Peru - February 12th, 2010

The mountains in this orthorectified image are part of the Cordillera Oriental (“eastern mountain range”) of the Andes in Peru. Crossing the lower left quadrant diagonally from left to right is the valley of the Urubamba River, which rises in the Andes to the south-east of Cuzco near the Puno Region border.

Several lakes can be seen near the river, including Laguna Langui Layo (by the center of the bottom edge) and Laguna Sibinacocha (center of left edge). The former is located at an altitude of 3883 meters (12740 feet), and the latter at 4950 meters, making it one of the highest large lakes in the world.

Cayambe (or Volcán Cayambe) is the name of a volcano located in the Cordillera Oriental, a branch of the Ecuadorian Andes. It is located in Pichincha province some 70 km (43 mi) northeast of Quito, in the upper left quadrant of this orthorectified image.

It is the third highest mountain in Ecuador. Cayambe, which has a permanent snow cap, is a Holocene compound volcano which has not erupted in historical times. At 4,690 m (15,387 ft) on its south slope is the highest point in the world crossed by the Equator and the only point on the Equator with snow cover. The volcano is located within the Cayambe-Coca Ecological Reserve.

Another volcano, Reventador, can be seen to the southeast of Cayambe, just about the center of the image. It is an active stratovolcano which lies in the eastern Andes of Ecuador. It lies in a remote area of the national park of the same name. The volcano’s main peak lies inside a U-shaped caldera which is open towards the Amazon basin to the east. Its lavas are andesitic.

Since 1541 it has erupted over 25 times, although its isolated location means that many of its eruptions have gone unreported. Its most recent eruption was in 2009, but the largest historical eruption occurred in 2002. During that eruption the plume from the volcano reached a height of 17 km and pyroclastic flows went up to 7 km from the cone.

Here, the white peaks of the Andes Mountains cut through Northern Colombia (left) and northwestern Venezuela (right) in South America. East of the mountains lies an area of extensive plains. To the north, the Gulf of Venezuela contains some greenish sediments.

With 2,800 kilometres (1,740 mi) of coastline, Venezuela is home to a wide variety of landscapes. The extreme northeastern extensions of the Andes reach into Venezuela’s northwest and continue along the northern Caribbean coast.

The country’s center is characterized by the llanos, extensive plains that stretch from the Colombian border in the far west to the Orinoco River delta in the east.

Colombia is dominated by the Andes mountains. Beyond the Colombian Massif (in the Southwest) these are divided into three branches known as cordilleras: the Cordillera Occidental, running adjacent to the Pacific coast; the Cordillera Central, running between the Cauca and Magdalena river valleys (to the west and east respectively); and the Cordillera Oriental, extending north east to the Guajira Peninsula.

East of the Andes lies the savanna of the Llanos, part of the Orinoco River basin, and, in the far south east, the jungle of the Amazon rainforest. Together these lowlands comprise over half Colombia’s territory, but they contain less than 3% of the population.

To the north the Caribbean coast, home to 20% of the population, generally consists of low-lying plains, but it also contains the Sierra Nevada de Santa Marta mountain range and the Guajira Desert.

By contrast the narrow and discontinuous Pacific coastal lowlands, backed by the Serranía de Baudó mountains, are covered in dense vegetation and sparsely populated.
