Eramosa Karst
The Eramosa Karst is a provincially significant Earth Science Area of Natural and Scientific Interest in Ontario, Canada, located in Stoney Creek, a constituent community of the City of Hamilton, and immediately south of the Niagara Escarpment. It exhibits sixteen different karstic geological features, of which seven are provincially significant, and is considered to be the best example of karst topography found in Ontario. The area is composed of parcels of land that are provincially, municipally and privately owned. It received ANSI-ES designation on February 13, 2003. Conservation area In October 2006, Ontario donated 73 ha of land to the Hamilton Conservation Authority to create a new conservation area, followed by another donation of 3.1 ha in April 2007. The City of Hamilton has also contributed in June 2007 by transferring 1.6 ha. The area opened to the public on June 20, 2008. Landform The area is crossed by the Eramosa Escarpment. It is morphologically similar to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Dolomite (rock)
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2. It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 million years in age). The first geologist to distinguish dolomite rock from limestone was Belsazar Hacquet in 1778. Most dolomite was formed as a magnesium replacement of limestone or of lime mud before lithification. The geological process of conversion of calcite to dolomite is known as dolomitization and any intermediate product is known as dolomitic limestone. The "dolomite problem" refers to the vast worldwide depositions of dolomite in the past geologic record in contrast to the limited amounts of dolomite formed in modern times. Recent research has revealed sulfate-reducing bacteria living in anoxic conditions precipitate dolomite which ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Areas Of Natural And Scientific Interest
Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or ''plane area'' refers to the area of a shape or planar lamina, while ''surface area'' refers to the area of an open surface or the boundary of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analogue of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept). The area of a shape can be measured by comparing the shape to squares of a fixed size. In the International System of Units (SI), the standard unit of area is the square metre (written as m2), which is the area of a square whose sides are one metre long. A shape with an area of three square metres would have the same area as three such squares. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bruce Trail
The Bruce Trail is a hiking trail in southern Ontario, Canada, from the Niagara River to the tip of Tobermory, Ontario. The main trail is more than long and there are over of associated side trails. The trail mostly follows the edge of the Niagara Escarpment, one of the nineteen UNESCO World Biosphere Reserves in Canada. The land the trail traverses is owned by the Government of Ontario, local municipalities, local conservation authorities, private landowners, and the Bruce Trail Conservancy (BTC). The Bruce Trail is the oldest and longest marked hiking trail in Canada. Its name is linked to the Bruce Peninsula and Bruce County, through which the trail runs. The trail is named after the county, which was named after James Bruce, 8th Earl of Elgin who was Governor General of the Province of Canada from 1847 to 1854. History The idea for creating the Bruce Trail came about in 1959 out of a meeting between Ray Lowes and Robert Bateman, of the Federation of Ontario Naturalists. Ra ...

Felker's Falls
The city of Hamilton in Ontario, Canada is home to more than 100 waterfalls and cascades, most of which are on or near the Bruce Trail as it winds through the Niagara Escarpment. Ontario's internationally recognized Niagara Escarpment provides perfect geological conditions for waterfalls to occur, from Tobermory to Niagara Falls. With its crest, Webster's Falls is the largest waterfall within the city. Tew's Falls is a ribbon waterfall, and is the tallest waterfall found in Hamilton. Both Webster's and Tew's are located at the Spencer Gorge / Webster's Falls Conservation Area. Albion Falls was once seriously considered as a possible source of water for Hamilton. Rocks from the Albion Falls area were used in the construction of the Royal Botanical Gardens' Rock Garden. There used to be more waterfalls in Hamilton than exist today. Many of the waterfalls in central Hamilton slowly vanished as population and construction on Hamilton Mountain increased. As well, in the early y ...

Sinkhole
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are locally also known as ''vrtače'' and shakeholes, and to openings where surface water enters into underground passages known as ''ponor'', swallow hole or swallet. A ''cenote'' is a type of sinkhole that exposes groundwater underneath. A ''sink'' or ''stream sink'' are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock. Most sinkholes are caused by karst processes – the chemical dissolution of carbonate rocks, collapse or suffosion processes. Sinkholes are usually circular and vary in size from tens to hundreds of meters both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may form gradually or suddenly, and are found worldwide. Formation Natural processes Sinkholes may capture surf ...

Till

Note that the larger grains (pebbles and gravel) in the till are completely surrounded by the matrix of finer material (silt and sand), and this characteristic, known as ''matrix support'', is diagnostic of till. image:Glacial till exposed in roadcut-750px.jpg, Glacial till with tufts of grass Till or glacial till is unsorted glacier, glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes. Description Till is a form of '' glacial drift'', which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. It is distinguished from other forms of drift in that it is depos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bedrock
In geology, bedrock is solid Rock (geology), rock that lies under loose material (regolith) within the crust (geology), crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysics, geophysical methods is an important task in most civil engineering projects. Superficial deposition (geology), deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave ...

Hamilton, Ontario
Hamilton is a port city in the Canadian province of Ontario. Hamilton has a population of 569,353, and its census metropolitan area, which includes Burlington and Grimsby, has a population of 785,184. The city is approximately southwest of Toronto in the Greater Toronto and Hamilton Area (GTHA). Conceived by George Hamilton when he purchased the Durand farm shortly after the War of 1812, the town of Hamilton became the centre of a densely populated and industrialized region at the west end of Lake Ontario known as the Golden Horseshoe. On January 1, 2001, the current boundaries of Hamilton were created through the amalgamation of the original city with other municipalities of the Regional Municipality of Hamilton–Wentworth. Residents of the city are known as Hamiltonians. Traditionally, the local economy has been led by the steel and heavy manufacturing industries. During the 2010s, a shift toward the service sector occurred, such as health and sciences. Hamilton is ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
