Sir,
A glacier cave is defined by speleologists as a cave formed within or at the base of a glacier (Reference HallidayHalliday, 1966). When glaciologists and others refer to such caves they often use the term “ice cave”. However, in popular and scientific usage ice caves are “… permanent caves in rock formations, in which ice forms and remains far into the summer or throughout the year” (Reference HendersonHenderson, 1933). This is now accepted practice in the field of speleology, and it would avoid confusion if the term ice cave were no longer used to refer to caves in glaciers or other bodies of ice.
