Ice cap

An ice cap is an ice mass that covers less than 50 000 km² of land area (usually covering a highland area). Masses of ice covering more than 50 000 km² are termed an ice sheet.^[1]^[2]

Ice caps are not constrained by topographical features (i.e., they will lie over the top of mountains) but their dome is usually centred around the highest point of a massif. Ice flows away from this high point (the ice divide) towards the ice cap's periphery.^[1]

Vatnajökull is an example of an ice cap in Iceland.^[3]
