Ice rumple
A locally grounded area of ice shelf which is overridden by an ice sheet. ice rumples are distinguished by crevassing together with a rise in the surface. The criterion for distinguishing between ice rumples and an ice rise is the direction of ice movement as shown by the crevasse pattern. ice may be deflected or even halted by ice rumples, but in an ice rise, movement is independent of that of the ice shelf and, being inthe main radial, will in places oppose it. No known ice rumples rise more than 50 m above ice shelf surface level, whereas ice rises may be up to several hundred metres high.
