Interpretive Sign - Preserving the View

Magnificent scenery and clear air combine to create some memorable views here at Black Canyon. Look ot the northwest. On a clear day you should be able to see Grand Mesa, 35 miles away, and Monument Mesa, 60 miles distant. Views like this are threatened. Even here - miles away from major cities - the haze of air pollution is sometimes apparent. Air pollution does more than just affect the view. Soils, plants, and wildlife may suffer unseen damage from dirty air. Acid rain - rainwater contaminated with airborn pollutants - can damage streams, lakes, and entire ecosystems. The full impact of this pollution may not be known for decades. What can be done? The National Park Service monitors visibility at Black Canyon of the Gunnison. Reducing the effect of air pollution on places like this will require use of modern technology, cooperation between government agencies and private industry, and - most importantly - conservation of energy by all of us. How clear is the air today? Compare the quality of visibility today with photographs taken above at Sunset View. Can you clearly see the distant detail and color? The National Park Service is monitoring visibility at Black Canyon of the Gunnison as a part of its efforts to achieve its primary mission - to conserve the scenery, the natural and historic objects and the wildlife therein, and to provide for the enjoyment of future generations.
