Understanding Chile’s geographical regions
Post available in: English
Chile may have “crazy” geography, but it is also a land of unparalleled beauty, with an incredible variety that has fascinated visitors since the Spanish conquest. Because Chile extends from a point about 625 kilometres north of the Tropic of Capricorn to a point hardly more than 1,400 kilometres north of the Antarctic Circle, within its territory can be found a broad selection of the earth’s climates. For this reason, it is possible to speak of several Chiles geographically. Geographers usually divide the country into five regions: the far north, the near north, central Chile, the south, and the far south. Each has its own characteristic vegetation, fauna, and climate, and, despite the omnipresence of both the Andes and the Pacific, its distinct topography.
The Far North
The far north (Norte Grande) extends from the Peruvian border to about 27° south latitude, a line roughly paralleled by the Río Copiapó, is extremely arid. It contains the Atacama Desert, one of the driest areas in the world; in certain sections, this desert does not register any rainfall. Average monthly temperatures range at sea level between about 20.5° C during the summer and about 14° C during the winter. Most of the population lives in the coastal area, where the temperatures are more moderate and the humidity higher. Contrary to the image of monochrome barrenness that most people associate with deserts, the landscape is spectacular, with its crisscrossing hills and mountains of all shapes and sizes, each with a unique colour and hue depending on its mineral composition, its distance from the observer, and the time of day.
In the far north, the land generally rises vertically from the ocean, sometimes to elevations well over 1,000 meters. The Cordillera Domeyko in the north runs along the coast parallel to the Andes. This topography generates coastal microclimates because the fog that frequently forms over the cold ocean waters and any low clouds is trapped by the high bluffs. This airborne moisture condenses in the spines and leaves of the vegetation, droplets that fall to the ground and irrigate the plants’ roots. Beyond the coastal bluffs, there is an area of rolling hills encompassing the driest desert land; this area ends to the east with the Andes towering over it. The edges of the desert in some sections have subterranean aquifers that have permitted the development of forests made mainly of tamarugos, spiny trees native to the area that grow to a height of about twenty-five meters. Most of those forests were cut down to fuel the fires of the many foundries established since colonial times to exploit the abundant deposits of copper, silver, and nitrate in the area. The result was the creation of even drier surface conditions.
The far north is the only part of the country in which there is a large section of the Andean (plateau). The area receives considerable rainfall during the summer months in what is commonly known as the “Bolivian winter,” forming shallow lakes of mostly saline waters that are home to several bird species, including the Chilean flamingo. Some of the water from the plateau trickles down the Andes in the form of narrow rivers, many of which form oases before being lost to evaporation or absorption into the desert sands, salt beds, and aquifers. However, some rivers do manage to reach into the Pacific, including the Río Loa, whose U-shaped course across the desert makes it Chile’s longest river. The water rights for one of the rivers, the Río Lauca, remain a source of dispute between Bolivia and Chile. These narrow rivers have carved fertile valleys in which exuberant vegetation creates a stark contrast to the bone-dry hills. In such areas, roads usually are built halfway up the arid elevations to maximize the intensive agricultural use of the irrigated land. They offer spectacular panoramic vistas and the harrowing experience of driving along the edges of cliffs.
In the far north, the fruits that grow well in the arid tropics thrive, and all kinds of vegetables can be grown year-round. However, the region’s main economic foundation is its great mineral wealth. For instance, Chuquicamata, the world’s largest open-pit copper mine, is located far north. Since the early 1970s, the fishing industry has also developed enormously in the main ports of the area, most notably Iquique and Antofagasta.
The Near North
The near north (Norte Chico) extends from the Río Copiapó to about 32° south latitude, or just north of Santiago. It is a semiarid region whose central area receives an average of twenty-five millimetres of rain during each of the four winter months, with trace amounts the rest of the year. The near north is also subject to droughts. The temperatures are moderate, with an average of 18.5° C during the summer and about 12° C during the winter at sea level. The winter rains and the melting snow that accumulates in the Andes produce rivers whose flow varies with the seasons but which carry water year-round. Their deep, transverse valleys provide broad areas for cattle raising and, most important, fruit growing, an activity that has developed dramatically since the mid-1970s.
As in the far north, the coastal areas of the near north have a distinct microclimate. In those sections where the airborne moisture of the sea is trapped by high bluffs overlooking the ocean, temperate rain forests develop as the vegetation precipitates the vapour in the form of misty rain. Because the river valleys provide breaks in the coastal elevations, maritime moisture can penetrate inland and further decrease the generally arid climate in those valleys. The higher elevations in the interior sections are covered with shrubs and cacti of various kinds.
Central Chile (Chile Central), home to most of the population, includes the three most significant metropolitan areas– Santiago, Valparaíso, and Concepción. It extends from about 32° south latitude to about 38° south latitude. The climate is of the temperate Mediterranean type, with the amount of rainfall increasing considerably and progressively from north to south. In the Santiago area, the average monthly temperatures are about 19.5° C in the summer months of January and February and 7.5° C in the winter months of June and July. The average monthly precipitation is no more than a trace in January and February and 69.7 millimetres in June and July. By contrast, in Concepción, the average monthly temperatures are somewhat lower in the summer at 17.6° C but higher in the winter at 9.3° C, and the amount of rain is much greater. In the summer, Concepción receives an average of twenty millimetres of rain per month; in June and July, the city is pounded by an average of 253 millimetres per month. The numerous rivers greatly increase their flow due to the winter rains and the spring melting of the Andean snow, and they contract considerably in the summer. The abundant snow in the Andes and relatively moderate winter temperatures create excellent Alpine skiing conditions.
The topography of central Chile includes a coastal range of mountains parallel to the Andes. Lying between the two mountain ranges is the so-called Central Valley, which contains some of the richest agricultural lands in the country, especially in its northern portion. The area just north and south of Santiago is a large producer of fruits, including the grapes from which the best Chilean wines are made. Exports of fresh fruit began to rise dramatically in the mid-1970s because Chilean growers could reach markets in the Northern Hemisphere during that part of the world’s winter. Most of these exports, such as grapes, apples, and peaches, go by refrigerator ships, but some, such as berries, go by air freight.
The southern portion of central Chile contains a mixture of some excellent agricultural lands, many of which were covered originally with old-growth forests. They were cleared for agriculture but were soon exhausted of their organic matter and left to erode. Large tracts of this worn-out land on hilly terrain have been reforested for lumber, especially for the cellulose and paper industries. New investments during the 1980s in these industries transformed the region’s rural economy. The pre-Andean highlands and some of the taller and more massive mountains in the coastal range (principally the Cordillera de Nahuelbuta) still contain large tracts of old-growth forests of remarkable beauty, which have been set aside as national parks. Between the coastal mountains and the ocean, many areas of central Chile contain stretches of land lower than the Central Valley and are generally quite flat. The longest beaches can be found in such sections.
Although many lovely lakes can be found in the Andean and coastal regions of central Chile, the south (Sur de Chile) is the country’s most lacustrine area. Southern Chile stretches from below the Río Bío-Bío at about 38° south latitude to below Isla de Chiloé at about 43.4° south latitude. In this lake district of Chile, the valley between the Andes and the coastal range is closer to sea level, and the hundreds of rivers that descend from the Andes form quite large lakes as they reach the lower elevations. They drain into the ocean through other rivers, some of which (principally the Río Calle Calle, which flows by the city of Valdivia) are the only ones in the country that are navigable for any stretch. The Central Valley’s southernmost portion is submerged in the ocean and forms the Golfo de Ancud. Isla de Chiloé, with its rolling hills, is the last significant elevation of the coastal range of mountains.
The south is one of the rainiest areas in the world. One of the wettest spots in the region is Valdivia, with an annual rainfall of 2,535.4 millimetres. The summer months of January and February are the driest, with monthly average precipitation of sixty-seven millimetres. On average, the winter months of June and July each produce a deluge of 410.6 millimetres. Temperatures in the area are moderate. In Valdivia, the summer months average 16.7° C, whereas the winter months average 7.9° C.
The lakes in this region are remarkably beautiful. The snow-covered Andes form a constant backdrop to vistas of clear blue or even turquoise waters, as at Lago Todos los Santos. The rivers that descend from the Andes rush over volcanic rocks, forming numerous white-water sections and waterfalls. The vegetation, including many ferns in the shady areas, is a lush green. Some sections still consist of old-growth forests, and in all seasons, but in the spring and summer, there are plenty of wildflowers and flowering trees. The pastures in the northernmost section, around Osorno, are well suited for raising cattle; milk, cheese, and butter are important products of that area. All kinds of berries grow in the area, some of which are exported, and freshwater farming of various species of trout and salmon has developed, with cultivators taking advantage of the abundant supply of clear running water. The lumber industry is also important. Several tourists, mainly Chileans and Argentines, visit the area during the summer.
Many of Chile’s distinctive animal species have been decimated as they have been pushed farther and farther into the remaining wilderness areas by the human occupation of the land. This is the case with the huemul, a large deer, and the Chilean condor, the largest bird of its kind; both animals are on the national coat of arms. The remaining Chilean pumas, bigger than their California cousins, have been driven to isolated national parks in the south by farmers who continue to hunt them because they occasionally kill sheep and goats.
The Far South
The Andes and the South Pacific meet in the far south (Chile Austral), which extends from between 43° south latitude and 44° south latitude to Cape Horn. The continental coastline features numerous inlets and fjords, from which the mountains seem to rise straight up to great elevations; this is, for example, the case with the Cerro Macá (2,960 meters) near Puerto Aisén. The rest of the land consists of thousands of islands forming numerous archipelagos interwoven with sometimes-narrow channels, which provide the main navigation routes.
In the northern part of the far south, there is still plenty of rainfall. For instance, Puerto Aisén, at 45°24′ south latitude, receives 2,973.3 millimetres of rain annually. However, unlike in Valdivia, the rain falls more or less evenly throughout the year in Puerto Aisén. The summer months average 206.1 millimeters, whereas the winter months average 300 millimeters. The sea-level temperatures in Puerto Aisén average 13.6° C in summer and 4.7° C in winter. Although the area generally is chilly and wet, the combination of channels, fjords, snowcapped mountains, and islands of all shapes and sizes within such a narrow space makes for breathtaking views. The area is still heavily forested, although some of the native species of trees that grow in the central and southern parts of the country have given way to others better adapted to a generally colder climate.
The southern part of the far south includes the city of Punta Arenas, which, with about 125,000 inhabitants, is the southernmost city of any appreciable size in the world. It receives much less precipitation; its annual total is only 438.5 millimetres, or a little more than Valdivia gets in June alone. This precipitation is distributed more or less evenly throughout the year, with the two main summer months receiving a monthly average of thirty-one millimeters and the winter months 38.9 millimeters, some of it in the form of snow. Temperatures are colder than in the rest of the country. The summer months average 11.1° C, and the winter averages 2.5° C. The constant South Pacific Ocean wind makes the air feel much colder.
The far south contains large expanses of pastures that are best suited for raising sheep. The area’s other main economic activity is oil and natural gas extraction from the areas around the Strait of Magellan. This strait is one of the world’s important sea lanes because it unites the Atlantic and Pacific oceans through a channel that avoids the rough open waters off Cape Horn. The channel is perilous, however, and Chilean pilots guide all vessels through it.
