The Pioneer Ice Cap ( Russian ледник Пионер ) is a glacier on the Pioneer Island in the Severnaya Zemlya archipelago belonging to Russia .
The ice cap is located in the eastern part of the island, and its highest point with 385 m is also the highest peak on the island. The ice cap begins at about 50 m height and does not reach the coast. There are no outlet glaciers . The pioneer ice cap has had a negative mass balance since it was discovered in the early 1930s. By 1953 their area had decreased by 27.3 km². By 1988 it had lost another 20% of its area. The amount of their balance line ( English equilibrium line altitude; ELA ) is now m at 350th Its accumulation zone is therefore only 21 km², the ablation zone, on the other hand, 178 km². The glacier is therefore still losing massively in area and volume. A computer simulation predicts its disappearance by 2160.
