KATHMANDU: Norwegian mountaineer Kristin Harila on Wednesday completed one of the rare feats in Himalayan mountaineering, summiting Mount Everest to finish her Khumbu Triple Crown, a single-season ascent of Nuptse, Lhotse, and Everest. 

According to Chhang Dawa Sherpa, Expedition Director at Seven Summit Treks, Harila reached the Everest summit at 8:50am.

The achievement caps a remarkable sequence. Harila first summited Nuptse (7,861m) on May 17 without supplemental oxygen, followed by Lhotse (8,516m) on May 21, and now Everest — all within the same spring season. She was accompanied throughout by Mingtemba Sherpa, who also fixed the Everest summit route earlier this season on May 13.

Harila had originally set out to complete all three peaks without supplemental oxygen. She used bottled oxygen on Lhotse, and which tempered the full scale of what the project had set out to achieve. The Nuptse and Everest ascents, however, were completed without it.

The Triple Crown, combining three neighbouring giants of the Khumbu in a single season, is considered among the most demanding objectives in the range. Seven Summit Treks organised and managed the expedition.

Both Harila and Mingtemba have previously summited all 14 eight-thousanders. Harila set the world speed record for that achievement in 2023, completing all 14 peaks in just 92 days.
