 Completion of the Seven Summits endeavor came on May 16, 2002 when Ershler and her husband reached the summit of Mount Everest.
 Ershler is the 4th American Woman to climb the Seven Summits and the 12th American Woman to climb Mount Everest.

 She is also the first female amputee to climb Mount Everest.
The Earth Day 20 International Peace Climb was an expedition to reach the summit of Mount Everest during Earth Week 1990 led by Jim Whittaker, the first American to climb Mount Everest (in 1963), and marked the first time in history that mountaineers from the United States, Soviet Union and China had roped together to climb a mountain, let alone Mount Everest.

Kharta is a region in Tibet lying to the east of Mount Everest and centred on the Kharta valley and Kama valley.
 The 40 km Kharta valley starts at the col at Lhakpa La at the head of the Kharta Glacier from which the Kharta Chu river flows east to join the Phung Chu just beyond Khata village.
 Nearby to the south, the Kama valley starts at the Kangshung Glacier at the foot of Everest's Kangshung Face, and the Kama Chu flows southeast to the Phung Chu.
 The 1921 British Mount Everest reconnaissance expedition discovered Kharta when reconnoitring ways to climb Mount Everest and managed to reach the North Col via the Lhakpa La.
 Since that time Kharta has not been used as a way to approach the summit of Everest but the two valleys have become a popular area for trekking.

 He is the author of best-selling non-fiction books—"Into the Wild", "Into Thin Air", "Under the Banner of Heaven", and ""—as well as numerous magazine articles.
 He was a member of an ill-fated expedition to summit Mount Everest in 1996, one of the deadliest disasters in the history of climbing Everest.
Maurice Wilson MC (21 April 1898 – c. 31 May, 1934) was a British soldier, mystic, mountaineer and aviator who is known for his ill-fated attempt to climb Mount Everest alone in 1934.
 Often characterised as "eccentric", he wished to climb Everest as a platform to promote his belief that the world's ills could be solved by a combination of fasting and faith in God.
 Despite his lack of mountaineering or flying experience, he succeeded in flying from Britain to India, surreptitiously entering Tibet and climbing as high as 6920 m on Mount Everest.
 However, he died in his attempt, and his body was found the following year by a British expedition.
Nawang Sherpa became the first person to climb Mount Everest with a prosthetic leg by reaching the summit on May 16, 2004 (see Mount Everest Timeline and Trivia).
 He is also the first amputee to reach the summit of Mount Everest on his first attempt, and the first disabled person from Asia to stand on the summit.
