The Geneva Spur, named Eperon des Genevois [2] and has also been called the Saddle Rib [3] is a geological feature on Mount Everest—it is a large rock buttress near the summits of Everest and Lhotse. [4] [5] The Geneva spur is above Camp III and the Yellow Band, but before Camp IV and South Col. [4] It is a spur [6] near the south col.
Mount Everest with snow melted, showing upper geologic layers in bands. Geologists have subdivided the rocks comprising Mount Everest into three units called formations. [52] [53] Each formation is separated from the other by low-angle faults, called detachments, along which they have been thrust southward over each other.
Kangshung Face of Mount Everest with its northeast ridge (No. 12, right) and the Three Pinnacles (No. 8) North face of Mount Everest: routes and important points The Three Pinnacles are a formation of steep rocks along the northeast ridge on Mount Everest.
It was surmounted in 1960 as part of the first ascent of Mount Everest via the north route, when a shoulder stand was used to climb the last 5 metres (16 ft). The step was first climbed unaided in 1985, by the Spanish Òscar Cadiach. He assessed the final rock face as 5.7 to 5.8 (V+ in UIAA classification).
Mount Everest is Earth's tallest mountain - towering 5.5 miles (8.85 km) above sea level - and is actually still growing. While it and the rest of the Himalayas are continuing an inexorable uplift ...
When climbers attempt to climb Everest via the North Ridge (Tibet), the first camp on the mountain itself (traditional Camp IV, modern Camp I) is established on the North Col. From this point at approximately 7,020 metres (23,030 ft) above sea level , climbers ascend the North Ridge to reach a series of progressively higher camps along the ...
The nappes—large, stacked sheets of rock—found in the Tethys Himalayan mountain range, are primarily composed of sedimentary rocks, such as limestone formed from the accumulation and compression of sediments like sand, mud, and shells deposited in the Neo-Tethys seabed during the Paleogene" (66 Mya–23 Mya).
