Writing I

Study the information below about Pasang Lhamu Sherpa; the first Nepali woman to scale Mt. Everest. Write a short biography of her based on the given information.

Pasang Lhamu Sherpa

Pasang Lhamu Sherpa was born on December 16, 1961, in Solukhumbu, Nepal. She grew up in a mountaineering family and started climbing mountains in her teens. At the age of 17, she went to Kathmandu with her husband, Lhakpa Sonam Sherpa, and together they owned a travel agency.

In 1989, Pasang Lhamu Sherpa made her first attempt to climb Mount Everest, but she was unable to reach the summit. She did, however, climb Mount Pisang (6091m) and Mount Blanc (4848m). In 1991, she made two more attempts to climb Mount Everest, but she was only able to reach 8750m and 8500m respectively.

On April 22, 1993, Pasang Lhamu Sherpa finally reached the summit of Mount Everest. She was the first Nepali woman to do so. However, she died on the way down due to bad weather. She was 31 years old.

Pasang Lhamu Sherpa is a national hero in Nepal. She is an inspiration to women all over the world. In her honor, a highway and a mountain have been named after her. She is also the subject of a documentary film, “Pasang Lhamu: The First Sherpa Woman on Everest.
