Glacier Types: Icefields

Icefields are expanses of ice similar to ice caps, only smaller, usually less than 50,000 square kilometers (19,300 square miles) in area. An icefield's flow is also more strongly influenced by the underlying mountains and topography.

Several glaciers flow from the icefield, including the large Brüggen Glacier on the right, and the Occidental Glacier on the far left. —Credit: Image provided by Earth Sciences and Image Analysis Laboratory at Johnson Space Center, courtesy NASA Earth Observatory

Photograph of the Harding IcefieldAs many as 40 glaciers flow from the Harding Icefield, which is located in the Kenai Mountains of Alaska. The icefield receives more than 400 inches of snow each year, and is one of only four icefields in the United States. —Credit: Photographer unknown. 1979. Courtesy United States Government.
