Mount Rainier National Park Air Quality

Visibility Monitoring Mount Rainier National Park Mount Rainier National Park is located downwind of a number of urban and industrial areas to the northwest and southwest and is not isolated from the by-products of industrialization. Manmade air pollutants are transported long distances and have been detected through air quality monitoring programs. A number of stationary and mobile sources of pollutants affecting the park include a variety of sources in the Puget Sound region as far north as Vancouver, and as far south as Portland, Oregon. Pollutants traveling across the Pacific Ocean from Asia, and including pollutants from Europe and eastern North America that circumnavigate the globe, are deposited in lakes, streams and on land within the Cascade mountain range at high elevations. National parks over 6,000 acres and national wilderness areas over 5,000 acres that were in existence before August 1977, are designated as Class I areas.

Mount Rainier National Park and some of the surrounding U.S. Forest Service wilderness areas are Class I areas. Areas designated as Class I receive the highest level of air-quality protection. Consequently, Mount Rainier National Park staff are very involved in the National Park Service's comprehensive air resources management program, designed to assess air pollution impacts and protect air quality related values. Air quality related values include scenic vistas, sensitive natural ecosystem processes, functions and components and cultural resources, The air resources management program at Mount Rainier includes monitoring, research, and regulatory interaction with local, state and federal agencies. Long-term monitoring programs include monitoring for gaseous pollutants such as ozone, visibility impairment, and atmospheric depositions. More information is available on the IMPROVE (Interagency Monitoring of Protected Visual Environments) web site.

In addition, there is an ongoing effort to determine the ecological effects of air pollutants on park resources. A digital camera has been installed at Paradise to show the effects of air pollution such as visibility impairment. The camera site is located about 23 miles from our primary air monitoring station but current levels of ozone, the visual range, and weather conditions can be viewed at The digital photos are usually updated every 15 minutes, while air quality values are revised hourly.

November's Featured Park
The North Cascades have long been known as the North American Alps. Characterized by rugged beauty, this steep mountain range is filled with jagged peaks, deep valleys, cascading waterfalls and glaciers. North Cascades National Park Service Complex contains the heart of this mountainous region in three park units which are all managed as one and include North Cascades National Park, Ross Lake and Lake Chelan National Recreation Areas.
November's Animal
Badgers are animals of open country. Their oval burrows (ten inches across and four to six inches high) are familiar features of grasslands on sandy or loamy soils of the eastern plains or shrub country in mountain parks or western valleys.
