Smoke from wildfires burning in Canada has drifted south into Colorado, resulting in dense smoke throughout the eastern half of the state. 

More than one million acres have already burned in Canada with almost 30,000 people forced to evacuate. There are 223 active fires in Canada. Alberta has been hit the hardest with 94 active wildfires currently burning. 

In addition to Colorado, air quality alerts are also in place for parts of Nebraska and Montana.
