Overview
A Majestic Mountain Range
The Karakoram, a significant mountain range situated in the Kashmir region, spans the borders of Pakistan, China, and India. Its northwestern reaches extend into Afghanistan and Tajikistan. Predominantly located within Pakistan's Gilgit-Baltistan region, it forms part of the larger Trans-Himalayan mountain system.
Global Significance
Recognized as the second-highest mountain range on Earth, the Karakoram is part of a complex geological formation that includes the Pamir Mountains, Hindu Kush, and the Indian Himalayas. It boasts eighteen summits exceeding 7,500 meters, with four peaks surpassing 8,000 meters, including K2, the second-highest mountain globally.
Glacial Dominance
With a length of approximately 500 kilometers (310 miles), the Karakoram is distinguished by its extensive glaciation, holding the title of the most glaciated region outside the Earth's polar areas. The Siachen Glacier and Biafo Glacier are notable examples, ranking as the second and third longest glaciers outside these polar regions, respectively.
Geographical Context
Boundaries and Extent
The Karakoram range is geographically defined by several key features. To the east lies the Aksai Chin plateau, while the northeastern boundary is marked by the Tibetan Plateau. The Kunlun Mountains form the northern border, separated by the Yarkand and Karakash river valleys. To the northwest, the Pamir Mountains are situated. The southern boundary is delineated by the Gilgit, Indus, and Shyok rivers, which separate the Karakoram from the northwestern Himalayas.
Dimensions and Connectivity
The range stretches approximately 500 kilometers (310 miles) in length. It serves as a critical nexus, connecting with other major mountain systems such as the Pamir Mountains, Hindu Kush, Kunlun Mountains, and the Himalayas. The Karakoram Pass, historically a vital trade route between Ladakh and Yarkand, lies near the range's center, though this route is now largely inactive.
Etymology and Nomenclature
Turkic Origins
The term "Karakoram" is derived from Turkic languages, translating to "black gravel." This name was initially applied by Central Asian traders to the Karakoram Pass. Early European explorers, including William Moorcroft and George Hayward, later extended this designation to the mountain range west of the pass, sometimes using "Muztagh" (meaning "Ice Mountain") for the area now known as the Karakoram.
Historical Designations
During the 1850s, surveyors from the Survey of India, led by Thomas Montgomerie, assigned alphanumeric codes (K1 through K6, and beyond) to prominent peaks visible from Kashmir Valley. In traditional Indian geography, the mountains were known by names such as Krishnagiri, Kanhagiri, and Kanheri, all signifying "black mountains."
Regional Names
The range is referred to by various names across different cultures. In Chinese, it is known as Kǎlǎkùnlún shānmài (喀喇昆仑山脉), literally meaning "Kara-Kunlun mountain range." Tibetan speakers refer to it as Kha ra kho rum ri, transliterated via Wylie as 'kha ra kho rum ri'. In Uyghur, it is known as ق[[قارا قۉرۇم]] (Qara Qorum).
Exploration History
Early Expeditions
Due to its extreme altitude and rugged terrain, the Karakoram has historically been less populated than other Himalayan regions. European exploration began in the early 19th century, followed by systematic surveys conducted by British surveyors starting in 1856. Key expeditions in the late 19th and early 20th centuries, such as those led by Francis Younghusband and George K. Cockerill, were instrumental in mapping the region's geography.
Mapping and Surveying
The term "Karakoram" itself was applied to various parts of the range by early explorers, including Kenneth Mason, who used it for the Baltoro Muztagh. The modern understanding of the range's extent, from the Batura Muztagh in the west to the Saser Muztagh in the east, solidified through these extensive survey efforts. Floral surveys were also conducted in specific catchment areas during the late 20th century.
Geology and Glaciers
Tectonic Activity
The Karakoram lies within a highly active geological zone, situated at the convergence boundary between the Indo-Australian and Eurasian tectonic plates. This dynamic setting contributes to the range's dramatic topography and geological features.
Glacial Features
A substantial portion of the Karakoram, estimated between 28% and 50%, is covered by glaciers, encompassing over 15,000 square kilometers. This extensive glaciation significantly exceeds that of the Himalayas and the Alps. While many glaciers worldwide are retreating rapidly, Karakoram glaciers exhibit a more complex behavior. Many are covered by a protective layer of debris, which insulates the ice and slows melting. However, where this insulation is absent, retreat rates can be high.
Notable Peaks
The Giants of Karakoram
The Karakoram is renowned for its concentration of high-altitude peaks. It hosts four mountains exceeding 8,000 meters and eighteen peaks above 7,500 meters. K2, the undisputed monarch of the range, stands as the second-highest mountain on Earth.
Key Peaks
K2 (8,611 m): The highest peak in the Karakoram and the second-highest mountain on Earth, known for its extreme difficulty and technical climbing challenges.
Gasherbrum I (8,080 m): Also known as Hidden Peak, it is the 11th highest mountain globally.
Broad Peak (8,051 m): Located adjacent to K2, it is the 12th highest mountain in the world.
Gasherbrum II (8,034 m): The 13th highest mountain, considered one of the more accessible 8,000-meter peaks.
The Last Ice Age
Glacial Extent
During the last glacial period, the Karakoram experienced a vastly different glacial landscape. A connected system of glaciers extended from western Tibet to Nanga Parbat and from the Tarim Basin down to the Gilgit District. The Indus glacier, a major valley glacier, flowed approximately 120 kilometers from the Nanga Parbat massif down to an elevation of 870 meters.
Scale of Ancient Glaciers
In contrast to the current maximum glacier length of 76 kilometers, the Ice Age valley glaciers were significantly longer, with some branches and main valley glaciers reaching up to 700 kilometers in length. The snowline during this period was considerably lower, approximately 1,300 meters below present-day levels, facilitating this extensive glacial coverage.
