Ice cap - Wikipedia
In glaciology, an ice cap is a mass of ice that covers less than 50,000 km 2 (19,000 sq mi) of land area (usually covering a highland area). Larger ice masses covering more than 50,000 km 2 (19,000 sq mi) are termed ice sheets .

Ice cap | geology | Britannica
Annual layers of firn may often be detected by thin films of dust or ash that accumulate on the surface during each summer. Further compaction of firn, usually at a depth of 45 to 60 m (150 to 200 feet), results in glacial ice, distinguished by its impermeability to air and water.

What are ice caps and icefields? An ice cap is a dome-shaped glacier with an area less than 50,000 square kilometers (19,300 square miles) that flows in all directions and covers much of the underlying topography. Ice caps form in high-latitude polar and subpolar mountain regions.
Six ways loss of Arctic ice impacts everyone | Pages | WWF
Polar ice caps are melting as global warming causes climate change. We lose Arctic sea ice at a rate of almost 13% per decade, and over the past 30 years, the oldest and thickest ice in the Arctic has declined by a stunning 95%.
Ice Sheets - National Snow and Ice Data Center
Ice caps are essentially miniature ice sheets. An ice cap covers less than 50,000 square kilometers (19,300 square miles) and comprises several merged glaciers. Like ice sheets, ice caps tend to spread out in dome-like shapes as opposed to occupying a single valley or set of connected valleys.
