Changtse (Tibetan: "north peak") is a mountain situated between the Main Rongbuk and East Rongbuk Glaciers in Tibet, China, immediately north of Mount Everest.
 It is connected to Mount Everest via the North Col.
Guy Henry Bullock (23 July 1887 – 1956) was a British diplomat who is best known for his participation in the 1921 British Mount Everest reconnaissance expedition.
 As expedition mountaineers, he and George Mallory found a northern access route to Everest by climbing the 6849 m Lhakpa La col above the East Rongbuk Glacier and by going on to reach the North Col at 7020 m .
 They did not, however, reach the summit of Mount Everest.
After World War II, with Tibet closing its borders and Nepal becoming considerably more open, Mount Everest reconnaissance from Nepal became possible for the first time culminating in the successful ascent of 1953.
 In 1950 there was a highly informal trek to what was to become Everest Base Camp and photographs were taken of a possible route ahead.
 Next year the 1951 British Mount Everest reconnaissance expedition reconnoitred various possible routes to Mount Everest from the south and the only one they considered feasible was the one via the Khumbu Icefall, Western Cwm and South Col.
 In 1952, while the Swiss were making an attempt on the summit that nearly succeeded, the British practised their high-altitude Himalayan technique by attempting Cho Oyu, nearby to the west.
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.
Toshio Yamamoto is a Japanese mountaineer who summited Mount Everest in 2000 at the age of 63.
 This was noted in world news for becoming the oldest person up to that time to summit Mount Everest.
 Toshio summited Mount Everest on May 19, 2000 via the North Col, with Tosio Nakamura as the expedition team leader.
Disteghil Sar or Distaghil Sar (Urdu: ‎ ) is the highest mountain in the Hispar Muztagh, a subrange of the Karakoram mountain range, in Gilgit-Baltistan.
 It is the 19th highest mountain on earth and the 7th highest peak in Pakistan.
 Destghil sar is a Wakhi language word, that means "above the inner ranch."
 The mountain has an about 3 km long top ridge above 7400m with three distinct summits: (north)west 7885m, central 7760 m, and (south)east 7696m or 7535m ().
Tsewang Paljor (10 April 1968 – 10 May 1996) was a member of the first Indian team to reach the summit of Mount Everest from the North Col.
 Tsewang Paljor was one among three Indians who died on the mountain during the 1996 Mount Everest disaster.
 While descending from the summit, he was trapped in a blizzard, and died due to exposure.
 He is believed by some to be the unidentified climber called "Green Boots" whose body was used by some as a trail marker.
Kala Patthar, meaning 'black rock' in Nepali and Hindi, is a notable landmark located on the south ridge of Pumori in the Nepalese Himalayas above Gorakshep.
 Although not a proper mountain, with a prominence of only , the ascent of Kala Patthar is very popular with trekkers in the region of Mount Everest since it provides the most accessible closeup view of Everest.
 Due to the structure of the Everest Massif, its high summit is blocked by Nuptse from much of the surrounding region.
 The views of Everest, Nuptse and Changtse are spectacular from Kala Patthar and there are glimpses of the northern flank and summit of Lhotse.
 The world's highest webcam, Mount Everest webcam, is located here.
Tsewang Samanla was one among three Indians who died on Mount Everest in the 1996 Mount Everest disaster.
 He was a member of the first Indian team to reach the summit from the North Col.
 It is believed that Samanla descended later than his companions.
 While descending from the summit, all three were trapped in a blizzard, and died due to exposure.
 His body remains on the mountain.
