Pumori
Pumori is a majestic 7,161-meter pyramidal mountain in the Mahalangur section of the Himalayas, rising eight kilometers west of Mount Everest on the international border between Nepal and Tibet. George Mallory bestowed its name, which translates in the Sherpa language to 'Mountain Daughter' or 'Unmarried Daughter', honoring its geographic proximity to Everest.

Documented Climbing Routes (1)
Pumori Southeast Ridge
The Southeast Ridge is the classic normal route up Pumori (7,161m), rising steeply from the Pumori Base Camp near Gorak Shep to the sharp pyramid summit. The route ascends moraines to an advanced camp, tackles a steep rock rib and glacier headwall to Camp II, and negotiates sustained 50-degree ice slopes and intricate crevasses guarding the final shoulder and summit crest. While technically accessible compared to neighboring big walls, it demands serious respect due to exposure to unpredictable serac avalanches.
