Air Quality

Over the last 30 years air quality has improved significantly in national parks and across the U.S. This is great news because parks need clean air. It is essential for the health of our visitors and employees, clean clear views of park scenery, and a healthy natural environment. But we also know that almost all national parks are still affected by air pollution. One way you can keep up with the changing air quality at Nez Perce National Historical Park is by checking our air quality monitoring of the outdoor conditions, as well as inside the Nez Perce National Historical Park Visitor Center.
