Nunataks, also known as glacial islands, are unique geological formations that rise above ice sheets or glaciers, creating isolated mountain peaks that appear as islands in a sea of ice.

They are most commonly found in polar regions like Antarctica and Greenland, and high-altitude areas with extensive glacial coverage, such as the Himalayas, Andes, and the Rocky Mountains.

The term “nunadak” originates from the Inuit language and refers to these isolated peaks that protrude above the ice surface.
