Anti-crepuscular rays


    Surely crepuscular rays from an already set sun?  But look at their milky colour and the cattle grazing in the sunlit landscape. These are extraordinarily bright anticrepuscular rays converging downwards away from the sun to the antisolar point beneath the eastern horizon. 
The sun was shining low in the west when John Britton caught this scene from a moving car near Boulder, Colorado late afternoon October 11, 2001.
