Death Valley, Calif., has the lowest point in North America, Badwater at 85.5 meters (282 feet) below sea level. It is also the driest and hottest location in North America. Located in eastern California and western Nevada, Death Valley forms part of Death Valley National Park. The region is characterized by deep valleys and high mountain ranges, located in the large Basin and Range province of the western United States. This view looking towards the northwest was created by draping an Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) simulated natural color image over digital topography from the ASTER Global Digital Elevation Model (GDEM) data set. Furnace Creek ranch in the right foreground is the only place on the valley floor where vegetation grows year-round due to water channeled through Furnace Creek. The ASTER scene was acquired September 24, 2003, and is located near 36.4 degrees north latitude, 116.9 degrees west longitude.
Himalayan glaciers in Bhutan
In the Bhutan Himalayas, Advanced Spaceborne Thermal Emission and Reflection Radiometer data have revealed significant spatial variability in glacier flow, such that the glacier velocities in the end zones on the south side exhibit significantly lower velocities (9 to 18 meters, or 30 to 60 feet per year), versus much higher flow velocities on the north side (18 to 183 meters, or 60 to 600 feet per year). The higher velocity for the northern glaciers suggests that the southern glaciers have substantially stagnated ice. This view looking towards the northwest was created by draping an ASTER simulated natural color image over digital topography from the ASTER Global Digital Elevation Model (GDEM) data set. The ASTER scene was acquired November 20, 2001, and is centered near 28.3 degrees north latitude, 90.1 degrees east longitude.
