The Kautz Glacier is a narrow glacier on the southern flank of Mount Rainier in Washington. Named for August Kautz, who is sometimes credited for the first ascent of Mount Rainier, covers 1.8 square miles (4.7 km²) and contains 7.8 billion ft³ (221 million m³) of ice. Upper Kautz Glacier extends south from the summit ice cap to Kautz Ice Cliff at about 11,700 feet (3,600 m). Immediately west of the main ice cliff, the glacier continues down Kautz Chute which terminates in another ice cliff just above the lower Kautz Glacier at 10,800 feet (3,300 m).
