Image of a portion of the Magdalena Valley in Colombia, South
America, transmitted by Landsat (formerly ERTS) 2 on January 7, 1977. Green, red, and
infrared are recorded separately by the satellite and then combined to make the image.
Vegetation appears red, whereas barren land is green. The Magdalena River and nearby lakes
are blue; the white splotches are clouds. The roughly parallel north-south pattern along
the centre right indicates rock outcrops where the rocks have been bent into a folded
structure. Landsat 2 was launched January 22, 1975.
