Ice fields and ice caps are smaller than ice sheets (less than 50,000 sq. km or 19,305 sq. mi in area). They are also large bodies of ice that collect in high elevation catchment areas and are drained by smaller outlet glaciers.
Is it an ice field or an ice cap? The answer depends on how much the ice flow is dictated by the surrounding topography:
- Ice fields have mountains and ridges that jut out above the ice and influence its flow.
- Ice caps submerge the land beneath them, forming a high dome of slow-moving ice that spreads out from its center.
