Buckel's Bog
Buckel's Bog was a 160-acre, shallow periglacial lake or a glade that occupied the headwater region of the North Branch of the Casselman River in Garrett County, Maryland, during the late Pleistocene epoch. It is the remnant of the only known natural lake in Maryland. The eastern side of the remaining evidence of Buckel's Bog is presently traversed by the Casselman River as its waters flow northward into Pennsylvania. In the nineteenth century, the fledgling United States began its westward expansion; the National Road The National Road (also known as the Cumberland Road) was the first major improved highway in the United States built by the federal government. Built between 1811 and 1837, the road connected the Potomac and Ohio Rivers and was a main tran ... was one artery proposed and constructed to facilitate this westward flow. The proposed road would cross the Casselman River just south of Buckel's Bog, so the (at that time) country's largest stone-arch bridge was ...

Garrett County, Maryland
Garrett County () is the westernmost county of the U.S. state of Maryland, completely within the Appalachian Mountains. As of the 2020 United States census, the population was 28,806, making it the third-least populous county in Maryland. Its county seat is Oakland. The county was named for John Work Garrett (1820–1884), president of the Baltimore and Ohio Railroad. Created from Allegany County in 1872, it was the last county to be formed in the state. The county is part of the Western Maryland region of the state. Garrett County is bordered by four West Virginia counties and to the north the Maryland–Pennsylvania boundary known as the Mason–Dixon line. The eastern border with Allegany County was defined by the Bauer Report, submitted to Governor Lloyd Lowndes, Jr. on November 9, 1898. The Potomac River and State of West Virginia lie to the south and west. Garrett County lies in the Allegheny Mountains, which here form the western flank of the Appalachian ...

Glade (geography)
In the most general sense, a glade or clearing is an open area within a forest. Glades are often grassy meadows under the canopy of deciduous trees such as Alnus rubra, red alder or Populus tremuloides, quaking aspen in western North America. They also represent openings in forests where local conditions such as avalanches, poor soils, or fire damage have created semipermanent clearings. They are very important to Herbivore, herbivorous animals, such as deer and elk, for forage and hibernation, denning activities. Sometimes the word is used in a looser sense, as in the treeless wetlands of the Everglades of Florida. In the central United States, Calcareous glade, calcareous glades occur with rocky, prairie-like habitats in areas of shallow soil. Glades are characterized by unique plant and animal communities that are adapted to harsh and dry conditions.

Periglaciation
Periglaciation (adjective: "periglacial", referring to places at the edges of glacial areas) describes geomorphic processes that result from seasonal thawing and freezing, very often in areas of permafrost. The meltwater may refreeze in ice wedges and other structures. "Periglacial" originally suggested an environment located on the margin of past glaciers. However, freeze and thaw cycles influence landscapes also outside areas of past glaciation. Therefore, periglacial environments are anywhere when freezing and thawing modify the landscape in a significant manner. History Periglaciation became a distinct subject within the study of geology after Walery Łoziński, a Polish geologist, introduced the term in 1909. Łoziński drew upon the early work of Johan Gunnar Andersson. According to Alfred Jahn, his introduction of his work at the 1910 International Geological Congress held in Stockholm caused significant discussion. In the field trip to Svalbard that followed the congres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Casselman River
The Casselman River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed August 15, 2011 tributary of the Youghiogheny River in western Maryland and Pennsylvania in the United States.Gertler, Edward. ''Keystone Canoeing'', Seneca Press, 2004. The Casselman River drains an area of 576 square miles. The river has been used for transportation across the Allegheny Mountains, between the cities of Baltimore and Washington, D.C., in the east and Pittsburgh in the west. Two railroads followed the Casselman River from Meyersdale, Pennsylvania, to Confluence. First is the B&O Railroad, running between Baltimore and Pittsburgh, which was completed in 1871, and is currently owned by CSX. Second is the Western Maryland Railway, which ran from Cumberland, Maryland, to Connellsville, Pennsylvania. Although the Western Maryland was abandoned in the 1980s, the right-of-way has been converted into the Great Allegheny Passage, a rail ...

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

National Road
The National Road (also known as the Cumberland Road) was the first major improved highway in the United States built by the federal government. Built between 1811 and 1837, the road connected the Potomac and Ohio Rivers and was a main transport path to the West for thousands of settlers. When improved in the 1830s, it became the second U.S. road surfaced with the macadam process pioneered by Scotsman John Loudon McAdam. Construction began heading west in 1811 at Cumberland, Maryland, on the Potomac River. After the Financial Panic of 1837 and the resulting economic depression, congressional funding ran dry and construction was stopped at Vandalia, Illinois, the then-capital of Illinois, northeast of St. Louis across the Mississippi River. The road has also been referred to as the Cumberland Turnpike, the Cumberland–Brownsville Turnpike (or Road or Pike), the Cumberland Pike, the National Pike, and the National Turnpike. In the 20th century with the advent of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casselman Bridge
The Casselman Bridge is a historic transportation structure on the Casselman River, located immediately east of Grantsville in Garrett County, Maryland, and preserved by the state of Maryland as Casselman River Bridge State Park. The bridge was built in 1813–1814 as part of the National Road. Historic markers posted at each end read: The structure, which has also been known as Casselmans Bridge, Castleman's Bridge, and Little Crossings Bridge, was declared a National Historic Landmark in 1964 and placed on the National Historic Register in 1966. History The stone arch bridge spans with a arch and a roadway width of . The bridge was constructed in 1813–1814 to aid in the westward movement through the frontier wilderness west of Cumberland, Maryland. The first wheeled vehicles crossed the bridge in 1815. As a "tidal wave" of western expansion followed the opening of the National Road, Casselman Bridge had heavy traffic that included 10-ton loads drawn by 12-horse teams. ...
