La Rioja, Argentina
In this 1985 Landsat 5 image, a myriad of colors denote the composition and textures of the Sierra de Velasco Mountains of northern Argentina. Pink tones and warm hues indicate the drier, more barren areas of the mountains. Ribbons of blues and greens hint at the moister areas of vegetation and heavy growth. At the base of the mountains in the lower left, a pink area marks the city of La Rioja,
which is the capital city of one of the least populated and most arid provinces of Argentina. In stark contrast, the upper right of the image shows the lusher surroundings of the city of San Fernando del Valle de Catamarca and extensive vineyards.
