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 ...

Babi Yar
Babi Yar (russian: Ба́бий Яр) or Babyn Yar ( uk, Бабин Яр) is a ravine in the Ukrainian capital Kyiv and a site of massacres carried out by Nazi Germany's forces during its campaign against the Soviet Union in World War II. The first and best documented of the massacres took place on 29–30 September 1941, killing some 33,771 Jews. The decision to murder all the Jews in Kyiv was made by the military governor ''Generalmajor'' Kurt Eberhard, the Police Commander for Army Group South, SS-''Obergruppenführer'' Friedrich Jeckeln, and the ''Einsatzgruppe'' C Commander Otto Rasch. Sonderkommando 4a as the sub-unit of ''Einsatzgruppe'' C, along with the aid of the ''SD'' and Order Police battalions with the Ukrainian Auxiliary Police backed by the '' Wehrmacht'', carried out the orders. Sonderkommando 4a and the 45th Battalion of the German Order Police conducted the shootings. Servicemen of the 303rd Battalion of the German Order Police at this time guarded the oute ...

Ravenna Park
Ravenna Park and Cowen Park comprise a single contiguous recreation and green space in the Ravenna neighborhood of Seattle, Washington in the United States. These public parks encompass the ravine with a maximum depth of through which Ravenna Creek flows. History The ravine that is the central feature of Cowen and Ravenna Park was formed when melt-off from the Vashon Glacial Ice Sheet formed Lake Russell and proceeded to cut drainage ravines through new glacial fill. Lake Russell disappeared when the ice sheet retreated north of the Strait of Juan de Fuca, but some features remained, including the Green Lake drainage basin, which continued to empty through the Ravenna ravine into Lake Washington. The deeper pockets of the basin became Bitter Lake, Haller Lake and Green Lake. Many creeks and brooks and springs fed into Green Lake, whose outlet was on the east side of the route of Ravenna Boulevard, in a deepening ravine which became Cowen and Ravenna parks. Ravenna Creek' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canyon
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examples of mountai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gill (ravine)
A gill or ghyll is a ravine or narrow valley in the North of England and other parts of the United Kingdom. The word originates from the Old Norse . Examples include Dufton Ghyll Wood, Dungeon Ghyll, Troller's Gill and Trow Ghyll. As a related usage, Gaping Gill is the name of a cave, not the associated stream, and Cowgill, Masongill and Halton Gill are derived names of villages. The stream flowing through a gill is often referred to as a beck: for example in Swaledale, Gunnerside Beck flows through Gunnerside Ghyll. ''Beck ''is also used as a more general term for streams in the north of England – examples include Ais Gill Beck, Arkle Beck and Peasey Beck. In the North Pennines, the word sike or syke is found in similar circumstances. This is particularly common in the Appleby Fells area where sikes significantly outnumber the becks and gills; it can also be seen in the name of Eden Sike Cave in Mallerstang. In the High Weald gills are deeply cut ravines, usually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rauðfeldsgjá
Rauðfeldsgjá () is a ravine in Snæfellsnes Peninsula in Iceland. Name The ravine is mentioned in the Icelandic saga, ''Bárðar saga Snæfellsáss ''Bárðar saga Snæfellsáss'' (14th c. Middle Icelandic: ; Modern Icelandic: ) or ''Bárðar saga Snæfellsáss ok Gests'' is a late saga of the Icelanders with legendary elements. It falls into two sections, one about Bárðr and the other a ...'', which was written around 600 years ago about events that occurred about 12 centuries ago. In the story, Bárður, in anger over the loss of his daughter, throws the two brothers Rauðfeldur and Sölvi off the cliff and into the ravine.

Gravina In Puglia
Gravina in Puglia (; nap, label= Barese, Gravéine ; la, Silvium; grc, Σιλούϊον, Siloúïon) is a town and ''comune'' of the Metropolitan City of Bari, Apulia, southern Italy. The word ''gravina'' comes from the Latin ''grava'' or from the messapic ''graba'', with the meaning of ''rock'', ''shaft'' and ''erosion of bank river''. Other words that share the same root are ''grava'', ''gravaglione'' and ''gravinelle''. Alternatively, when the emperor Frederick II went to Gravina, because of the large extension of the lands and for the presence of wheat, he decided to give to it the motto ''Grana dat et vina.'', that is to say ''It offers wheat and wine.''. Gravina is the home of the Alta Murgia National Park. History Thanks to its strategic position, Gravina has a very ancient history. Its territory has been inhabited since the Paleolithic, due to the high presence of water and woods. The largest remains date back to the Neolithic. The oldest settlements have been identif ...

Stream
A stream is a continuous body of surface water flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighted subterranean water, and surfaced groundwater (spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls. Streams are important as conduits in the water cycle, instruments in groundwater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Valley
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. Fo ...
