单词	nunatak
释义	nunatak /ˈnʌnətak / noun An isolated peak of rock projecting above a surface of inland ice or snow.McCarroll & Ballantyne suggested that the ice reached an elevation of only between 750 and 850 m a.s.l. in Snowdonia, NW Wales, and that the higher summits remained above the ice surface as nunataks.... This would leave Scafell Pikes and other peaks protruding as nunataks, consistent with the observations of Lamb & Ballantyne. Remapping of several nunataks and ridge exposures reveals that the basal Neptune Group truncates a large-scale, closed syncline, developed within the Nelson Limestone. Origin Late 19th century: from Eskimo nunataq.
