"Purple headed mountains" is a phrase that is often used poetically to describe mountains that appear purplish in color. It signifies the majestic and beautiful appearance of mountains, especially at sunrise or sunset when the light can create a purple hue on the peaks.
Purple Sunset was created in 2001.
Sunset Crater is located in Arizona.
The duration of Purple Sunset is 1.77 hours.
The clouds turn pink and purplish at sunset because the light becomes polarized.
The times of sunrise and sunset are very dependent on the precise location that you are interested in. The link below has a sunrise/sunset calculator.
