Clouds saturated the Grand Canyon on Wednesday, Jan. 28, creating a tranquil sight in a rare inversion.
In just 30 minutes, clouds covered the region and retreated in a westward direction, leaving the canyon in its previous state as if nothing took place.
"It was as if a blanket were slowly being pulled back to reveal the canyon," the National Park Service said.
Thick clouds rolled into the base of the canyon and swelled to reach the top of the peaks in an uncommon event that requires just the right conditions to occur.
The phenomenon was caused by a temperature inversion, or simply, a reversal of normal air temperatures, which allowed a shallow layer of cold air sit at ground level and warmer to hover above it.
Showers occurred over the Grand Canyon the previous day, sparking suitable conditions for an inversion to take place.
"Showers the day before would leave enough moisture to enhance any cooling, leading to the inversion," Anderson said.
The inversion then traps the clouds like a lid, Anderson said.
In December 2014, similar sights were visible as a dense fog overtook the canyon.
Wednesday's event marks as the third inversion that in two years for the park.
