Thumbnail Sierra de Velasco

Shimmering blues and greens accentuate the textures of the Sierra de Velasco Mountains of northern Argentina. The urban area (pinkish circle) near the lower left part of the mountain range is La Rioja, the capital of the province of La Rioja. Follow the foothills to the upper right, where the city of San Fernando del Valle de Catamarca lies near extensive vineyards and fruit-growing areas (blue blocky shapes).
