STS056-152-038 Karakorum Mountains (K2), China April 1993 K2 (Mount Goodwin-Austin), the world's second tallest mountain peak (28250 feet - 8611 meters above sea level), is discernible as a small concentration of white slightly left of center. Located on the Pakistan (south) and China (north) border, K2 was not successfully climbed until 1954. In addition to this isolated peak, several other peaks in this scene exceed 23000 feet (7010 meters) above sea level. Several sizable glaciers are visible (linear, whitish-looking features), mainly on the Pakistan side of the border. The glaciated river valleys (dark linear features) drain northward towards the interior in the top half of the image, while the glaciated valleys in the southern half of the image are tributaries of the Indus River Basin. STS56-152-033 has a small area along its southeastern corner that provides some overlap with this image (upper left).
