     (Geol.)
     In Ireland, one of the continuous mounds or ridges of
     gravelly and sandy drift which extend for many miles over the
     surface of the country, deposited by streams in meltwater
     channels under glaciers. Similar ridges in Scotland are
     called kames or kams. The spelling form esker is now
     the most commonly used, and the term is applied in geology to
     similar ridges created by glaciers anywhere in the world.

     up to 100 miles long. [Written also eskar and esker.]
