  Eschar \Es"char\ ([e^]s"k[~e]r or [e^]s"k[aum]r), n. [Ir.]
     (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.
     Eskers vary in size and extent, but can be 100 feet high and
     up to 100 miles long. [Written also {eskar} and {esker}.]
