Canyonlands This fascinating photo was taken by the ASTER image on NASA’s terra satellite and provides a unique view of the Canyonlands National Park area. ASTER is a multi-spectral instrument, meaning that it takes images at different light wavelengths and those images are stitched together to give more information than would be found in a normal picture; the colors can tell more about the terrain and materials than images would otherwise. To the west of this image you see the Colorado River surrounded by a series of fault surfaces that run almost parallel to the river direction. East of the Colorado, two tributaries, the Dolores and San Miguel rivers have cut a series of highly-sinuous drainages that feed water into the main Colorado system. -JBB Image credit: NASA/GSFC http://m.flickr.com/#/photos/gsfc/10423895104/
