K2 Remains Unconquered in Winter (2020)
For decades, mountaineers have attempted to climb K2 in winter, with the most recent being Apricot Tours in 2020. They have all failed, but data shows promise that it can be done.
Many expeditions have tried including the 2018 Krzysztof Wielicki expedition that rescued Elisabeth Revol on Nanga Parbat. Other expeditions were attempted it in 1988, 2003, 2012 and 2015, and 2019.
