Grand Canyon enveloped in cloud
Stunning photographs of a once in a decade Grand Canyon cloud inversion have emerged.
The Grand Canyon National Park published the stunning pics on its Facebook page saying park rangers had waited years for the rare weather phenomenon which filled the entire canyon with cloud.
Ranger Erin Whittaker told the Daily Mail that temperature inversions happened on average once or twice a year, but never to such an extent.
Most only fill up parts of the canyon or happen on cloudy days, he said.
Friday's inversion was on a clear day and enveloped the entire canyon - an event Ranger Whittaker said happened about every 10 years.
The Facebook post accompanying the photographs said: "Much better than Black Friday! Here's what Mather Point looked like this morning with the rare inversion.
"Rangers wait for years to see it. Word spread like wildfire and most ran to the rim to photograph it. What a fantastic treat for all!"
