South Dakota air quality has been affected this summer by wildfires in other states, particularly those to the west. According to the National Interagency Fire Center, there were sixteen active large fires burning in Montana as of Tuesday, Aug. 29. There are also eight in California, eleven in Oregon, another eleven in Washington, thirteen in Idaho, nine in Colorado, and two in Wyoming. At times, the South Dakota sun is dim even in a cloudless sky. All that smoke can cause health problems, especially for vulnerable people. SDPB's Victoria Wicks reports.
