The Three Sisters is a small mountain range found in the Mojave Desert, in Los Angeles County, California. [1] It consists of three main hills of varying sizes, with the smallest to the southwest having a height above surrounding land of 150 feet (46 m), the second 180 feet (55 m), and the third and largest to the northeast having a height of 290 feet (88 m). They three main hills are the highly eroded remnants of what used to be the peaks of the northern San Gabriel Mountains, before recent sediment filled the area.
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. A mountain differs from a plateau in having a limited summit area, and is larger than a hill, typically rising at least 300 metres above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges.
A Munro is defined as a mountain in Scotland with a height over 3,000 feet (914.4 m), and which is on the Scottish Mountaineering Club (SMC) official list of Munros; there is no explicit topographical prominence requirement. The best known Munro is Ben Nevis, the highest mountain in the British Isles at 4,413 feet (1,345 m).
A roller coaster is a type of amusement ride that employs a form of elevated railroad track designed with tight turns, steep slopes, and sometimes inversions. People ride along the track in open cars, and the rides are often found in amusement parks and theme parks around the world. LaMarcus Adna Thompson obtained one of the first known patents for a roller coaster design in 1885, related to the Switchback Railway that opened a year earlier at Coney Island. The track in a coaster design does not necessarily have to be a complete circuit, as shuttle roller coasters demonstrate. Most roller coasters have multiple cars in which passengers sit and are restrained. Two or more cars hooked together are called a train. Some roller coasters, notably Wild Mouse roller coasters, run with single cars.
In topography, prominence measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. A peak's key col is a unique point on this contour line and the parent peak is some higher mountain, selected according to various criteria.
Disney's Blizzard Beach is a water theme park located at the Walt Disney World Resort in Bay Lake, Florida near Orlando. All water areas are heated, with the exception of the melting snow in the ice cave of Cross Country Creek.
In these lists of mountains in Ireland, those within Northern Ireland, or on the Republic of Ireland – United Kingdom border, are marked with an asterisk, while the rest are within the Republic of Ireland. Where mountains are ranked by height, the definition of the topographical prominence used to classify the mountain, is noted. In British definitions, a height of 600 metres (1,969 ft) is required for a mountain, whereas in Ireland, a lower threshold of 500 metres (1,640 ft) is sometimes advocated.
A hill is a landform that extends above the surrounding terrain. It often has a distinct summit.
Scotland is the most mountainous country in the United Kingdom. Scotland's mountain ranges can be divided, in a roughly north to south direction, into: the Scottish Highlands and the Central Belt and Southern Uplands in the Scottish Lowlands. The highlands contains the country's main mountain ranges, but many hills and mountains are to be found south of these as well. The highlands includes Britain's loftiest peaks, the Munros, the highest being Ben Nevis at 1,344.53 m. The below lists are not exhaustive; there are countless subranges throughout the country.
The mountains and hills of the British Isles are categorised into various lists based on different combinations of elevation, prominence, and other criteria such as isolation. These lists are used for peak bagging, whereby hillwalkers attempt to reach all the summits on a given list, the oldest being the 282 Munros in Scotland, created in 1891.
Sgùrr na Ciste Duibhe is a Scottish mountain situated on the northern side of Glen Shiel, 27 kilometres south east of Kyle of Lochalsh in the Highland council area.
The mountains and hills of England comprise very different kinds of terrain, from a mountain range which reaches almost 1,000 metres high, to several smaller areas of lower mountains, foothills and sea cliffs. Most of the major upland areas have been designated as Areas of Outstanding Natural Beauty (AONB) or national parks. The highest and most extensive areas are in the north and west, while the midlands, south-east and east of the country tend to be low-lying.
