Ice field 冰原
(重定向自Icefield)
An ice field (also spelled icefield) is an area less than 50,000 km (19,000 sq mi) of ice often found in the colder climates and higher altitudes of the world where there is sufficient precipitation. It is an extensive area of interconnected valley glaciers from which the higher peaks rise as nunataks. Ice fields are larger than alpine glaciers, smaller than ice sheets and similar in area to ice caps. The topography of ice fields is determined by the shape of the surrounding land forms, while ice caps have their own forms overriding underlying shapes.
