Only few are the lucky ones who get to witness such rarest of the rare weather event where the Grand Canyon, one of the seven natural wonders of world, is covered by a sea of clouds, making the view even more spectacular. The fog, which fills the gulf from the bottom, appears to be flowing like a seaside tide.
According to the Washington Post, “This occurs when a cold layer of air is trapped at the base of the canyon and is topped by a warmer layer. On clear, calm nights, the rate of cooling near the surface increases and, if there is low level moisture present, condensation processes kick in and fog forms.”
This rare phenomena happens once in several year and the last time when the fog had engulfed the gorge was in December 03, 2013. The Grand Canyon, which is located in Arizona, US is 446 km long, around 29 km wide and have depth of over 1800 meters.
