A once-in-a-decade natural phenomenon at the Grand Canyon saw the National Park fill with fog in a spectacular treat for visitors to the world-famous attraction.
The Grand Canyon National Park posted photos of the breathtaking phenomenon on its Facebook page on Saturday and captioned the image above: "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!"
KCTV5 reports that a 'temperature inversion' was responsible for the beautiful sight.
The phenomenon happened as cold air was locked up in the Grand Canyon with warm air sitting above it.
The chilly air in the canyon cooled and clouds formed, filling it with fog.
Social media users took to Facebook to check out the amazing photos and one said: "THIS is far better than black Friday!!!"

Considered one of the most spectacular gorges in Europe, Gorges du Verdon in south-east France is around 25km long and up to 700 metres deep. It was formed by the Verdon River and one of its most distinctive features is the turquoise-green of the river. Tourists flock to the gorge to kayak, hike and climb, and the most impressive part of it is between the towns of Castellane and Moustiers-Sainte-Marie, where you can see a picturesque ravine. Don't miss the amazing rock structures of the Styx du Verdon and the scenic Sentier Martel hike.
Located in the south of Namibia, the Fish River Canyon is the second largest canyon in the world and features a gigantic ravine about 160km long and almost 55 metres deep in some places. The canyon follows Namibia's longest interior river, Fish River, into Orange River, which then flows out to the Atlantic. It is one of southern African's top spots for hiking. The trip through ancient landscapes is strenuous and takes around four days to cover the 53 miles of rocky desert terrain, pools and sulphur springs. Look out for mountain zebra, rock rabbits, baboon and elusive leopards.
Ristikallio Gorge, located in North Eastern Finland's Oulanka National Park is a famous viewpoint on the popular hiking route, the Karhunkierros Trail. The gorge is fantastic starting point for the Bear Trail Hike, where many people hope to spot the elusive brown bear, which makes the area its home. The River Aventojoki flows between the cracks of the bedrock switching from one crack to another.
As Britain's biggest gorge and 300 million years in the making, Cheddar Gorge is a must-visit UK attraction. The limestone gorge in the Mendip Hills is the site of the Cheddar show caves, where you can see Britain's oldest complete human skeleton, the 9,000-year-old Cheddar Man. The maximum depth of the gorge is 137 metres with a near-vertical cliff-face to the south. At the gorge you can learn about geological formations, prehistoric cannibalism and even embark on a crystal quest across Gough’s Cave, which was formed between 500,000 and 15,000 years ago by water dissolving the limestone rock.
Named after the herds of pronghorn antelope that roamed freely in the canyon, Antelope Canyon in Arizona is one of the most intriguing canyons in the world and boasts mysterious and haunting beauty. The famous light beams in the Upper Antelope Canyon occur most often in the summer months, while the views in the Lower Antelope Canyon are best enjoyed in the early morning. It can be a challenge photographing Antelope Canyon due to the light reflecting off the walls but its sculpture is like no other making it well worth a visit.
One of Slovenia's most popular natural features the Vintgar Gorge is home to stunning views and the delightful Sum waterfall. Located in Bled, it is over a kilometre long and a 30 to 40-minute walk, depending on how energetic you're feeling.

Take the scenic walk past St Catherine's Church and across the meadows, which offer wonderful views of the Karavanke mountain range and the Ljubljanska valley.
Todra Gorge is located on the remote eastern side of Morocco's High Atlas Mountains where the last 600 metres of the gorge narrows to a flat stony track with sheer and smooth rock walls up to 160 metres high on each side. There is a tiny glacier stream, which must have once carried more water, and the scenery is breathtaking, with local people living in the area often seen with their donkeys or herding camels and goats. Hiking and rock climbing are the most popular activities at the gorge.
Mexico's Copper Canyon is a group of canyons in the Sierra Madre. Its name derives from the greenish copper hue of the canyon walls and it spans a total length of 37,000 miles. Remarkable legends, traditions and mysteries are hidden in the mighty walls and the indigenous people of the Raramuris and Tarahumaras communities have made the canyons their home for centuries with their lives intertwined with the mountains. Top things to do include visiting the quiet village of Cerocahui, eating fresh seafood in Los Mochis and experiencing a Copper Canyon train journey.
The vast and magnificent Grand Canyon is Arizona's most distinguishable landmark and one of America's most famous attractions. The natural wonder is one you have to see to believe and stretches 277 miles from end to end, where steep, rocky walls descend more than a mile to the canyon's floor. Learn about the Grand Canyon's two distinct sides, go on a backpacking trip or gain a new perspective by rafting in the canyon. There are historic lodges and rugged campgrounds so you can sleep at the Grand Canyon too.
The island of Crete's Samaria Gorge was created by a small river running between the White Mountains and Mount Volakias, and is 16km long. The most famous part of the gorge is the stretch known as the Gates, where the sides of the gorge close in to a width of just four metres and soar up to a height of nearly 300 metres. Samaria is a refuge for the rare kri-kri or Cretan goat, which is mainly found in the park.
View the West MacDonnell Ranges, take a cool dip in the Finke River and admire the towering sandstone at Glen Helen Gorge in Australia's outback. The gorge, located 132km west of Alice Springs, is a refuge for local wildlife and is a popular overnight stop for drivers on the iconic Red Centre Way. The landscape around the gorge is spectacular and the sandstone wall is the first thing you'll see as you arrive. The ranges of Glen Helen Gorge part to make way for the Finke River, an important waterhole for fish and migrating waterbirds.

Tornados have been ripping through parts of the USA at an alarming rate during 2011. This example was captured on camera in Limestone County, Alabama, in April. A tornado is a violent, rotating column of air that it is contact with a cumulonimbus cloud and the ground. Also called twisters, they’re characterised by the condensation funnel that touches the earth, and are surrounded by clouds of dust or debris.
On 11 January, 2010, two pranksters decided to drive their car along the frozen Union Canal in Winchburgh, West Lothian, Scotland. Unfortunately for them, the thaw had already started to set in. The canal froze solid during he longest spell of freezing weather in the UK for almost 30 years.
This dust storm engulfed the desert city of Bikaner, in the western Indian state of Rajasthan on 2 April, 2010. The town was already broiling in temperatures of 39C. Dust storms happen when strong wind carries loose sand and dust away from one area and deposits it in another.
This image of the Northern lights was captured in the Takotna, Alaska checkpoint during the Iditarod Trail Sled Dog Race in March 2011. Occurring just within the Arctic and Antarctic circles, the Northern lights – or Aurora borealis, to give them their Latin name – are the light display in the sky caused by the collision of charged particles directed by the Earth's magnetic field.
This impressive rainbow resulted from a spectacular storm and was photographed in Brandon Hill Park near Clifton, Bristol, in the UK on 27 August, 2010. The rainbow seems to rise from the top of Cabot Tower - which is itself 105ft tall - showing its immense scale. Rainbows are an optical phenomenon that occur when the sun shines on to moisture droplets in the atmosphere.
This set of footprints in freezing rain was snapped in Lexington, Kentucky, USA on 16 December, 2010. Rain that falls and becomes ‘supercooled’ when surface temperatures are below freezing point can freeze on impact with anything it touches, unlike snow which remains only partially frozen. The resulting ice is known as glaze. Freezing rain is one of the deadliest weather conditions, bringing down power line and causing numerous road traffic accidents and personal injury.
This example of smog was pictured hanging over Moscow, on 7 August, 2010, and was caused by the billowing smoke from peat bog and forest fires. Smog was originally a description of the pollution resulting from factory smoke and fog in the 1900s. Today it’s more often caused when sunlight reacts with car exhaust, coal power plants or factory emissions and the compounds released from petrol, paints and solvents.
This crashing wave was caused by the approaching of the Hurricane Earl in Fajardo, Puerto Rico, in August, 2010. Earl battered some islands across the northeastern Caribbean with heavy rain and roof-ripping winds, rapidly intensifying into a major storm on a path projected to menace the United States. Hurricanes are triggered by low pressure areas forming over warm ocean waters.
In March 2011, the 'supermoon' was the closest it had been to earth for18 years lighting up the night sky from just 221,567 miles (356,577 kilometers) away. This snap was taken from Huntington Beach in Los Angeles.
Rainstorms come and go, but not usually as dramatically as this downpour which completely flooded the town of Wuzhou in southwest China on 9 June, 2010, proving that the trusty umbrella isn’t always protection enough...
Ash covered everything for thousands of miles after the eruption of Iceland's Grimsvotn volcano in May 2011 sent clouds of ash high into the air, carrying it toward the European continent on the wind, disrupting flights for the second time in less than a year.
This magnificent lightning strike hit a tower during a thunderstorm in Zurich, Switzerland on 12 August, 2010. Lightning occurs when the balance between the negative charge of storm clouds and the positive charge of the earth is redressed by a current passing between the two - with literally stunning results.
This halo around the sun was photographed on the island of Spitsbergen in the Arctic Circle on 19 April, 2011. These halos - spectacular and eerie at the same time - are caused by ice crystals in high clouds. They tend to occur during the summer months, during ‘midnight sun’ season in the Arctic and Antarctic Circles.
