* Quaking aspen grows in groves that seem to whisper when the wind rustles their leaves. Naturalist Donald Culross Peattie described the effect of aspens in the wind: "...as they rustle they also twinkle, their lustrous upper surfaces forever catching the light like thousands of little mirrors flashed in mischievous fingers to dazzle the eyes." (1950)

* Quaking aspen wood is of relatively poor quality, but since the tree can regenerate quickly in disturbed areas, it is being harvested for wood pulp.
