Winter Use Adaptive Management Program: Air Quality and Soundscape

Background and Area of Focus

The Soundscape and Air Quality Working Group will make recommendations to the NPS on the design of an updated monitoring strategy that measures and evaluates the impacts of oversnow vehicle use on the park's natural soundscape and on the park's air quality to ensure a cleaner and quieter park, and compliance with the new winter use sound and air emissions requirements.

Even though the animals of Yellowstone seem tame they are still wild. Feeding the animals is not permitted in any way, and all visitors must keep 100 yards away from wolves and bears, and 25 yards from other animals.
