English: The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite acquired this image of Mount Redoubt and its surroundings. The volcano exhibits little visible activity besides a plume of vapour. In this false-colour image made from a combination of visible and infra-red light, the bright white steam plume hovers over the volcano’s summit. Immediately southwest of this plume, clouds appear fairly thin and dull. North of the volcano, pristine snow rests on the land surface, but southeast of the volcano, ashfall from earlier eruptions has stained the icy surface. The vegetation in the coastal areas and in river valleys is red.
