The Pyramid Glacier is actually a scattering of glaciers and snowfields located on the south-southwestern flank of Mount Rainier in Washington. It covers 0.2sqmi and contains 400 million ft3 (11 million m3) of ice.[2] The glaciers lie at an elevation ranging from about 7000feet to 9000-2NaN-2.[3] The Success Divide separates this glacier from the South Tahoma Glacier to the west. Both the Success Glacier and lower end of the Kautz Glacier border this glacier on the eastern side.[3] Meltwater from the glacier drains into the Nisqually River.[2]
In a June 2023 report from the National Park Service, the glacier had lost 34% of its volume between 2015 and 2021.[4] Based on 2022 satellite imagery, glaciologist Mauri Pelto declared Pyramid Glacier dead.
