A type of volcano associated with these objects is called a tuya (TOO-yuh). When a nonvolcanic mountain peak pokes through one of these objects it is called a nunatak (NOON-uh-TACK). Their disappearance can cause isostatic rebound. They move via basal slip and plastic flow but when ablation exceeds accumulation, they (*) retreat, often leaving behind recessional moraines.
