EDITORThe Panmah Glacier is one of the many remarkable glaciers located in the Karakoram Range, which stretches across the borders of Pakistan, India, and China. Renowned for its stunning yet formidable terrain, the glacier is situated in the remote and rugged northern region of Pakistan, specifically in the Gilgit-Baltistan territory. It is an area known for its high-altitude peaks, including K2, the second-highest mountain in the world. The Panmah Glacier plays a critical role in the local hydrology, ecology, and the region’s overall climate dynamics.
Geographic and Geological Characteristics
Location and Extent: The Panmah Glacier is situated in the Karakoram Range, within the Gilgit-Baltistan region of Pakistan. It lies at a latitude of approximately 35.78°N and a longitude of 76.20°E. The glacier spans an estimated length of 23 kilometers (14 miles) and varies in width between 1.5 to 2.5 kilometers. The glacier is nestled among some of the most formidable peaks of the Karakoram, with elevations ranging from 4,000 to 6,000 meters above sea level.
Geological Composition: The glacier, like many in the Karakoram, is predominantly composed of firn, névé, and glacial ice, which undergoes continuous transformation through the processes of compaction and recrystallization. The bedrock beneath the glacier is primarily composed of metamorphic rocks, including schist and gneiss, along with granitic intrusions, typical of the region’s geological history shaped by the collision of the Indian and Eurasian plates.
Glaciological Features
Mass Balance and Dynamics: The Panmah Glacier, in line with the Karakoram Anomaly, exhibits a relatively stable mass balance compared to other glaciers globally. Its accumulation zone is located at higher elevations where snow accumulates, primarily through winter precipitation. The ablation zone, where melting occurs, is lower down the glacier. The equilibrium line altitude (ELA) on Panmah Glacier, marking the boundary between accumulation and ablation, is typically around 5,200 to 5,500 meters, depending on annual climatic variations.
The glacier’s flow dynamics are influenced by its steep gradient, with velocities recorded in the range of 100 to 150 meters per year in the central flow line. However, the velocities near the glacier’s terminus are significantly lower due to the increased friction with the bedrock and the accumulation of debris.
Crevasses and Icefalls: The glacier features several crevassed zones, particularly in its upper reaches where the ice flow is faster and the gradient steeper. These crevasses can be tens of meters deep, posing significant hazards to mountaineers and researchers. Icefalls are also prominent, particularly where the glacier descends steeply or where tributary glaciers join the main glacier, causing differential ice flow.
Debris Cover: A significant portion of the lower Panmah Glacier is covered by a thick layer of supraglacial debris, composed of rocks, soil, and organic material. This debris originates from the surrounding steep slopes, which frequently experience rockfalls and avalanches. The debris cover acts as an insulating layer, reducing the rate of ice melt beneath it, thereby affecting the glacier’s overall mass balance and dynamics.
Hydrology
Meltwater Contribution: The Panmah Glacier is a critical source of meltwater, contributing to the Braldo River, which eventually feeds into the Indus River. The meltwater discharge is highly seasonal, with peak flows occurring during the summer months when temperatures are highest, and solar radiation is most intense. The glacier’s meltwater is crucial for downstream irrigation, hydroelectric power generation, and as a water supply for local communities.
Glacial Lakes and GLOFs: Several proglacial and supraglacial lakes form periodically near the glacier’s terminus, fed by meltwater and sometimes by calving icebergs. These lakes pose a risk of glacial lake outburst floods (GLOFs), which can result from the sudden breach of natural ice or moraine dams. Monitoring these lakes is essential for early warning systems to mitigate the impact of potential GLOFs.
Monitoring and Research Techniques
Remote Sensing: Due to the challenging terrain and extreme weather conditions, remote sensing techniques are extensively used to monitor the Panmah Glacier. Satellite imagery, including data from Landsat, Sentinel, and TerraSAR-X, provides valuable information on glacier surface velocities, changes in glacier extent, and surface elevation changes. Additionally, Synthetic Aperture Radar (SAR) is used to penetrate through cloud cover and darkness, offering all-weather monitoring capabilities.
In-situ Measurements: Where feasible, in-situ measurements are conducted to gather detailed data on glacier dynamics. This includes the installation of stakes for ablation and accumulation measurements, GPS surveys to track glacier movement, and automatic weather stations (AWS) to record temperature, precipitation, and other meteorological parameters. Ground-penetrating radar (GPR) is also employed to measure ice thickness and bed topography.
Modeling Glacier Dynamics: Numerical models, such as those based on the finite element method, are used to simulate the glacier’s flow dynamics and predict future changes under different climatic scenarios. These models incorporate data from remote sensing and in-situ measurements to improve accuracy. The models help in understanding the glacier’s response to climatic variables and in forecasting its long-term behavior.

November 18, 2024Khewra Salt Mines
I just came to know that Pakistan is ranked the second number in the world’s list of salt reserves. So I thought it better to share it with you as well. Most of the salt reserves are located in the district of Jhelum in the Punjab province. In this write, I would like to introduce you to Khewra Salt Mines.
Khewra Salt Mines
Khewra Salt Mines are a bit far from Islamabad. The distance is around 160 kilometers from Islamabad and approximately 15 kilometers north of the Jhelum settlement of Pind Dadan Khan. This place is more fascinating and attractive for the tourist. This amazing place was discovered in 326 BC by the army of Alexander the Great while marching through Pakistan with their horses. Luckily their horses started licking the rocks so a soldier replicated them and revealed the secret. And today it has been ranked at the second number in terms of size.
Khewra Mine Looks Like
The Khewra Salt Mines are the earliest salt mines in the history of salt mining on the Indian subcontinent. In the form of an irregular dome-like structure, salt is found in nature. It is possible to find seven broad salts seems with a combined thickness of around 150 meters. This is the place where one can find 99 percent pure salt. More interestingly you would find different colors of salt like transparent, white, pink, reddish, or beef-color red.
It is not just a salt mine but a full-fledged closet to visit. The mines are filled with architectural wonders such as mosques, a copy of the Minar-e-Pakistan, a sanatorium, Chaghi Mountain, and various other brightly colored structures made entirely of salt bricks. The monuments are illuminated from within by lights. One can find Sheesh Mahal which is also known as the palaces of mirrors. The walls of the palace are made up of clear salt and water pools are lighten up with lamps.
Besides, its popularity for high-quality salt, it is also known for its gypsum, marble, lime clay, potash, coal, and a variety of other minerals.
Annual Production of Salt
Khewra mines are regarded to be the most ancient in the history of salt mining on the subcontinent. Salinity was assessed to be 98 percent pure in 2018, resulting in the annual production of 389,134 tons of pure salt. In addition to the cash generated by the production, a substantial amount is generated by the approximately 40,000 visitors who come to the site every month. The anticipated yearly production of pink, white, & red salt is about 347,000 tons, with the majority of it being sold to China, India, the United States, and Germany.
By knowing this I think this is a worth visiting place. And amazingly the visiting ticket cost just 220 Rupees per head and half for students and children. Moreover, the visiting timing is from 9 am to 5 pm.
Ranikot Fort, often dubbed as the “Great Wall of Sindh,” is one of Pakistan’s most fascinating and enigmatic historical landmarks. Situated near the town of Sann in Jamshoro District, Sindh, the fort is recognized as one of the largest in the world, with a perimeter of around 32 kilometers (20 miles). Despite its immense size and strategic location, much about its origins remains a mystery, adding to its allure and significance as a cultural and historical monument.
Historical Background
Ranikot Fort is believed to have been originally constructed in the first half of the 17th century, though there are varying accounts about its exact origins. Some historians suggest that it may date back even further, to the reign of the Sassanian Empire or earlier. It was later renovated and expanded during the rule of the Talpur Mirs in the early 19th century, as they sought to fortify their domain against external threats.
The purpose of the fort, however, remains unclear. While some believe it was built as a defense against invasions, others argue that it was a means of securing trade routes or serving as a safe haven for local rulers. The lack of any major historical records associated with significant battles or sieges at Ranikot adds to the ambiguity surrounding its function.
Architectural Marvel
The scale of Ranikot is staggering, covering an area of approximately 32 square kilometers. The fort’s massive walls snake across the barren landscape, resembling the Great Wall of China, with which it is often compared. Constructed from limestone and sandstone, the fort’s walls rise up to 6 meters (20 feet) in height and are punctuated by several bastions and watchtowers.
Ranikot has four main gates: Sann Gate, Amri Gate, Shah-Pere Gate, and Mohan Gate, each offering access to different sections of the fort. The Sann Gate, located on the eastern side, is the main entrance and is notable for its intricate design and stonework.
Within the fort’s vast expanse lies another fortification known as the “Meeri” or “Mirikot,” a small fort within the larger walls that served as the residence of the Talpur Mirs. This inner fort has its own gates and walls, adding an additional layer of defense. The Meeri Fort is perched on a hill, providing a commanding view of the surrounding landscape.
The Great Wall of Sindh
The fort’s walls, stretching across the arid hills, resemble a smaller version of the Great Wall of China. This feature has earned Ranikot the nickname “The Great Wall of Sindh.” The zigzagging walls extend for miles, blending into the rocky terrain, and are a stunning sight, especially at sunrise or sunset when the golden light casts long shadows over the surrounding desert.
Unlike the Great Wall of China, however, Ranikot is not located in a highly populated or strategically important area. Its remote location has contributed to the fort’s air of mystery, as well as its relative obscurity in the global historical and architectural landscape.
Mysteries and Theories
The true purpose of Ranikot Fort is still shrouded in mystery. Scholars and historians have proposed various theories about why it was built, ranging from a defense structure against invasions from Central Asia to a royal retreat for the Talpur dynasty. Some suggest that it was intended to protect the local population from bandits and raiders, while others believe it may have been a strategic point for controlling trade routes passing through the region.
One of the most intriguing aspects of Ranikot is the lack of significant historical records or evidence of major battles taking place there. Its size and scale suggest that it must have had some important function, yet it remains an enigma to this day.
Cultural Significance
Ranikot Fort is not only an architectural marvel but also a cultural treasure. It stands as a testament to the rich history of Sindh, a region that has been home to ancient civilizations, including the Indus Valley Civilization. The fort’s design reflects the influences of various dynasties and cultures that have ruled over Sindh, from the Greeks and Mauryas to the Mughals and Talpurs.
In modern times, Ranikot has gained recognition as a symbol of Sindh’s historical heritage. The fort has been nominated for inclusion in UNESCO’s World Heritage Sites list, which would help preserve and promote this incredible site on a global stage.
