Word to describe small "caves"
Posted: Oct 7, 2009 6:31 pm
I am looking for a single word (or very short phrase or even an acronym) to describe all small, cave-like cavities in the earth, regardless of origin-but with an opening to the surface. Can anyone come with a word that encompasses small "caves," "karst features" (in the lingo of the NPS), vugs, enlarge joints, rock shelters, etc?
TIA,
