Santiago Metropolitan Region
Santiago Metropolitan Region is one of Chile's 16 first-order administrative divisions. It is the country's only landlocked administrative region and contains the nation's capital, Santiago. Most commercial and administrative centers are located in the region, including Chile's main international airport, Arturo Merino Benítez International Airport.
With an area of and population over seven million, it is Chile's most populated and most densely populated region. It is also the most developed subdivision in all of South America with a very high HDI of 0.908.
History
The region's history of European influence started in 1542, a few days after Santiago was founded. When the Santiago cabildo was built, its function was to supervise the entire territory. Later, with the creation of the cities of La Serena and Concepción and the creation of their respective cabildos, its territorial reach was reduced.On 30 August 1826, 8 provinces were created, with the Santiago Province being one of them, but it wasn't until 1980 that the Metropolitan Region was created.
Geography
Metropolitana is Chile's only landlocked region and lies in the Intermediate Depression valley between the Chilean Coast Range and the Andes Mountains. Cerro San Cristóbal dominates the sprawling Santiago cityscape at a height of above sea level with city suburbs steadily climbing the foothills of the Andes to the east. The Tupungato stratovolcano, measures on the Argentine border, is one of South America's highest peaks.The dominant drainage basin feeds into the Maipo River; its main tributaries are the Mapocho, Yeso and Colorado rivers.
Most of the region is made up of an extremely fertile, level prairie that the locals call la Depresión intermedia. The terrain is known for its low elevation in relation to sea level and for being surrounded by hills, as well as emergent so-called island hills, such as Santa Lucía, Blanco, and Renca, present today in the city of Santiago.
There is some occurrence of the endangered Chilean Wine Palm, Jubaea chilensis within the Santiago Province; this iconic tree of central Chile had a much larger range prehistorically, before the decimation of much of its habitat by the expanding human population.
The region mountainous parts of the region host various deposits of copper ore. To the north the mine of Los Bronces straddle the border with Valparaíso Region in the high Andes. Also in the high Andes but to the south along the border with O'Higgins Region lies the unexploited copper ore prospect of Catedral. To the west of the region at the foot of the Chilean Coastal Cordillera lies the mine Lo Aguirre which closed in 2000.
Climate
The climate of the Metropolitan Region is temperate Mediterranean cold, of the kind called continental. Precipitation is concentrated in the winter months, generally as snow over 900 m above sea level and, in colder years, over the city of Santiago. Winter tends to be cold with frequent frosts during which temperature drops below. The summer months are usually dry and hot. The Cordillera de la Costa acts as a climate screen and reduces marine influence, which makes the climate more continental. This situation becomes apparent when comparing precipitation from a coastal location such as Valparaíso with that of Santiago de Chile.The annual median precipitation reaches 367 mm on average. The annual median temperature comes out to, with a median high of and a median low of in urban areas. Rural areas tend to be colder, as temperature reaches in the coldest months
