White Chuck Glacier

White Chuck Glacier is a retreating glacier in Mount Baker-Snoqualmie National Forest that spreads across steep terrain near Glacier Peak. Meltwater has created several small lakes in front of its terminus, marking its advanced stage of withdrawal.

The glacier core shrank significantly between 1850 and 1930 before its retreat accelerated. A northern branch vanished entirely in 2001.

The glacier draws researchers studying climate shifts in the Pacific Northwest region. Visitors can observe how this scientific focus shapes what they see on the landscape.

Reaching this site requires a multi-day hike along the Foam Creek Trail, with established camping spots available throughout the White Chuck basin. Visitors should prepare for rugged high-alpine terrain and unpredictable weather conditions.

The glacier's surface has shrunk to less than one-third of its size from 30 years ago. This rapid change has left behind a landscape dotted with mountain lakes and exposed rock that mark where ice once flowed.
