Fata Morgana

North America's tallest mountain, Denali, was glowing in low angle afternoon light yesterday. This was taken approximately 130 miles from the base and you can see why it is the steepest vertical rise in the world, ascending from sea level to more than 20,000 feet in that relatively short distance. The mirage at the base of the mountain, known as Fata Morgana, is caused by warm air settling over the top of a colder, denser air mass, resulting in an atmospheric duct that acts as a refracting lens.

There's a bit science to start your day. As always, thank you for following along!
