STS109-711-56 Panoramic view south from central Argentina towards Patagonia: (where a distant dust plume off Bahia Blanca can be seen), with the Andes Mts and the Pacific Ocean on the right, and the Río de Plata on the Atlantic coast on the lower left. The large inland lake, known as Mar Chiquita, and the Paraná River floodplain, both supress cloud formation.

STS109-728-31 N. Argentina, Andes: Exceptional view of the rusty-looking volcanic High Andes and Altiplano; the long volcanic belt results from subduction of the Pacific oceanic plate beneath S. America. Toward the continent from the volcanic ranges are the narrow, thrust-faulted and folded ranges of the Precordillera, made up of ancient basement rocks and sedimentary strata almost identical to those of west-central Texas. This block of N. America became attached to S. America during a plate collision some 375 million years ago. The tremendous uplift of the Andes has brought these old rocks to the surface.

STS109-405-15 West-central Argentina: Aconcagua, highest point in South America at 6,960 m, is the snowy peak at left of this view. Once believed to be a volcano -- it is capped with a lava flow -- Aconcagua is now known to be a great basement-cored block that has been thrusted up to its present elevation. Mts. Amarillo, Mercedario and Ansilta are volcanic peaks lying to the north. A few of the narrow Precordillera ranges can be seen in the foreground

STS109-725-73 Mt. Aconcagua, Argentina: Highest point (6,960 m) in S. America. Layers of rock on the flanks of this uplifted block can be discerned in this detailed view. The deep, sharp valley heading toward the viewer is the principal pass over the Andes at this latitude. The mountain resort of Uspallata is just NE of the fork in the valley at right center. Ice-capped volcanic peaks Amarillo, Mercedario and Ansilta are in the foreground.

STS109-405-28 Central Andes Panorama: This grand view from over the Chaco Plain of Argentina, looks southwestward to Valparaiso, Chile on the Pacific coast. This segment of the Andes has few volcanoes and numerous peaks with elevations in excess of 20,000 feet, including Mount Aconcagua.

STS109-404-10 Mount Aconcagua, Argentina: This view of South America's highest mountain includes to small ice fields with glaciers on the north and eastern flanks of Mount Mercedario and Amarillo, both over 20,000 feet in elevation

STS109-404-21 Around Cerro Ojos del Salado (Argentina-Chile border): Peaks reach 21-23,000-ft; mountain climbers' mountains, acc. Grunsfeld; subduction-related volcanoes and folded/faulted strata; one of a fine stereopair with STS109-404-019

STS109-407-25 High Andean Glacier, Argentina: These small ice fields with glaciers are located on the eastern and northern flanks of the Andes north of Mount Aconcagua and west of the Rio De los Patos in west central Argentina.

STS109-404-6 Coquimbo, Chile: The smaller city of La Serena is situated on the river that enters Coquimbo Bay from the east. The Cero ToloIo Inter-American Observatory (CTIO) is roughly located in the lower left portion of this photo, below and to the right of the bright patch of mines and to the left (south) of the larger, green river valley.
