The Russell Glacier is a medium-sized glacier on the north flank of Mount Rainier, Washington. Named for the geologist Israel Russell, it covers and contains 3.1 billion ft3 (88 million m3) of ice. Starting from its highest point at , the Russell Glacier flows northeast towards the Carbon Glacier and contributes ice to the larger glacier before becoming distinct below . With most of the ice located from to , the glacier only descends to , unlike the much lower extent of the Carbon Glacier. Echo Rock and Observation Rock, two minor sub-peaks of Rainier, lie northwest of this glacier. Meltwater from the glacier eventually reaches the Carbon River.
