Bark: The bark is gray and breaks into rectangular plates on large trees.

Where it grows: Western White Pine grows throughout the Cascades and in the Coast Range at elevations of 3000 to 5000 feet in Oregon and down to sea level in northwest Washington. Elsewhere, it grows in northeast Oregon and northern Idaho. It is the state tree of Idaho. It also grows in the Siskiyous and the Sierras, and grows down to sea level in northwest Washington.
