Crepuscular Rays Create Spectacular Colorado Sunset
(CBS4) -- Crepuscular rays created a spectacular sunset in parts of Colorado on Sunday. Dramatic shafts of light radiated from the setting sun as it moved between a layer of clouds and the mountains.
Crepuscular rays form when the sun has set behind an irregularly shaped cloud or mountain, and can point either up or down through the sky.
Crepuscular rays along the Front Range are most commonly seen during the late afternoon or early evening, and are commonly associated with thunderstorms.
Clouds help scatter sunlight, creating beams of light.
