Located in the Hercules Glades Wilderness near Branson, this air monitoring station provides data to help federal and state agencies assess regional haze. It's part of a program called Interagency Monitoring of Protected Visual Environments (IMPROVE), charged with improving visibility in national parks larger than 6,000 acres and national wilderness areas larger than 5,000 acres. 

Of the approximately 155 national parks and wilderness areas in the program, two are in Missouri: Mingo National Wildlife Refuge and Hercules Glades. El Dorado Springs in eastern Missouri is a former IMPROVE protocol site. It provided data on regional haze and visibility in an area where no Class I park or national park existed. In 2016, EPA ceased funding it and eight other protocol sites.
