Pumori (or Pumo Ri) is a mountain on the Nepal- Tibet border in the Mahalangur section of the Himalayas. Pumori lies just eight kilometres west of Mount Everest. Pumori, meaning "the Mountain Daughter" in Sherpa language, was named by George Mallory. "Pumo" means young girl or daughter and "Ri" means mountain in Sherpa language. Climbers sometimes refer to Pumori as "Everest's Daughter". Mallory also called it Clare Peak, after his own daughter.
Pumori is a popular climbing peak and the easiest route is graded class 3, although with significant avalanche danger. Pumori was first climbed on May 17, 1962 by Gerhard Lenser on a German- Swiss expedition. Two Czechs (Leopold Sulovský and Zdeněk Michalec) climbed a new route on the south face in the spring of 1996.
An outlier of Pumori is Kala Patthar (5,643m/18,513'), which appears as a big brown bump below the impressive south face of Pumori. Many trekkers going to see Mount Everest up close will attempt to climb to the top of Kala Patthar.
