ISLAMABAD: World Day for Glaciers will be celebrated across the globe on 21 March 2025. Here is a look at some of the biggest glaciers from around the world.
Siachen Glacier
According to NASA’s Earth Observatory, Siachen is the second-longest glacier within Earth’s midlatitudes, which exclude, for example, the continental glaciers of Antarctica and Greenland. It measures 75 kilometres (47 miles) long and is 3.5 kilometres (2.2 miles) wide at the top-centre. This remote part of the world is uninhabited and lies well above the tree line.


Lambert Glacier
According to Agenda Malvinas, Lambert Glacier, located in the remote and frigid East Antarctica, is recognised as the largest glacier in the world. This ice colossus stretches over 400 km and reaches a depth of up to 2,500 metres, making it a geographical wonder of epic proportions.

Vatnajökull glacier
Vatnajökull (2110 m) is the largest glacier in Iceland and it’s also the largest glacier mass in Europe, according to Iceland on the Web. It covers an area of roughly between 8100 sq. km and 8300 sq. km, and it’s about 1000 m thick at its thickest point.
Bering Glacier
According to Michigan Tech, the Bering Glacier is the largest and longest glacier in continental North America. The largest temperate surging glacier on Earth, it has surged at least six times during the twentieth century, most recently in 1993-1995. It is currently retreating.
Furtwängler Glacier
According to Altezza Travel, the Furtwängler Glacier is the most iconic glacier on Africa’s Mount Kilimanjaro. Located near the main peak, Uhuru, it draws many adventurers eager to climb Kilimanjaro and experience the glacier’s breathtaking beauty before it vanishes.

Tasman Glacier
The Tasman Glacier stretches over 23 km (about 14 miles) long, making it the longest glacier in New Zealand, according to Mt Cook Glacier Guiding. It is between 1-2km wide and very deep. The glacier covers an area of approximately 101 square km (around 39 square miles) and contains nearly one-third of all glacier ice in New Zealand. During spring and winter up to 12.5m (0ver 40 feet) of snow can fall at the top of the Tasmin Glacier.
