Chile

Alberto de Agostini National Park is a protected area in southern Chile that includes the Cordillera Darwin mountain range, the final land-based stretch of the Andes before it becomes a chain of mountains appearing as small islands that sink into the Pacific Ocean.

Alerce Andino National Park is located in the Andes, in the Los Lagos Region of Chile. The centerpiece of this lush and mountainous protected area is the Alerce forests. The Alerce is a towering tree species native to the Andes Mountains that can live for over 4,000 years.

Alerce Costero National Park is a protected area in the Los Ríos Region of southern Chile. Situated within the Cordillera Pelada, a mountain range part of the more extensive Chilean Coastal Range, the National Park hosts a forest of endangered Patagonian cypress.

The Altiplano is a high plateau region in west-central South America where the Andes are the widest. The bulk of the Altiplano-Puna plateau lies in Bolivia, its northern parts lie in Peru, and its southern parts lie in Chile and Argentina. The Altiplano Basin is a sedimentary basin located on the plateau.

The Altiplano-Puna volcanic complex is a major caldera and volcanic field located in the southern Altiplano-Puna plateau in the central Andes, including parts of Argentina, Bolivia, and Chile. It includes two active geothermal areas: Tatio and Sol de Manana.

The Andean Patagonian Forest spreads over steep elevations along a thin strip on both sides of the Andes Mountains in southern South America. These temperate forests in southern Chile and Argentina are the southernmost forests on earth.

The Andean Volcanic Belt, along the South American coast, is segmented into four main volcanic zones. These volcanoes, along the backbone of the Andes, are part of the Ring of Fire, an area in the Pacific Ocean basin where earthquakes and eruptions occur due to the collision of tectonic plates.

The Andes Mountains are the longest continental mountain range in the world. They form a continuous highland along the western coast of South America. The Andean Region extends north-south from Caribbean Venezuela through the Atacama Desert to cold, windy, wet Cape Horn.

The Atacama Desert is located in northern Chile between Argentina on the west and the Pacific Ocean on the east. Sparsely populated and containing considerable mineral resources, the Atacama Desert is one of the driest places in the world.

The Atacama Plateau, also known as the Puna de Atacama, is an arid high plateau in the Andes of northwestern Argentina, extending into Chile. This cold, desolate Andean tableland can be defined as the southernmost portion of the Andean Altiplano.
