Actually, it's a morning light. But it works the same way. In the eastern Sierras the opposing mountains are much lower therefore the light has to travel through more of the atmosphere to hit the east facing mountains. You end up with much richer colors.
Thanks for visiting Ejnar. I have always admired all your photos.
"Got tight last night on absinthe and did knife tricks. Great success shooting the knife into the piano. The woodworms are so bad and eat hell out of all furniture that you can always claim the woodworms did it."
