text: A broad area of grounded ice only a few tens of meters above hydrostatic equilibrium, or ice plain, was also found immediately upstream of the present‐day grounding line, which implies that only a small change in ice thickness could have a large impact on the glacier flow because large areas of ice could become easily ungrounded and reduce buttressing of upstream ice.
