This photo, taken by Wolfgang Hinz in Lukla, Nepal, shows these stunning crepuscular rays or sun rays [wiki]. (Jacob's ladder, or rays of light shining through holes in low clouds, are a form of crepuscular rays.) From the website:
This gorgeous photo showing pre dawn crepuscular rays was taken from Lukla, Nepal in November of 2000. As the Sun rises (or sets), rays of light interspersed with darker bands (shadows) can on occasion be seen in the direction of the Sun. Rarely are they as spectacular as these. The shadows result from clouds below the horizon but can also be caused by mountain peaks, as is the case here. Crepuscular rays seem to converge toward the horizon, but in actuality, they're parallel.
