Shocking satellite images show how smoke from the devastating wildfires ravaging the Western United States stretches as far as Michigan, following the destruction of five million acres of land and the deaths of at least 35 people.
Imagery provided by the National Weather Service Weather Prediction Center shows smoke billowing across the West, right in to Michigan - a distance of around 2,000 miles.
'Here is a visible satellite image valid at 2pm PDT showing the vast extent of the wildfire smoke,' the agency tweeted on Saturday.
'The area in the orange contour is smoke in the mid-upper levels of the atmosphere that has reached as far east as Michigan!
'The red contour is the dense smoke near the West Coast.'

President Donald Trump, who has said relatively little about the devastating fires, is traveling to California on Monday, and will visit McClellan Park, near Sacramento.
He is scheduled to be briefed on the fires - an addition to a previously plannedWest Coast fundraising and campaign visit.
On Friday he tweeted to thank the fire fighters - his first response in over a month of blazes.
'I have approved 37 Stafford Act Declarations, including Fire Management Grants to support their brave work,' he said, referring to an act that frees up federal funds and other resources to help supplement state and local efforts.
'We are with them all the way!'
On Saturday on Saturday night, Trump dismissed the wildfires by blaming them on California's Democratic leadership.
'It is about forest management,' he said at a rally in Nevada.
Eric Garcetti, mayor of Los Angeles, said Trump's remarks were an insult.
'Anybody that lives in California is insulted by that,' he said. 'Talk to a firefighter if you think that climate change isn't real.
'We need real action. We need to reduce the carbon emissions that we have. And we need to make sure we can manage this water. This isn't about forest management or raking.'
