Named for the missionary Marcus Whitman,[3] it covers 0.9 square miles (2.3 km2) and contains 4.4 billion ft3 (125 million m3) of ice.

[2] Starting from near the rocky spire of Little Tahoma at 10,000 feet (3,000 m), the glacier flows southeast downhill.

[4] The small Ohanapecosh Glacier lies east of the terminus.

Meltwater from the glacier drains into the Cowlitz River.
