[6] Snoqualmie National Forest was established from land in Washington NF on 1 July 1908 with 961,120 acres (3,889.52 km2).

The 1935 version of The Call of the Wild, starring Clark Gable, Loretta Young and Jack Oakie, was filmed on location in Mount Baker National Forest.

Twentieth Century Pictures believed the location was remote enough to guarantee lack of interruption from skiers and other forest visitors.

The Mount Baker–Snoqualmie National Forest covers (in descending order of forestland area) portions of Snohomish, Whatcom, Skagit, King, Pierce, and Kittitas counties.

Together with the other central Puget Sound counties, 62% (3.63 million people) of the state's population live within a 70-mile (110 km) drive of the forest.

Two tall volcanoes, Mount Baker and Glacier Peak, tower thousands of feet above the adjacent ridges.

As of 1971[update], the largest glaciers—with surface areas greater than 2.5 km2 (0.97 sq mi)—are:[9][10][11][12] The number of glaciers in the forest has decreased from 295 in 1971 to fewer than 287 in 1998.

The Skagit River System is home to one of the largest winter populations of bald eagles in the United States.
