===Winter expeditions===
* 1987/1988&nbsp;— Polish-Canadian-British expedition led by [[Andrzej Zawada]] from the Pakistani side, consisting of 13 Poles, 7 Canadians and 4 Brits. 2 March [[Krzysztof Wielicki]] and [[Leszek Cichy]] established camp III at {{convert|7,300|metres}} above sea, followed by Roger Mear and Jean-Francois Gagnon few days later. Hurricane winds and frostbite forced the team to retreat.<ref name="altitudepakistan.blogspot.com">{{cite web|url=http://altitudepakistan.blogspot.com/2014/11/history-of-winter-climbing-k2.html|title=History of Winter Climbing K2|website=altitudepakistan.blogspot.com|access-date=5 July 2018}}</ref>
* 2002/2003&nbsp;— Netia K2 Polish Winter Expedition. The team of fourteen climbers was led by [[Krzysztof Wielicki]], and included four members from Kazakhstan, Uzbekistan, and Georgia. They intended to climb North Ridge. Marcin Kaczkan, [[Piotr Morawski]] and [[Denis Urubko]] established camp IV at {{convert|7,650|metres}} above sea level. The final ascent started by Kaczkan and Urubko failed due to the destruction of the tent by harsh weather in camp IV and Kaczkan's [[cerebral edema]].<ref name="altitudepakistan.blogspot.com"/>
* 2011/2012&nbsp;— Russian expedition. Nine Russian climbers attempted K2's Abruzzi Spur route. They managed to reach {{convert|7,200|metres}} above sea level (Vitaly Gorelik, Valery Shamalo, and Nicholas Totmyanin) but had to retreat due to hurricane-force winds as well as [[frostbite]] on both of Gorelik's hands. After their descent to base camp and an unsuccessful call for Gorelik's evacuation (helicopter could not reach them through the worsening weather), the climber died of [[pneumonia]] and cardiac arrest. Following the incident, the expedition was called off.<ref name="altitudepakistan.blogspot.com"/><ref>{{cite web|url=http://www.alpinist.com/doc/web12w/newswire-vitaly-gorelik-dies-k2|title=Vitaly Gorelik Dies On K2 - Alpinist.com|website=www.alpinist.com|date=6 February 2012 |access-date=5 July 2018}}</ref>
