The state operates numerous campgrounds and there are over of multi-use trails. Hunting is permitted, in season, in much of the park. It has approximately 50,000 permanent residents, bolstered somewhat by second-home ownership on weekends and in the summer, and attracts about half a million visitors every year. The park is governed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Confluence
In geography, a confluence (also: ''conflux'') occurs where two or more flowing bodies of water join to form a single channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); or where two streams meet to become the source of a river of a new name (such as the confluence of the Monongahela and Allegheny rivers at Pittsburgh, forming the Ohio); or where two separated channels of a river (forming a river island) rejoin at the downstream end. Scientific study of confluences Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models. Confluences are relevant to the distribution of living organisms (i.e., ecology) as well; "the general pattern ownstream of confluencesof increasing stream flow and decreasing s ...

Animal Trapping
Animal trapping, or simply trapping or gin, is the use of a device to remotely catch an animal. Animals may be trapped for a variety of purposes, including food, the fur trade, hunting, pest control, and wildlife management. History Neolithic hunters, including the members of the Cucuteni-Trypillian culture of Romania and Ukraine (c. 5500–2750 BCE), used traps to capture their prey. An early mention in written form is a passage from the self-titled book by Taoist philosopher Zhuangzi describes Chinese methods used for trapping animals during the 4th century BCE. The Zhuangzi reads, "The sleek-furred fox and the elegantly spotted leopard ... can't seem to escape the disaster of nets and traps." "Modern" steel jaw-traps were first described in western sources as early as the late 16th century. The first mention comes from Leonard Mascall's book on animal trapping. It reads, "a griping trappe made all of yrne, the lowest barre, and the ring or hoope with two clickets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardenburgh Patent
Major Johannes Hardenbergh (1670–1745), also known as Sir Johannes Hardenbergh, was the owner of the Hardenbergh patent of land in the Catskill Mountains. Biography He was born in Albany, New York, in 1670. He was Sheriff of Ulster County, New York in 1709. He served as a Major in the Ulster County Regiment. In 1706, Hardenbergh bought the immense tract of land since known as the "Hardenbergh patent", which covered some of the Catskill Mountains in what is today Sullivan, Ulster and Delaware counties, from Nanisinos, ''sachem'' of the Esopus Indians, for the sum of 60 pounds.The Catskills: From Wilderness to Woodstock, 1972 by Alf Evers The purchase was subsequently confirmed and patent was granted to Hardenbergh and six others in 1708. There were some disputes as to whether Hardenbergh's acquisition of the property had been truly legal. Indeed, in 1769 another former British officer, John Bradstreet, filed a claim to based on that very assumption. Shares in the patent ...

Buttress
A buttress is an architectural structure built against or projecting from a wall which serves to support or reinforce the wall. Buttresses are fairly common on more ancient buildings, as a means of providing support to act against the lateral (sideways) forces arising out of inadequately braced roof structures. The term ''counterfort'' can be synonymous with buttress and is often used when referring to dams, retaining walls and other structures holding back earth. Early examples of buttresses are found on the Eanna Temple (ancient Uruk), dating to as early as the 4th millennium BC. Terminology In addition to flying and ordinary buttresses, brick and masonry buttresses that support wall corners can be classified according to their ground plan. A clasping or clamped buttress has an L shaped ground plan surrounding the corner, an angled buttress has two buttresses meeting at the corner, a setback buttress is similar to an angled buttress but the buttresses are set back from the ...

Treenail
A treenail, also trenail, trennel, or trunnel, is a wooden peg, pin, or dowel used to fasten pieces of wood together, especially in timber frames, covered bridges, wooden shipbuilding and boat building. It is driven into a hole bored through two (or more) pieces of structural wood (mortise and tenon). History and general use The use of wood as a tenon can be traced back over 7,000 years, as archaeologist have found traces of wood nails in the excavation of early Germanic sites. Trenails are extremely economical and readily available, making them a common early building material. Black Locust is a favorite wood when making trunnels in shipbuilding in North America and English Oak in Europe due to their strength and rot resistance, while red oak is typical in buildings. Traditionally treenails and pegs were made by splitting bolts of wood with a froe and shaping them with a drawknife on a shaving horse. Treenails are cut from a single piece of wood and perform well because of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gable
A gable is the generally triangular portion of a wall between the edges of intersecting roof pitches. The shape of the gable and how it is detailed depends on the structural system used, which reflects climate, material availability, and aesthetic concerns. The term gable wall or gable end more commonly refers to the entire wall, including the gable and the wall below it. Some types of roof do not have a gable (for example hip roofs do not). One common type of roof with gables, the gable roof, is named after its prominent gables. A parapet made of a series of curves (Dutch gable) or horizontal steps (crow-stepped gable) may hide the diagonal lines of the roof. Gable ends of more recent buildings are often treated in the same way as the Classic pediment form. But unlike Classical structures, which operate through trabeation, the gable ends of many buildings are actually bearing-wall structures. Gable style is also used in the design of fabric structures, with varying degree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historic American Engineering Record
Heritage Documentation Programs (HDP) is a division of the U.S. National Park Service (NPS) responsible for administering the Historic American Buildings Survey (HABS), Historic American Engineering Record (HAER), and Historic American Landscapes Survey (HALS). These programs were established to document historic places in the United States. Records consist of measured drawings, archival photographs, and written reports, and are archived in the Prints and Photographs Division of the Library of Congress. Historic American Buildings Survey In 1933, NPS established the Historic American Buildings Survey following a proposal by Charles E. Peterson, a young landscape architect in the agency. It was founded as a constructive make-work program for architects, draftsmen and photographers left jobless by the Great Depression. It was supported through the Historic Sites Act of 1935. Guided by field instructions from Washington, D.C., the first HABS recorders were tasked with docume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Library Of Congress
The Library of Congress (LOC) is the research library that officially serves the United States Congress and is the ''de facto'' national library of the United States. It is the oldest federal cultural institution in the country. The library is housed in three buildings on Capitol Hill in Washington, D.C.; it also maintains a conservation center in Culpeper, Virginia. The library's functions are overseen by the Librarian of Congress, and its buildings are maintained by the Architect of the Capitol. The Library of Congress is one of the largest libraries in the world. Its "collections are universal, not limited by subject, format, or national boundary, and include research materials from all parts of the world and in more than 470 languages." Congress moved to Washington, D.C., in 1800 after holding sessions for eleven years in the temporary national capitals in New York City and Philadelphia. In both cities, members of the U.S. Congress had access to the sizable collection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I-beam
An I-beam, also known as H-beam (for universal column, UC), w-beam (for "wide flange"), universal beam (UB), rolled steel joist (RSJ), or double-T (especially in Polish language, Polish, Bulgarian language, Bulgarian, Spanish language, Spanish, Italian language, Italian and German language, German), is a beam (structure), beam with an or -shaped cross section (geometry), cross-section. The horizontal elements of the are flanges, and the vertical element is the "web". I-beams are usually made of structural steel and are used in construction and civil engineering. The web resists shear forces, while the flanges resist most of the bending moment experienced by the beam. The Euler–Bernoulli beam equation shows that the I-shaped section is a very efficient form for carrying both bending and shearing (physics), shear loads in the plane of the web. On the other hand, the cross-section has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion ( ...

Abutment
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end which provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan. The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.Pevsner, N. (1970) ''Cornwall''; 2nd ed. Harmondsworth: Penguin; p. 245 The impost or abacus of a column in classical architecture may also serve as an abutment to an arch. The word derives from the verb "abut", meaning to "touch by means of a mutual border". Use in engineering An abutment may be us ...
