    Alaska Range hidden behind clouds

    Science Summary (2011) - Denali’s air quality is usually among the best in the country, as measured by an air quality monitoring program dating back to 1980. This exceptional record shouldn’t be too surprising, considering the park’s remote location in interior Alaska, far from large-scale industrial activities and densely populated urban areas.

    Air quality monitoring in Denali has been ongoing for over three decades. With global pollution projected to increase over time, Denali’s clean air is dependent upon international as well as national efforts to limit emission increases. As a prominent wilderness tourist destination, the park may help inspire global citizens to protect clean air partly because it is an integral part of Denali’s intact ecosystem.
