Stock Photo of Mount McKinley in Alaska at sunset. A good time to take Mountain Pictures is just after sunset, as soon as the alpenglow starts. The purple color of alpenglow gives mountain pictures that special look. The native name for this mountain, from the Athabascan natives, is Denali. Translated into English means "the great one". Denlai National Park is probably one of the best spots to take mountain pictures, summer as winter.
