Crepuscular Rays

The waning day's shrinking cumulus clouds accentuated intense crepuscular rays in the western skies of central Oklahoma. The diverging "fan" of these rays is just an illusion; they actually are parallel to each other, as are the rays' manifestations on the opposite horizon : postcrepusculars.
