Campos de hielo  

定义

  • Icefields are expanses of glacial ice flowing in multiple directions. Like ice caps, icefields usually cover less than 50,000 square kilometers (19,300 square miles), so they are much smaller than the ice sheets blanketing Greenland and Antarctica. In contrast to ice caps, icefields are interrupted by peaks of the underlying mountain ridges, and those mountains influence the flow of the icefield. (en)
