Areas in the Midwest and East have been blanketed in a haze of smoke from a series of wildfires blazing in Canadian provinces including British Columbia, Saskatchewan, Manitoba and the Northwest Territories, The Weather Network reported.
The jet stream has blown smoke from the fires south into the U.S., leading to "moderate" air quality in the state of Maryland, according to AirNow and The Washington Post.
The smoke is sitting high in the atmosphere, at an altitude at which it can't be smelled, said USA Today. But it also helped to create some spectacular sunsets from seen from Minnesota to the nation's capital.

The sun appears this way because its light has to travel through a smokier atmosphere, said The Weather Channel.
Air molecules spread blue and green waves of light, leaving only the red, yellow and orange hues in the sky through a heavier atmosphere. It's an effect that makes the sun look like it's shining down on Luke Skywalker and the Jawas.
Here are some photos people shared of the sun behind a haze of smoke throughout the U.S.:

@capitalweather I wonder whether early mammals witnessed similar skies during the K-T extinction event. pic.twitter.com/rfRDPFUO97
