Description

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), with its multi-spectral infrared channels, displays the bands in red, green and blue respectively. As different materials reflect and emit energy in different ways, ASTER can provide detailed information about the composition of Earth's surface. The data have been computer enhanced to exaggerate the colour variations that highlight differences in types of surface materials. Salt deposits on the valley floor appear as yellow, green, purple, and pink, indicating the presence of carbonate, sulfate, and chloride minerals. The Panamint Mountains to the west and the Black Mountains to the east are made up of sedimentary limestones, sandstones, shales and metamorphic rocks. The bright red areas indicate the mineral quartz, found in sandstones; green areas are limestones. In the lower centre of the image is Badwater, the lowest point in North America.
