Summit
–
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. Mathematically, a summit is a maximum in elevation. The topographic terms acme, apex, peak, and zenith are synonymous, the UIAA definition is that a summit is independent if it has a prominence of 30 metres or more, it is a mountain if it has a prominence of at least 300 metres. This can be summarised as follows, A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top, Summit may also refer to the highest point along a line, trail, or route. In many parts of the western United States, the term refers to the highest point along a road, highway. For example, the highest point along Interstate 80 in California is referred to as Donner Summit while the highest point on Interstate 5 is Siskiyou Mountain Summit, geoid Hill List of highest mountains Maxima and minima Nadir Summit accordance Peak finder

Topographic prominence
–
It is a measure of the independence of a summit. A peaks key col is a point on this contour line. By convention, the prominence of Mount Everest, the Earths highest mountain, is taken to equal the elevation of its summit above sea level, if the peaks prominence is P metres, to get from the summit to any higher terrain one must descend at least P metres. Together with the convention for Mount Everest, this implies that the prominence of any island or continental highpoint is equal to its elevation above sea level, for every ridge connecting the peak to higher terrain, find the lowest point on the ridge. The key col is defined as the highest of these cols, the prominence is the difference between the elevation of the peak and the elevation of the key col. The following mental exercise may illustrate the meaning of topographic prominence, imagine you are standing at the top of a peak and imagine that an imaginary sea level rises to your feet. Now slowly lower the sea level and an imaginary island appears beneath your feet. Your island will grow and will merge with other islands that emerge, the parent peak may be either close or far from the subject peak. The summit of Mount Everest is the parent peak of Aconcagua at a distance of 17,755 km, the key col may also be close or far from the subject peak. The key col for Aconcagua is the Bering Strait at a distance of 13,655 km, the key col for the South Summit of Mount Everest is about 100 m distant. Prominence is interesting to many mountaineers because it is a measurement that is strongly correlated with the subjective significance of a summit. Peaks with low prominences are either subsidiary tops of some higher summit or relatively insignificant independent summits, peaks with high prominences tend to be the highest points around and are likely to have extraordinary views. Only summits with a sufficient degree of prominence are regarded as independent mountains, for example, the worlds second-highest mountain is K2. While Mount Everests South Summit is taller than K2, it is not considered an independent mountain because it is a subsummit of the main summit, many lists of mountains take topographic prominence as a criterion for inclusion, or cutoff. John and Anne Nuttalls The Mountains of England and Wales uses a cutoff of 15 m, in the contiguous United States, the famous list of fourteeners uses a cutoff of 300 ft /91 m. Also in the U. S.2000 feet of prominence has become a threshold that signifies that a peak has major stature. This generates lists of peaks ranked by prominence, which are different from lists ranked by elevation. Such lists tend to emphasize isolated high peaks, such as range or island high points, one advantage of a prominence-ranked list is that it needs no cutoff, since a peak with high prominence is automatically an independent peak

Ultra-prominent peak
–
An ultra-prominent peak, or Ultra for short, is defined as a mountain summit with a topographic prominence of 1,500 metres or more. There are approximately 1,524 such peaks on Earth, some peaks, such as the Matterhorn and Eiger, are not Ultras because they are connected to higher mountains by high cols and therefore do not achieve enough topographic prominence. The term Ultra is due to earth scientist Stephen Fry, from his studies of the prominence of peaks in Washington in the 1980s and his original term was ultra major mountain, referring to peaks with at least 5,000 ft of prominence. Currently,1,515 Ultras have been identified worldwide,637 in Asia,355 in North America,209 in South America,119 in Europe,84 in Africa,69 in Australasia and 39 in Antarctica. Many of the worlds largest mountains are Ultras, including Mount Everest, K2, Kilimanjaro, Mont Blanc, on the other hand, others such as the Eiger and the Matterhorn are not Ultras because they do not have sufficient prominence. In British Columbia, some of the mountains listed do not even have generally recognized names, a number of Ultras have yet to be climbed, with Sauyr Zhotasy, Mount Siple, and Gangkar Puensum being the most likely candidates for the most prominent unclimbed mountain in the world. All of the Seven Summits are Ultras by virtue of the fact that they are the points of large landmasses. Each has its key col at or near sea level, resulting in a value almost equal to its elevation. List of peaks by prominence gives the 125 most prominent peaks worldwide

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Delphi
–
Delphi is famous as the ancient sanctuary that grew rich as the seat of the oracle that was consulted on important decisions throughout the ancient classical world. Moreover, it was considered as the navel of the world by the Greeks as represented by the Omphalos and it occupies an impressive site on the south-western slope of Mount Parnassus overlooking the coastal plain to the south and the valley of Phocis. It is now an archaeological site and the modern town is nearby. The site of Delphi is located in upper central Greece, on multiple plateaux/terraces along the slope of Mount Parnassus, and includes the Sanctuary of Apollo and this semicircular spur is known as Phaedriades, and overlooks the Pleistos Valley. In myths dating to the period of Ancient Greece, the site of Delphi was believed to be determined by Zeus when he sought to find the centre of his Grandmother Earth. He sent two eagles flying from the eastern and western extremities, and the path of the eagles crossed over Delphi where the omphalos, Apollo was said to have slain Python, a drako a serpent or a dragon who lived there and protected the navel of the Earth. Python is claimed by some to be the name of the site in recognition of Python which Apollo defeated. The Homeric Hymn to Delphic Apollo recalled that the ancient name of this site had been Krisa, others relate that it was named Pytho and that Pythia, the priestess serving as the oracle, was chosen from their ranks by a group of priestesses who officiated at the temple. At the settlement site in Delphi, which was a settlement of the late 9th century. Pottery and bronze work as well as tripod dedications continue in a steady stream, the victors at Delphi were presented with a laurel crown which was ceremonially cut from a tree by a boy who re-enacted the slaying of the Python. Delphi was set apart from the other sites because it hosted the mousikos agon. These Pythian Games rank second among the four stephanitic games chronologically and these games, though, were different from the games at Olympia in that they were not of such vast importance to the city of Delphi as the games at Olympia were to the area surrounding Olympia. Delphi would have been a renowned city whether or not it hosted these games, it had other attractions that led to it being labeled the omphalos of the earth, in other words, in the inner hestia of the Temple of Apollo, an eternal flame burned. The name Delphoi comes from the root as δελφύς delphys, womb. Apollo is connected with the site by his epithet Δελφίνιος Delphinios, the epithet is connected with dolphins in the Homeric Hymn to Apollo, recounting the legend of how Apollo first came to Delphi in the shape of a dolphin, carrying Cretan priests on his back. The Homeric name of the oracle is Pytho, another legend held that Apollo walked to Delphi from the north and stopped at Tempe, a city in Thessaly, to pick laurel which he considered to be a sacred plant. In commemoration of this legend, the winners at the Pythian Games received a wreath of laurel picked in the Temple, Delphi became the site of a major temple to Phoebus Apollo, as well as the Pythian Games and the famous prehistoric oracle. Even in Roman times, hundreds of votive statues remained, described by Pliny the Younger, additionally, according to Plutarchs essay on the meaning of the E at Delphi—the only literary source for the inscription—there was also inscribed at the temple a large letter E

Greece
–
Greece, officially the Hellenic Republic, historically also known as Hellas, is a country in southeastern Europe, with a population of approximately 11 million as of 2015. Athens is the capital and largest city, followed by Thessaloniki. Greece is strategically located at the crossroads of Europe, Asia, situated on the southern tip of the Balkan peninsula, it shares land borders with Albania to the northwest, the Republic of Macedonia and Bulgaria to the north, and Turkey to the northeast. Greece consists of nine regions, Macedonia, Central Greece, the Peloponnese, Thessaly, Epirus, the Aegean Islands, Thrace, Crete. The Aegean Sea lies to the east of the mainland, the Ionian Sea to the west, the Cretan Sea and the Mediterranean Sea to the south. Greece has the longest coastline on the Mediterranean Basin and the 11th longest coastline in the world at 13,676 km in length, featuring a vast number of islands, eighty percent of Greece is mountainous, with Mount Olympus being the highest peak at 2,918 metres. From the eighth century BC, the Greeks were organised into various independent city-states, known as polis, which spanned the entire Mediterranean region and the Black Sea. Greece was annexed by Rome in the second century BC, becoming a part of the Roman Empire and its successor. The Greek Orthodox Church also shaped modern Greek identity and transmitted Greek traditions to the wider Orthodox World, falling under Ottoman dominion in the mid-15th century, the modern nation state of Greece emerged in 1830 following a war of independence. Greeces rich historical legacy is reflected by its 18 UNESCO World Heritage Sites, among the most in Europe, Greece is a democratic and developed country with an advanced high-income economy, a high quality of life, and a very high standard of living. A founding member of the United Nations, Greece was the member to join the European Communities and has been part of the Eurozone since 2001. Greeces unique cultural heritage, large industry, prominent shipping sector. It is the largest economy in the Balkans, where it is an important regional investor, the names for the nation of Greece and the Greek people differ from the names used in other languages, locations and cultures. The earliest evidence of the presence of human ancestors in the southern Balkans, dated to 270,000 BC, is to be found in the Petralona cave, all three stages of the stone age are represented in Greece, for example in the Franchthi Cave. Neolithic settlements in Greece, dating from the 7th millennium BC, are the oldest in Europe by several centuries and these civilizations possessed writing, the Minoans writing in an undeciphered script known as Linear A, and the Mycenaeans in Linear B, an early form of Greek. The Mycenaeans gradually absorbed the Minoans, but collapsed violently around 1200 BC and this ushered in a period known as the Greek Dark Ages, from which written records are absent. The end of the Dark Ages is traditionally dated to 776 BC, the Iliad and the Odyssey, the foundational texts of Western literature, are believed to have been composed by Homer in the 7th or 8th centuries BC. With the end of the Dark Ages, there emerged various kingdoms and city-states across the Greek peninsula, in 508 BC, Cleisthenes instituted the worlds first democratic system of government in Athens

Mountain range
–
A mountain range is a geographic area containing numerous geologically related mountains. A mountain system or system of ranges, sometimes is used to combine several geological features that are geographically related. Mountain ranges are usually segmented by highlands or mountain passes and valleys, individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, most geologically young mountain ranges on the Earths land surface are associated with either the Pacific Ring of Fire or the Alpide Belt. The Andes is 7,000 kilometres long and is considered the worlds longest mountain system. The Alpide belt includes Indonesia and southeast Asia, through the Himalaya, the belt also includes other European and Asian mountain ranges. The Himalayas contain the highest mountains in the world, including Mount Everest, mountain ranges outside of these two systems include the Arctic Cordillera, the Urals, the Appalachians, the Scandinavian Mountains, the Altai Mountains and the Hijaz Mountains. If the definition of a range is stretched to include underwater mountains. The mountain systems of the earth are characterized by a tree structure, the sub-range relationship is often expressed as a parent-child relationship. For example, the White Mountains of New Hampshire and the Blue Ridge Mountains are sub-ranges of the Appalachian Mountains, equivalently, the Appalachians are the parent of the White Mountains and Blue Ridge Mountains, and the White Mountains and the Blue Ridge Mountains are children of the Appalachians. The position of mountains influences climate, such as rain or snow, when air masses move up and over mountains, the air cools producing orographic precipitation. As the air descends on the side, it warms again and is drier. Often, a shadow will affect the leeward side of a range. Mountain ranges are constantly subjected to forces which work to tear them down. Erosion is at work while the mountains are being uplifted and long after until the mountains are reduced to low hills, rivers are traditionally believed to be the principle erosive factor on mountain ranges, with their ability of bedrock incision and sediment transport. The rugged topography of a range is the product of erosion. The basins adjacent to a mountain range are filled with sediments which are buried and turned into sedimentary rock. The early Cenozoic uplift of the Rocky Mountains of Colorado provides an example and this mass of rock was removed as the range was actively undergoing uplift

Pindus
–
The Pindus mountain range is located in northern Greece and southern Albania. It is roughly 160 km long, with an elevation of 2,637 m. Because it runs along the border of Thessaly and Epirus, the Pindus range is called the spine of Greece. The mountain range stretches from near the Greek-Albanian borders in Northern Epirus, entering the Epirus region, geologically it constitutes an extension of the Dinaric Alps, which dominate the western region of the Balkan Peninsula. This vast complex of mountains, peaks, plateaus, valleys and its length reaches almost 230 kilometers and its largest width is 70 kilometers. Historically, the name Pindos refers to the territory that separates the greater Epirus region from the regions of Macedonia. P. Sustal says that, according to John Tzetzes, the Pindos range was called Metzovon at the time. We cannot be sure how valid this testimony is, but it indicates a popular name given to the mountain range. When Anastasios Gordios translated to a conversational language the initial praise to St. ”The identification of the name Metsovo with the Pindos mountain range is reproduced in a French encyclopedia of 1756. Furthermore, a series of sources refer to Pindos as the “mountains of Metsovo. ”Evidently, the word Pindos is part of the legacy, while the folk name for the mountain range from medieval times up to the 19th century was either “Metsovo” or “the mountains of Metsovo. ”Most probably this name did not include the whole range as it is meant today. It is further noteworthy that this coincides with the mountainous region which the ancient Greeks used to call Pindos. Some mountains in Southern Greece are also considered part of the extended Pindos range and its highest peak is on Mount Smolikas at an altitude of 2,637 meters. There are many villages in the Pindus, one of them being Samarina, many of the villages such as Perivoli and Smixi include communities of Aromanians, originally shepherds and farmers. In the last decades, a number of villages, such as Metsovo, the Egnatia Odos highway serves the region and connects it with the rest of Greece. Besides the imposing mountainous terrain of the range, two of the most magnificent gorges in Europe are located in the area, the Vikos Gorge, together with the mountain valley of Valia Kalda they have been declared protected regionsand constitute the National Park of Northern Pindos. Furthermore, many settlements with long history and unique architecture are located throughout the range. The Pindus ecoregion covers a range of elevations and habitats. A mixed broadleaf forest zone dominates the valleys and canyons of the middle, large breeding colonies of herons, spoonbills, egrets, and pelicans fish the cool waters of the mountain lakes of the Pindus Mountain Conifer and Broadleaf Mixed Forests ecoregion
