Kara-Kul Structure, Tajikistan

Near the center of this scene is the mountain lake Kara-Kul, located in eastern Tajikistan, high in the Pamir mountain range near the Chinese border. The 25-kilometer (16 mi) diameter lake sits at an elevation of 6000 meters (20,000 ft) above sea level. Kara-Kul was formed from a meterorite impact approximately 25 million years ago, leaving a crater with a rim diameter of 45 kilometers (28 mi). Islands formed from the central uplift can be seen in the northern and southern parts of the lake. Interestingly, the Kara-Kul impact structure remained unidentified until it was discovered though studies of imagery taken from space.
