Glacier ice which is stagnant, i.e. no longer moving. Typically dead ice is found buried under debris in terminal or lateral moraines after the glacier receded from them. Also the ice of flat glacier tongues may become dead during a phase of glacier recession.
Dead ice around the proglacial lake of Triftgletscher, Bernese Oberland, Switzerland. During the rapid recession of the glacier lateral moraines have been left behind. The dead ice is exposed where the debris cover has slid off.
