There are many myths about the origins of fog. I prefer one of the Inuit myths myself. A man being chased by a bear swims across the river. When the bear arrives, he demands to know how the man has forged the river.
“I drank the river,” the man replies.
Anxious to catch his quarry, the bear drinks and drinks until he bursts and a fine mist of water fills the air, creating fog.
