Creeping mass of ice (7)

I believe the answer is:

glacier

(Other definitions for glacier that I've seen before include "Immense, slow-moving body of ice" , "Flowing ice sheet" , "Mass of ice moving down a mountain" , "Large flow of ice" , "Slow-moving flow of ice" .)

I've seen this clue in The Times.
