Andes Mountains Separating Altiplano and Gran Chaco, Bolivia

17.8S 64.8W

September 16th, 2012 Category: Fires, Lakes, Mountains, Salt Flats

Bolivia and Peru – August 31st, 2012

The ridges of the Andes Mountains mark the division between two starkly contrasting regions in Bolivia: the arid altiplanto (left) and the hot and semi-arid lowlands of the Gran Chaco (sometimes referred to as the Chaco Plain). Visible by the left edge are the bright white salt flats of the Salar de Uyuni and the greenish waters of Lake Poopó. Of note in the upper right corner is smoke from fires that have been affecting the country recently (click here for previous images).

Vegetation Index of Argentina Near Andes Mountains

30.7S 62.8W

February 25th, 2012 Category: Vegetation Index

Argentina - January 2nd, 2012

This FAPAR image shows the vegetation index of western-central Argentina, near the Andes Mountains. Visible near the center of the image is the Mar Chiquita, an endorheic salt lake located in the province of Córdoba, in central Argentina. It is the largest of the naturally occurring saline lakes in Argentina, and occupies the southern part of a large depression.

The vegetation index is generally good (green), with some intense areas of high photosynthetic activity (rusty red) visible near the foothills of the Andes. The mountains at higher altitudes, however, show a low index (yellow), and the photosynthetic activity around Mar Chiquita is also low.

Santiago de Chile West of Andes Mountains

Chile - January 9th, 2011

This orthorectified image shows the eastern part of Santiago, the capital city of Chile. The city lies in the center of the Santiago Basin, a large bowl-shaped valley consisting of a broad and fertile lands surrounded by mountains. The city has a varying elevation, with 400 m (1,312 ft) in the western areas and 540 m (1,772 ft) in the Plaza Baquedano.

It is flanked by the main chain of the Andes on the east and the Chilean Coastal Range on the west. On the north, it is bounded by the Cordón de Chacabuco, a mountain range of the Andes. During recent decades, urban growth has expanded the boundaries of the city to the east closer to the Andean Precordillera, as can be observed here. To the east stands the massive Ramon Sierra, a mountain chain formed in the foothills of the Precordillera due to the action of the fault Ramon, reaching 3296 metres at the Cerro de Ramon. 20 km further east is the Cordillera of the Andes with its mountain ranges and volcanoes, many of which exceed 6,000 m (19,685.04 ft) and in which some glaciers are maintained.

Salar de Uyuni to the Andes Mountains, Bolivia – February 9th, 2011

February 9th, 2011 Category: Image of the day, Mountains, Salt Flats

Bolivia - January 15th, 2011

Salar de Uyuni covers 10,582 square kilometers (4,086 sq mi) of terrain in the Bolivian departments of Potosí and Oruro, making it the world’s largest salt flat. It is located at an elevation of 3,656 meters (11,995 ft) above mean sea level, near the crest of the Andes.

Here, the ridges of the Andes Mountains can be seen to the east. The terrain appears dry on the western side, yet green and fertile on the eastern side. In the full image, part of Paraguay can be observed east of the salar and the mountains, while part of Argentina is visible to the southeast, and part of Chile south of the salar.

Andes Mountains Dividing High Arid Terrain from Low Vegetated Plains, South America

November 14th, 2010 Category: Lakes, Mountains, Salt Flats

Argentina - November 5th, 2010

The Andes Mountains run down the center of this image of Bolivia (above), Chile (lower left) and Argentina (lower right), neatly dividing the lower, more fertile terrain to the east from the arid, high plateaus to the west.

The bright white area in the upper left corner is the salt flats of the Salar de Uyuni, in Bolivia. The green area in the lower right corner is Mar Chiquita, a salt lake in Argentina.
