Lhotse is the 4th highest mountain in the world at 8,516 metres. It is the closest peak to Mt Everest as it is a part of Everest massif, rising across the South Col. Lhotse means “South Peak” in Tibetan. The main summit of Lhotse was first climbed on May 18, 1956, by the Swiss team of Ernst Reiss and Fritz Luchsinger from the Swiss Mount Everest/Lhotse Expedition. In 1979 Silesian Mountaineering Club form Poland organized national expedition, and on Oct 4 the main summit was ascenced by a team led by Andrzej Czok with Zygmunt Andrzej Heinrich, Janusz Skorek and Jerzy Kukuczka (Czok and Kukuczka clibed the peak without the use of supplemental oxygen, though Czok planned to do it that way and Kukuczka experienced equipment failure,and decided to go withoutoxygen. It was his first conquered eight-thousander, and eventually the last one to climb 10 years later). 4 days later second group climbed to the peak – Janusz Baranek, Adam Bilczewski, Stanisław Cholewa, Robert Niklas. Myself, I climbed with the group without the use of supplemental oxygen, but carrying one oxygen bottle to elevation of 8350 m, where I was forced to turn back due to inclement weather.
