La Rinconada is a town in the Peruvian Andes located near a gold mine. At 5,100 m above sea level, it is the highest permanent settlement in the world. Between 2001 and 2009, the population increased to 30,000 people from just a small gold prospector camp because the price of gold rose 235% in the same time.
The town is located in the Ananea District, San Antonio de Putina Province. It lies at a height of 5,130 m (16,830 feet) above sea level. It sits at the foot of La Bella Durmiente, "The Sleeping Beauty" glacier. Some successful miners in La Rinconada have homes in Juliaca which has municipal services and is at a lower altitude.
Located high in the Andes, La Rinconada has an alpine / tundra climate (ET, according to the Köppen climate classification), with no month having average temperatures even close to the 10°C threshold that would permit tree growth and a subtropical highland classification for the city. Far above the tree line, La Rinconada is unique in its high elevation and population, with the highest city of comparable population (Cerro de Pasco) being located over 700m closer to sea level.
Owing to the extreme elevation of the town, climatic conditions more closely resemble that of the west coast of Greenland than somewhere located only 14° from the equator. The town has rainy summers and dry winters with a large diurnal variation seeing cool to cold days and freezing night time temperatures throughout the year, with common snowfalls. The average annual temperature in La Rinconada is 1.2 °C and the average annual rainfall is 707 mm.
The economy is mainly based on the production of gold from nearby gold mines, many artisanal.
Many miners work at the gold mine owned by Corporación Ananea. Under the cachorreo system they work for 30 days without payment. On the 31st day they are allowed to take with them as much ore as they can carry on their shoulders. Whether the ore contains any gold or not is a matter of luck. Pocketing of nuggets or promising chunks of rich ore is tolerated. Women are banned from the mines, but pallaqueras can be seen working though rock on the mine dumps.
Inca Manco Cápac International Airport is the nearest commercial airport; it is located in Juliaca.
The town lacks plumbing and sanitation systems. There is also significant contamination by mercury,[citation needed] due to the mining practices. Local miners refine the ore by grinding and treating it with mercury and pressing the mass through a cloth to filter it. The resulting amalgam is heated, to remove the mercury.

El Alto (Spanish for "The Heights") is a municipality and the second-largest city in Bolivia, located adjacent to La Paz in Pedro Domingo Murillo Province on the Altiplano highlands. El Alto is today one of Bolivia's fastest-growing urban centers, with a population of 974,754 in 2011. El Alto is the highest major metropolis in the world, with an average elevation of 4,150 m (13,615 ft).
The El Alto-La Paz metropolitan area, formed by the cities of El Alto, La Paz, and Viacha, constitutes the most populous urban area of Bolivia, with a population of 2.3 million inhabitants (greater than the metropolitan area of the country's largest city of Santa Cruz de la Sierra).
The dry and inclement plain above La Paz was uninhabited until 1903 when the newly built railways from Lake Titicaca and Arica reached the rim of the canyon, where the La Paz terminus, railyards and depots were built along with a settlement of railway workers (a spur line down into the canyon opened in 1905). In 1925, the airfield was built as base for the new air force, which attracted additional settlement. In 1939, El Alto's first elementary school opened. El Alto started to grow tremendously in the 1950s when the settlement was connected to La Paz's water supply (before this, all water had to be transported from La Paz in tanker vehicles) and building land in the canyon became more and more scarce and expensive. In an administrative reform in March 1985, the district of El Alto and surroundings was politically separated from the City of La Paz (this date is officially referred to and celebrated as the city's "founding day"). In 1987, El Alto was formally incorporated as a city. In 1994, the city became the seat of the Roman Catholic Diocese of El Alto.
El Alto, known for its teeming streets and traffic, broke gender barriers by hiring "cholitas" in December 2013. These Aymara women dress in traditional, multi-layered Andean skirts and brightly embroidered vests, and work as traffic cops to bring order to its road chaos. In recent years, Bolivia’s cholitas have been breaking social barriers, conducting television programs, working in offices, holding public posts, and participating in native fashion shows and beauty contests.
El Alto can also mean "The Halt" in Spanish, and a story persists[citation needed] that the conquistador Alonso de Mendoza stopped in El Alto on 23 October 1548 on his way to founding the city of La Paz.
El Alto is the largest city in Latin America with a mostly Amerindian population. About 76% of its inhabitants are Aymara, 9% are Quechua, 15% are Mestizo (descendants of Amerindian and White Europeans), and less than 0.1% are Criollos (White). El Alto was once known as La Paz's bedroom community, though recent growth of commerce and industry has led some local authorities to claim the title of "Bolivia's Economic Capital." With this industrial growth, there is concern about water pollution by businesses, including tanneries and slaughterhouse, for the city and communities downstream. Rapid population growth means the city struggles to bring potable water and sewer service to parts of the population, especially on the fringes of the expanding urban area. Much of the cities roads are unpaved and most citizens do not have access to running water, sewerage, electricity or garbage collection for their homes.
The city contains La Paz’s El Alto International Airport. El Alto is one of the highest major cities in the world, up to 4,150 meters (13,615 feet) above mean sea level. It has a cold climate, with the highest average monthly maximum temperature being 17 °C (63 °F) in November. It is one of the fastest-growing cities in Bolivia, due to a trend in migration from Bolivia’s rural areas to the La Paz region that started with the rural reform of 1952 and increased in the last 10 years. Some migrants say the difficulty of growing crops in the countryside drove them to move to the city.
The Köppen-Geiger climate classification system classifies El Alto's climate as a rare cool summer variety of a subtropical highland climate (Cwc).
Museo de Arte Antonio Paredes Candia opened in 2002. From 2003, access from La Paz to the international airport, as well to oil and gas supplies, has been frequently blocked by protesting social leaders and some of the most powerful players in the politics of Bolivia. El Alto remains one of the major centers of the Bolivian gas conflict.
There is a large open-air market.

https://en.m.wikipedia.org/wiki/Burgos
Burgos (Spanish pronunciation: [ˈbuɾɣos], UK: /ˈbʊərɡɒs/, US: /ˈbʊərɡoʊs/) is a city in northern Spain and the historic capital of Castile. It is situated on the confluence of the Arlanzón river tributaries, at the edge of the Iberian central plateau. It has about 180,000 inhabitants in the actual city and another 20,000 in the metropolitan area. It is the capital of the province of Burgos, in the autonomous community of Castile and León. Burgos was once the capital of the Crown of Castile, and the Burgos Laws or Leyes de Burgos which first governed the behaviour of Spaniards towards the natives of the Americas were promulgated here in 1512.
It has many historic landmarks, of particular importance; the Cathedral of Burgos (declared World Heritage Site by UNESCO in 1984), seat of the Metropolitan Roman Catholic Archdiocese of Burgos, the Las Huelgas Reales Monastery and Miraflores Charterhouse. A large number of churches, palaces and other buildings from the medieval age remain. The city is surrounded by the Fuentes Blancas and the Paseo de la Isla parks.
Castilian nobleman, military leader and diplomat El Cid Campeador is a significant historical figure in the city, as he was born a couple of kilometres north of Burgos and was raised and educated here.
The city forms the principal crossroad of northern Spain along the Camino de Santiago, which runs parallel to the River Arlanzón.
It has a well-developed transportation system, forming the main communication node in northern Spain. In 2008, the international Burgos Airport started to offer commercial flights. Furthermore, AVE high speed trains are planned to start service in the near future, stopping at the newly-built Rosa de Lima train station.
The Museum of Human Evolution was opened in 2010, unique in its kind across the world and projected to become one of the top 10 most-visited museums in Spain. The museum features the first Europeans, which lived in this area 800,000 years ago.
Burgos was selected as the Spanish Gastronomy Capital of 2013.
At an elevation of 856 metres (2,808 ft), the city of Burgos lies in the transition zone between a Warm-summer Mediterranean climate (Köppen Csb) and an Oceanic climate (Köppen Cfb), with some continental influence resulting from its distance from the sea and higher altitude. Burgos' climate features chilly and windy winters, due to altitude and an inland location, which always include snow and temperatures below freezing. Temperature ranges can be extreme and Burgos is drier than Spain's coastal regions, although there is year-round precipitation. Average annual precipitation is 546 mm (21.5 in) and the average annual relative humidity is 72%. In winter, temperatures very often (almost every day) drop below freezing, often reaching temperatures as low as −10 °C (14 °F), and snowfalls are common, while the summer months see average high temperatures of 27.5 °C (81.5 °F).

https://en.m.wikipedia.org/wiki/Ávila,_Spain
Ávila (Spanish pronunciation: [ˈaβila]; Latin: Abula) is a Spanish town located in the autonomous community of Castile and León, and is the capital of the Province of Ávila.
It is sometimes called the Town of Stones and Saints, and it claims that it is one of the towns with the highest number of Romanesque and Gothic churches per capita in Spain. It has complete and prominent medieval town walls, built in the Romanesque style. The town is also known as Ávila de los Caballeros, Ávila del Rey and Ávila de los Leales (Ávila of the Knights, the King and the Loyalists), each of these epithets being present in the town standard.
Orson Welles once named Ávila as the place in which he would most desire to live, calling it a "strange, tragic place", while writer José Martínez Ruiz, in his book El alma castellana (The Castilian Soul), described it as "perhaps the most 16th-century town in Spain".
It was declared a UNESCO World Heritage Site in 1985.
Ávila's position results in a temperate Mediterranean climate (Csb, according to the Köppen climate classification), with warm summers and chilly winters with snowfalls, bordering on a cold semi-arid climate (BSk). The hottest month, July, has an average temperature of 20.6 °C (69 °F), and the coldest month, January, has an average of 3.0 °C (37 °F). The average annual precipitation is 416 mm (16.38 in).[3] Annual rainfall is low compared to surrounding areas, implying that it lies in a rain shadow. The Adaja is dry for several months of the year and the town has historically had water supply problems. Ávila is the provincial capital city in Spain with the coldest winter low temperatures, which is caused for its altitude, as the city has an average elevation of 1,132 metres (3,714 ft) above sea level.

https://en.m.wikipedia.org/wiki/Davos
Davos (German pronunciation [daˈfoːs] or [daˈvoːs]; Romansh: About this sound Tavau (help·info), archaic Italian: Tavate) is an Alpine town, and a municipality in the Prättigau/Davos Region in the canton of Graubünden, Switzerland. It has a permanent population of 11,060 (2016). Davos is located on the river Landwasser, in the Rhaetian Alps, between the Plessur and Albula Range. At 1,560 m (5,120 ft), it is described as "the highest town in the Alps".
The former Alpine resort village consists of two parts: Davos Dorf (lit.: "village") to the northeast towards Klosters and further down through the Prättigau to Landquart, and Davos Platz (lit.: "place") to the southwest, which opens into the valley of the Landwasser (lit.: "country water") and eventually leads to Filisur. During summer season the Flüela Pass leads south-east into the Lower Engadine.
Davos is host to the World Economic Forum (WEF), an annual meeting of global political and business elites (often referred to simply as Davos) and the home of one of Switzerland's biggest ski resorts. At the end of every year it serves as the site of the annual Spengler Cup ice hockey tournament, hosted by the HC Davos local hockey team.
Davos has a subarctic climate (Köppen Dfc) with an average of 124.7 days of precipitation per year and on average receives 1,022 mm (40.2 in) of precipitation.
The wettest month is August during which time Davos receives an average of 148 mm (5.8 in) of precipitation. During this month there is precipitation for an average of 13.5 days. The month with the most days of precipitation is June, with an average of 13.6, but with only 126 mm (5.0 in) of precipitation. The driest month of the year is April with an average of 56 mm (2.2 in) of precipitation over 9.6 days, of which 50.9 cm (20.0 in) in 8.5 days are snowfall.

More Altitude more convex noses
At least it's very true for peruvians
And maybe a stockier torso
And yes... For sure darker skin as sun radiation is higher in elevated altitude

And what if this is because we observe them from downwards?
http://www.sciencemag.org/news/2018/05/study-short-peruvians-reveals-new-gene-major-impact-height
evolution has favored short stature and perhaps thick skin among Peruvians. Many live at high altitudes, and animal studies show that species living at such elevations tend to be smaller, an apparent evolutionary adaptation to the scarcity of food in those places. Thick skin might also protect the body from the strong ultraviolet light at high altitudes
https://en.m.wikipedia.org/wiki/High-altitude_adaptation_in_humans
High-altitude adaptation in humans is an instance of evolutionary modification in certain human populations, including those of Tibet in Asia, the Andes of the Americas, and Ethiopia in Africa, who have acquired the ability to survive at extremely high altitudes. This adaptation means irreversible, long-term physiological responses to high-altitude environments, associated with heritable behavioural and genetic changes.
While the rest of the human population would suffer serious health consequences, the indigenous inhabitants of these regions thrive well in the highest parts of the world. These people have undergone extensive physiological and genetic changes, particularly in the regulatory systems of oxygen respiration and blood circulation, when compared to the general lowland population.
This special adaptation is now recognised as an example of natural selection in action. The adaptation account of the Tibetans has become the fastest case of human evolution in the scientific record, as it is estimated to have occurred in less than 3,000 years.
Modern humans dispersed from Africa less than 100,000 years ago, and eventually colonized the rest of the world, including the harshest environments of extreme cold and high mountains. The abundance of oxygen in the atmosphere is inversely related to altitude from the sea level; hence, the highest mountain ranges of the world are considered unsuitable for human habitation.
Nevertheless, around 140 million people, just under 2% of the world's human population, live permanently at high altitudes, that is, at heights above 2,500 metres (8,200 ft) in South America, East Africa, and South Asia. These populations have done so for millennia without apparent complications.[9] The overwhelming majority, over 98% of humans from other parts of the world, normally suffer symptoms of altitude sickness in these regions, often resulting in life-threatening trauma and even death.
Studies on the detail biological mechanism have revealed that adaptation of the Tibetans, Andeans and Ethiopians is indeed an observable instance of the process of natural selection in acting on favourable characters such as enhanced respiratory mechanisms in humans.
Humans are naturally adapted to lowland environment where oxygen is abundant. When people from the general lowlands go to altitudes above 2,500 metres (8,200 ft), with atmospheric pressure 74% of normal they experience mountain sickness, which is a type of hypoxia, a clinical syndrome of severe lack of oxygen. Complications include fatigue, dizziness, breathlessness, headaches, insomnia, malaise, nausea, vomiting, body pain, loss of appetite, ear-ringing, blistering and purpling of the hands and feet, and dilated veins.
The sickness is compounded by related symptoms such as cerebral oedema (swelling of brain) and pulmonary oedema (fluid accumulation in lungs). For several days, they breathe excessively and burn extra energy even when the body is relaxed. The heart rate then gradually decreases. Hypoxia, in fact, is one of the principal causes of death among mountaineers. In women, pregnancy can be severely affected, such as development of high blood pressure, called preeclampsia, which causes premature labour, low birth weight of babies, and often complicated with profuse bleeding, seizures, and death of the mother.
More than 140 million people worldwide are estimated to live at an elevation higher than 2,500 metres (8,200 ft) above sea level, of which 13 million are in Ethiopia, 1.7 million in Tibet (total of 78 million in Asia), 35 million in the South American Andes, and 0.3 million in Colorado Rocky Mountains. Certain natives of Tibet, Ethiopia, and the Andes have been living at these high altitudes for generations and are protected from hypoxia as a consequence of genetic adaptation. It is estimated that at 4,000 metres (13,000 ft), every lungful of air only has 60% of the oxygen molecules that people at sea level have. At elevations above 7,600 metres (24,900 ft), lack of oxygen becomes seriously lethal. That is, these highlanders are constantly exposed to an intolerably low oxygen environment, yet they live without any debilitating problems. Basically, the shared adaptation is the ability to maintain relatively low levels of haemoglobin, which is the chemical complex for transporting oxygen in the blood. One of the best documented effects of high altitude is a progressive reduction in birth weight. It has been known that women of long-resident high-altitude population are not affected. These women are known to give birth to heavier-weight infants than women of lowland inhabitants. This is particularly true among Tibetan babies, whose average birth weight is 294-650 (~470) g heavier than the surrounding Chinese population; and their blood-oxygen level is considerably higher.
The first scientific investigations of high-altitude adaptation was done by A. Roberto Frisancho of the University of Michigan in the late 1960s among the Quechua people of Peru. However, the best scientific studies were started among the Tibetans in the early 1980s by an anthropologist Cynthia Beall of the Case Western Reserve University.
Tibetans
Scientists started to notice the extraordinary physical performance of Tibetans since the beginning of Himalayan climbing era in the early 20th century. The hypothesis of a possible evolutionary genetic adaptation makes sense.[27] The Tibetan plateau has an average elevation of 4,000 metres (13,000 ft) above sea level, and covering more than 2.5 million km, it is the highest and largest plateau in the world. In 1990, it was estimated that 4,594,188 Tibetans live on the plateau, with 53% living at an altitude over 3,500 metres (11,500 ft). Fairly large numbers (about 600,000) live at an altitude exceeding 4,500 metres (14,800 ft) in the Chantong-Qingnan area.[28] Where the Tibetan highlanders live, the oxygen level is only about 60% of that at sea level. The Tibetans, who have been living in this region for 3,000 years, do not exhibit the elevated haemoglobin concentrations to cope with oxygen deficiency as observed in other populations who have moved temporarily or permanently at high altitudes. Instead, the Tibetans inhale more air with each breath and breathe more rapidly than either sea-level populations or Andeans. Tibetans have better oxygenation at birth, enlarged lung volumes throughout life, and a higher capacity for exercise. They show a sustained increase in cerebral blood flow, lower haemoglobin concentration, and less susceptibility to chronic mountain sickness than other populations, due to their longer history of high-altitude habitation.[29][30]
General people can develop short-term tolerance with careful physical preparation and systematic monitoring of movements, but the biological changes are quite temporary and reversible when they return to lowlands.[31] Moreover, unlike lowland people who only experience increased breathing for a few days after entering high altitudes, Tibetans retain this rapid breathing and elevated lung-capacity throughout their lifetime.[32] This enables them to inhale larger amounts of air per unit of time to compensate for low oxygen levels. In addition, they have high levels (mostly double) of nitric oxide in their blood, when compared to lowlanders, and this probably helps their blood vessels dilate for enhanced blood circulation.[33] Further, their haemoglobin level is not significantly different (average 15.6 g/dl in males and 14.2 g/dl in females),[34] from those of people living at low altitude. (Normally, mountaineers experience >2 g/dl increase in Hb level at Mt. Everest base camp in two weeks.[35]) In this way they are able to evade both the effects of hypoxia and mountain sickness throughout life. Even when they climbed the highest summits like Mt. Everest, they showed regular oxygen uptake, greater ventilation, more brisk hypoxic ventilatory responses, larger lung volumes, greater diffusing capacities, constant body weight and a better quality of sleep, compared to people from the lowland.[36]
Andeans
In contrast to the Tibetans, the Andean highlanders, who have been living at high-altitudes for no more than 11,000 years, show different pattern of haemoglobin adaptation. Their haemoglobin concentration is higher compared to those of lowlander population, which also happens to lowlanders moving to high altitude. When they spend some weeks in the lowland their haemoglobin drops to average of other people. This shows only temporary and reversible acclimatisation. However, in contrast to lowland people, they do have increased oxygen level in their haemoglobin, that is, more oxygen per blood volume than other people. This confers an ability to carry more oxygen in each red blood cell, making a more effective transport of oxygen in their body, while their breathing is essentially at the same rate.[32] This enables them to overcome hypoxia and normally reproduce without risk of death for the mother or baby. The Andean highlanders are known from the 16th-century missionaries that their reproduction had always been normal, without any effect in the giving birth or the risk for early pregnancy loss, which are common to hypoxic stress.[37] They have developmentally acquired enlarged residual lung volume and its associated increase in alveolar area, which are supplemented with increased tissue thickness and moderate increase in red blood cells. Though the physical growth in body size is delayed, growth in lung volumes is accelerated.[38] An incomplete adaptation such as elevated haemoglobin levels still leaves them at risk for mountain sickness with old age.
Among the Quechua people of the Altiplano, there is a significant variation in NOS3 (the gene encoding endothelial nitric oxide synthase, eNOS), which is associated with higher levels of nitric oxide in high altitude.[39] Nuñoa children of Quechua ancestry exhibit higher blood-oxygen content (91.3) and lower heart rate (84.8) than their counterpart school children of different ethnicity, who have an average of 89.9 blood-oxygen and 88-91 heart rate.[40] High-altitude born and bred females of Quechua origins have comparatively enlarged lung volume for increased respiration.[41]
Blood profile comparisons show that among the Andeans, Aymaran highlanders are better adapted to highlands than the Quechuas.[42][43] Among the Bolivian Aymara people, the resting ventilation and hypoxic ventilatory response were quite low (roughly 1.5 times lower), in contrast to those of the Tibetans. The intrapopulation genetic variation was relatively less among the Aymara people.[44][45] Moreover, unlike the Tibetans, the blood haemoglobin level is quite normal among Aymarans, with an average of 19.2 g/dl for males and 17.8 g/dl for females.[34] Among the different native highlander populations, the underlying physiological responses to adaptation are quite different. For example, among four quantitative features, such as are resting ventilation, hypoxic ventilatory response, oxygen saturation, and haemoglobin concentration, the levels of variations are significantly different between the Tibetans and the Aymaras.[46] The Andeans, in general are the most poorly adapted, as particularly shown by their frequent mountain sickness and loss of adaptative characters when they move to lowlands.[47]
Ethiopians
The peoples of the Ethiopian highlands also live at extremely high altitudes, around 3,000 metres (9,800 ft) to 3,500 metres (11,500 ft). Highland Ethiopians exhibit elevated haemoglobin levels, like Andeans and lowlander peoples at high altitudes, but do not exhibit the Andean’s increased in oxygen-content of haemoglobin.[48] Among healthy individuals, the average haemoglobin concentrations are 15.9 and 15.0 g/dl for males and females respectively (which is lower than normal, almost similar to the Tibetans), and an average oxygen saturation of haemoglobin is 95.3% (which is higher than average, like the Andeans).[49] Additionally, Ethiopian highlanders do not exhibit any significant change in blood circulation of the brain, which has been observed among the Peruvian highlanders (and attributed to their frequent altitude-related illnesses).[50] Yet, similar to the Andeans and Tibetans, the Ethiopian highlanders are immune to the extreme dangers posed by high-altitude environment, and their pattern of adaptation is definitely unique from that of other highland peoples.[22]

Jericho (/ˈdʒɛrɪkoʊ/; Hebrew: יְרִיחוֹ Yərīḥō; Arabic: أريحا Arīḥā [ʔaˈriːħaː] (About this sound listen)) is a city in the Palestinian Territories and is located near the Jordan River in the West Bank. It is the administrative seat of the Jericho Governorate, and is governed by the Fatah faction of the Palestinian National Authority. In 2007, it had a population of 18,346. The city was occupied by Jordan from 1949 to 1967, and has been held under Israeli occupation since 1967; administrative control was handed over to the Palestinian Authority in 1994. It is believed to be one of the oldest inhabited cities in the world and the city with the oldest known protective wall in the world. It was thought to have the oldest stone tower in the world as well, but excavations at Tell Qaramel in Syria have discovered stone towers that are even older.
Archaeologists have unearthed the remains of more than 20 successive settlements in Jericho, the first of which dates back 11,000 years (9000 BC), almost to the very beginning of the Holocene epoch of the Earth's history.
Copious springs in and around the city have attracted human habitation for thousands of years. Jericho is described in the Hebrew Bible as the "City of Palm Trees".
