Mount Everest, the world’s highest peak above sea level, is located in the Mahalangur Himal sub-range of the Himalayas. More precisely, it sits on the border between Nepal and Tibet, China. This colossal mountain, revered and challenged by climbers worldwide, is not just about its towering height but also its dramatic geological features and extreme climate, all contributing to its iconic status and the answer to the question: where is Mount Everest situated in the grand scheme of our planet?
Geological Formation and Mountain Relief

The very existence of Mount Everest is a result of powerful tectonic forces. The Himalayas, including Everest, were formed by the collision of the Indian-Australian and Eurasian plates, a process that began roughly 40 to 50 million years ago. As the Indian-Australian Plate pushed northward and was forced under the Eurasian Plate, known as subduction, the landmass was thrust upwards, creating these monumental mountain ranges. The Himalayas themselves started their ascent around 25 to 30 million years ago, with the Great Himalayas, the range containing Everest, taking shape during the Pleistocene Epoch, which ended about 11,700 years ago. Everest and its neighboring peaks are at the heart of this intense tectonic activity within the Great Himalayas, acting as a central point, or knot, of geological forces. Remarkably, even today, instruments on Everest show that the mountain continues to inch northeastward and upward annually, a testament to the ongoing geological processes.
The name “Everest” itself is sometimes mispronounced, with common errors being “Ever-est” or “Ev-rest.” The correct pronunciation, mirroring the surname of Sir George Everest, after whom the mountain is named, is “EVE-rest.”
Mount Everest’s geological composition is as fascinating as its formation. It is built from multiple layers of rock that have been folded over on themselves, known as nappes. The lower sections of the mountain are composed of metamorphic schists and gneisses, topped with igneous granites. At higher altitudes, sedimentary rocks of marine origin are found, remnants of the ancient Tethys Sea floor that existed before the Indian and Eurasian plates collided and closed it off. A distinctive feature is the Yellow Band, a prominent limestone formation clearly visible just below the summit pyramid, marking a significant geological layer within Everest.
The summit of Everest is the culmination of the stark Southeast, Northeast, and West ridges. Close to the main summit is the South Summit, a smaller peak on the Southeast Ridge reaching 28,700 feet (8,748 meters). The northeastern face of Everest provides a direct view of the peak, rising dramatically about 12,000 feet (3,600 meters) above the Tibetan Plateau. Surrounding Everest are other significant peaks: Changtse (24,803 feet or 7,560 meters) to the north, and Khumbutse (21,867 feet or 6,665 meters), Nuptse (25,791 feet or 7,861 meters), and Lhotse (27,940 feet or 8,516 meters) to the west and south, all contributing to the majestic landscape around Everest’s base.
The Khumbu Icefall at the base of Mount Everest in Nepal, a chaotic glacier section, presents a formidable and visually striking landscape.
Everest’s shape resembles a three-sided pyramid. These sides are known as faces, and the lines where they meet are ridges. The North Face, overlooking Tibet, is defined by the North and West Ridges, and includes features like the Great and Hornbein couloirs and the North Col. The Southwest Face, facing Nepal, is bordered by the West and Southeast Ridges, and is known for the South Col and the Khumbu Icefall, a notoriously treacherous and shifting field of ice blocks that poses a significant challenge to climbers. The East Face, or Kangshung Face, also above Tibet, is bounded by the Southeast and Northeast Ridges.
The Everest summit is capped with rock-hard snow, topped by a fluctuating layer of softer snow, varying by 5–20 feet (1.5–6 meters) throughout the year. The snow level is highest post-monsoon in September and lowest in May after winter winds. The extreme altitude means the summit atmosphere contains only one-third of the breathable oxygen found at sea level. Combined with fierce winds and extreme cold, these conditions prevent any plant or animal life at the summit and upper slopes.
Drainage and Climate

Glaciers are integral to the landscape of Everest, covering its slopes down to the base. Notable glaciers include the Kangshung Glacier to the east; the East, Central, and West Rongbuk glaciers to the north and northwest; the Pumori Glacier to the northwest; and the Khumbu Glacier to the west and south. The Khumbu Glacier is fed by the Western Cwm, a valley of ice nestled between Everest and the Lhotse-Nuptse Ridge. Glacial activity is a major force in the continuous erosion of Everest and the other high Himalayan peaks, shaping the rugged terrain.
The drainage patterns around Everest radiate outwards. Meltwater from the Khumbu Glacier feeds into the Lobujya River in Nepal, which becomes the Imja River, eventually joining the Dudh Kosi River flowing southwards. In Tibet, the Rong River originates from the Pumori and Rongbuk glaciers, and the Kama River from the Kangshung Glacier. Both the Rong and Kama Rivers flow into the Arun River, which cuts through the Himalayas into Nepal. These river valleys—Rong, Dudh Kosi, and Kama—serve as the northern, southern, and eastern access routes to the Everest summit, respectively, highlighting how geography dictates routes to the top.
The climate on Mount Everest is perpetually hostile. Even in July, the warmest month, the average daytime summit temperature is a frigid −2 °F (−19 °C). January, the coldest month, sees average summit temperatures of −33 °F (−36 °C), with potential drops to −76 °F (−60 °C). Storms can arise rapidly, causing sudden temperature plunges. Everest’s peak reaches into the lower jet stream, exposing it to sustained winds exceeding 100 miles (160 km) per hour. Precipitation mainly occurs as snow during the summer monsoon season, from late May to mid-September. The extreme cold and harsh conditions mean that frostbite is a constant and severe risk for climbers attempting to reach the summit of Mount Everest.
In conclusion, Mount Everest is geographically situated in the Himalayas, on the border of Nepal and Tibet. Its location is characterized by extreme geological activity, contributing to its immense height and dramatic relief, and a relentlessly cold and hostile climate, shaped by its high altitude and exposure to severe weather patterns. Understanding where Mount Everest is goes beyond just pinpointing it on a map; it involves appreciating the complex interplay of geological and climatic forces that define this iconic and challenging peak.
