Toronto Ravine System
The Toronto ravine system is a distinctive feature of the city's geography, consisting of a network of deep ravines, which forms a large urban forest that runs through most of Toronto. The ravine system is the largest in any city in the world, with the ''Ravine and Natural Feature Protection Bylaw'' protecting approximately of public and privately-owned land. The ravine system has been presented as a central characteristic of the city, with the size of the ravine system leading Toronto to be described as "a city within a park". The ravine system began to take shape approximately 12,000 years ago at the end of the Last Glacial Period when the glaciers that once covered Toronto retreated northeast, leaving rivers and valleys in their place. Due to the topography of the ravine system, limited urban development occurred within it until the mid-19th century. During the late 19th and early 20th centuries, the ravine system underwent a number of changes and saw several infrastructure d ...

Rouge River (Ontario)
The Rouge River is a river in Markham, Pickering, Richmond Hill and Toronto in the Greater Toronto Area of Ontario, Canada. The river flows from the Oak Ridges Moraine to Lake Ontario at the eastern border of Toronto, and is the location of Rouge Park, the only national park in Canada within a municipality. At its southern end, the Rouge River is the boundary between Toronto and southwestern Pickering in the Regional Municipality of Durham. History The Rouge River is part of the Carolinian life zone that is found in Southern Ontario. After the eradication of both the Petun and the Wyandot (Huron), Senecas from New York attempted to establish/expand their fur trade activities by establishing a village named ''Gandechiagaiagon'' (recorded variously as "Gandatsekiagon", "Ganatsekwyagon", "Gandatchekiagon", or "Katabokokonk"), meaning "sand-cut" at the mouth of Rouge River. According to a 1796 list by English surveyor Augustus Jones, the Mississauga name for the river was ''Gi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Admiralty
Admiralty Lake was a proglacial lake in the basin of what is now Lake Ontario. The shoreline of Admiralty Lake was about lower than Lake Ontario. The shoreline of Glacial Lake Iroquois, an earlier proglacial lake, was much higher than Lake Ontario's, because a lobe of the Laurentian Glacier blocked what is now the valley of the St Lawrence River. Lake Iroquois drained over the Niagara Escarpment, and down the Mohawk River. When the lobe of the glacier retreated the weight of the glacier kept the outlet of the St Lawrence River lower than the current level. As the glacier continued to retreat the region of the Thousand Islands rebounded, and the lake filled to its current level. References Bibliography *"Nearshore Geology". Aquatichabitat.ca.

Taddle Creek
Taddle Creek is a buried stream in Toronto, Ontario, Canada that flowed a southeasterly course about six kilometres long, from St. Clair Avenue west of Bathurst Street through the present site of Wychwood Park, through the University of Toronto, into the Toronto Harbour near the Distillery District. During the 19th century, it was buried and converted into an underground sewer, but traces of the creek can still be found today. The scenic footpath known as Philosopher's Walk follows the ravine created by the creek from the Royal Ontario Museum to Trinity College. ''Taddle Creek'' is also the name of a Toronto literary magazine and of a local Montessori school. History In the 1790s, the original town site of the Town of York was established along its south bank. Its waters would be used by its first industries. The disappearance of the creek came in phases in the 19th century: * east of Church Street - before 1860 * Elizabeth Street to Church Street - early 1866 * University of To ...

Garrison Creek (Ontario)
Garrison Creek was a short stream about long that flowed southeast into the west side of Toronto Harbour in Ontario, Canada. It has been largely covered over and filled in, but geographical traces of the creek can still be found, including the natural amphitheatre known as Christie Pits and the off-leash dog "bowl" of Trinity Bellwoods Park. The name ''"Garrison Creek"'' was used because Fort York was built near the creek mouth. Volunteers lead popular tours of the course of the old watershed. History Garrison Creek was one of a number of small natural watercourses on the site of the current city of Toronto. Starting in the 1870s, the stream was diverted into underground sewers under city streets and the original course was filled in with soil. By 1920, the stream was entirely diverted into the sewer system. There are many artifacts of the Creek's existence, including buried bridges along Harbord Street and Crawford Street south of Dundas Street. The unusual courses of Niagar ...

Port Lands
The Port Lands (also known as Portlands) of Toronto, Ontario, Canada are an industrial and recreational neighbourhood located about 5 kilometres south-east of downtown, located on the former Don River delta and most of Ashbridge's Bay. Approximate geographical borders are the Gardiner Expressway/Don Valley Parkway ramps to the north and west, Lake Shore Boulevard to the north, Lake Ontario on the three remaining sides: the Inner Harbour to the west, Ashbridge's Bay to the east and the open waters of Lake Ontario to the south.

Subterranean River
A subterranean river is a river that runs wholly or partly beneath the ground surface – one where the riverbed does not represent the surface of the Earth. It is distinct from an aquifer, which may flow like a river but is contained within a permeable layer of rock or other unconsolidated materials. A river flowing below ground level in an open gorge is not classed as subterranean. Subterranean rivers may be entirely natural, flowing through cave systems. In karst topography, rivers may disappear through sinkholes, continuing underground. In some cases, they may emerge into daylight further downstream. The longest subterranean river in the world is the Sistema Sac Actun cave system in Mexico. Subterranean rivers can also be the result of covering over a river or diverting its flow into culverts, usually as part of urban development.Richard J.

York, Upper Canada
York was a town and second capital of the colony of Upper Canada. It is the predecessor to the Old Toronto, old city of Toronto (1834–1998). It was established in 1793 by Lieutenant-Governor John Graves Simcoe as a "temporary" location for the capital of Upper Canada, while he made plans to build a capital near today's London, Ontario. Simcoe renamed the location York after Prince Frederick, Duke of York and Albany, George III of the United Kingdom, George III's second son. Simcoe gave up his plan to build a capital at London, and York became the permanent capital of Upper Canada on February 1, 1796. That year Simcoe returned to Britain and was temporarily replaced by Peter Russell (politician), Peter Russell. The original townsite was a compact ten blocks near the mouth of the Don River (Ontario), Don River and a Fort York, garrison was built at the channel to Toronto Harbour. Government buildings and a law court were established. Yonge Street was built, connecting York to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castle Frank, By Elizabeth Simcoe, 1796-Archives-of-Ontario
A castle is a type of fortified structure built during the Middle Ages predominantly by the nobility or royalty and by military orders. Scholars debate the scope of the word ''castle'', but usually consider it to be the private fortified residence of a lord or noble. This is distinct from a palace, which is not fortified; from a fortress, which was not always a residence for royalty or nobility; from a ''pleasance'' which was a walled-in residence for nobility, but not adequately fortified; and from a fortified settlement, which was a public defence – though there are many similarities among these types of construction. Use of the term has varied over time and has also been applied to structures such as hill forts and 19th-20th century homes built to resemble castles. Over the approximately 900 years when genuine castles were built, they took on a great many forms with many different features, although some, such as curtain walls, arrowslits, and portcullises, were ...
