Virgin River, Zion National Park

Every July the Midwest Society for Acoustic Ecology asks people on World Listening Day to pay more attention to their sonic surroundings. This year, officials at Zion National park suggested to visitors that, “Taking a moment to listen to the burbling of the Virgin River, the wind rushing through the leaves of cottonwood trees or hearing the raspy call of a raven,” can improve the outdoor experience.
