The Cowlitz Glacier is on the southeast flank of Mount Rainier in the U.S. state of Washington.

[2] The body of ice covers 1.3 square miles (3.4 km2) and has a volume of 6 billion ft3 (170 million m3).

About 35,000 years ago, the combined Cowlitz and Ingraham glaciers terminated some 62 mi (100 km) from Mount Rainier.

As the Ice Age ended the glacier retreated north back to Mount Rainier.
