Trango Tower, Ascent of Southeast Face and Tragedy. A four-man Norwegian team climbed a very difficult new route on the southeast face of the main Trango Tower (6237 meters, 20,463 feet). It took them 21 days in unstable weather to reach the summit above this 5000-foot-high route. On August 5 Hans Christian Doseth and Finn Doehli were watched from Base Camp by Stein Aasheim and Dag Kolsrud as they reached the summit. When they did not return, an unsuccessful search was initiated. It is assumed that they fell during the descent.
