The Success Glacier is a small glacier located on the southwestern slopes of Mount Rainier in Washington. It covers 0.3 square miles (0.8 km²) and contains 500 million cubic ft (14 million m³) of ice.^[2] The glacier is bounded to the northwest by the Success Cleaver and to the east by the Kautz Cleaver.^[3] Starting from a steep rocky slope at about 11,000 feet (3,400 m), the glacier flows southward downhill. At around 9,000 feet (2,700 m), a small snowfield joins this glacier with the Pyramid Glacier to the southwest. Soon after this point, the glacier joins the adjacent Kautz Glacier at 8,600 feet (2,600 m).^[3] The joined glaciers flow until their terminus at about 6,000 ft (1,800 m). Meltwater from the glacier drains into the Nisqually River.^[2]
