Ravine in the context of "Naukluft Mountains"

The Massif de l'Esterel (Occitan Provençal: Esterèu; English: Esterel Massif) is a Mediterranean coastal mountain range in the departments of Var and Alpes-Maritimes on the French Riviera. Neighbouring cities are Mandelieu-la-Napoule and Cannes on the east, as well as Saint-Raphaël and Fréjus on the west.

The soil and rocks of the range are of volcanic origin, composed mainly of rhyolite, which gives the hills a red color. The terrain is rugged, with deep ravines and oak forests. The highest point of the massif is Mont Vinaigre (618 metres or 2,028 feet).

Amalfi (UK: /əˈmælfi/, US: /ɑːˈmɑːlfi/, Italian: [aˈmalfi]) is a town and comune in the province of Salerno, in the region of Campania, Italy, on the Gulf of Salerno. It lies at the mouth of a deep ravine, at the foot of Monte Cerreto (1,315 metres, 4,314 feet), surrounded by dramatic cliffs and coastal scenery. The town of Amalfi was the capital of the maritime republic known as the Duchy of Amalfi, an important trading power in the Mediterranean between 839 and around 1200. It has 4,611 inhabitants.

The town became a popular seaside resort beginning in the Edwardian era, with members of the British upper class spending their winters in Amalfi. Amalfi is included in the UNESCO World Heritage Sites.

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 110 square kilometres (42 sq mi) 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 and left valleys and rivers that eventually formed deep ravines. Due to the topography of the ravine system, limited urban development occurred within it until the mid-19th century. Limited development continued in the ravine system until the occurrence of Hurricane Hazel in 1954. The destruction caused by the hurricane led to a halt to major developments within the ravine system. The Toronto ravine system remains largely undeveloped, with most of its public lands having been designated as parkland.

Badlands are a type of dry terrain where softer sedimentary rocks and clay-rich soils have been extensively eroded. They are characterized by steep slopes, minimal vegetation, lack of a substantial regolith, and high drainage density. Ravines, gullies, buttes, hoodoos and other such geologic forms are common in badlands.

Badlands are found on every continent except Antarctica, being most common where there are unconsolidated sediments. They are often difficult to navigate by foot, and are unsuitable for agriculture. Most are a result of natural processes, but destruction of vegetation by overgrazing or pollution can produce anthropogenic badlands.

Tyropoeon Valley (Greek: φάραγξ τῶν τυροποιῶν pharanx tōn tyropoiōn i.e., "Valley of the Cheesemakers" or "Cheesemongers") is the name given by the first-century Jewish-Roman historian Josephus (Wars 5.140) to the valley or rugged ravine, which in his times separated Jerusalem's Temple Mount (Mount Moriah) from the Western Hill or Mount Zion, and emptied into the valley of Hinnom. In modern scholarly terms it is also known as the central valley/Central Valley of Jerusalem.

Babi Yar (Russian: Бабий Яр) or Babyn Yar (Ukrainian: 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, in which some 33,771 Jews were murdered. Other victims of massacres at the site included Soviet prisoners of war, communists and Romanies. It is estimated that a total of between 100,000 and 150,000 people were murdered at Babi Yar during the German occupation.

The decision to murder all the Jews in Kiev was made by the German 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 outer perimeter of the execution site.

An armoured vehicle-launched bridge (AVLB), also known as a bridgelayer (especially for nonarmoured variants), or tank bridge, is a combat support vehicle, sometimes regarded as a subtype of military engineering vehicle, designed to assist militaries in rapidly deploying tanks and other armoured fighting vehicles across gap-type obstacles, such as rivers. The AVLB is usually a tracked vehicle converted from a tank chassis to carry a folding metal bridge instead of weapons. The AVLB's job is to allow armoured or infantry units to cross craters, anti-tank ditches, blown bridges, railroad cuts, canals, rivers and ravines. When a river too deep for vehicles to wade through is reached, and no bridge is conveniently located, or sufficiently sturdy, a substantial concern when moving 60-ton tanks.

The bridge layer unfolds and launches its cargo, providing a ready-made bridge across the obstacle in only minutes. Once the span has been put in place, the AVLB vehicle detaches from the bridge, and moves aside to allow traffic to pass. Once all of the vehicles have crossed, it crosses the bridge itself and reattaches to the bridge on the other side. It then retracts the span ready to move off again. A similar procedure can be employed to allow crossings of small chasms or similar obstructions.

The Castalian Spring, in the ravine between the Phaedriades at Delphi, is where all visitors to Delphi — the contestants in the Pythian Games, and especially pilgrims who came to consult the Delphic Oracle — stopped to wash themselves and quench their thirst; it is also here that the Pythia and the priests cleansed themselves before the oracle-giving process. Finally Roman poets regarded it as a source of poetic inspiration. According to some mythological versions it was here that Apollo killed the monster, Python, who was guarding the spring, and that is why it was considered to be sacred.

The Longyear Valley (Norwegian: Longyeardalen) is a valley and ravine in Svalbard. It slightly winds 40 kilometres (25 mi) WNW ending in Adventfjorden, facing west, the broadest inlet of Spitsbergen, the main landmass. It has a few wind gaps to the south and north-east over small glaciers, under which small streams form. It is between mountains Platåberget and Gruvefjellet. The town of Longyearbyen is at its foot, which is named for the American industrialist John Munro Longyear. The Longyear River is, like all the island's rivers, silted from surrounding glaciers.
