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}.]
[1913 Webster PJC]
