This cloud was the grand finale of a big summer monsoon thunderstorm in the high country of Colorado. This cloud monster was basically hovering over the same area in the Wet Mountains for hours, slowly growing in size. And growing. Finally, just before darkness, this by now gigantic cloud started to to explode: Lightning illuminated the belly of the beast and eventually the lightning bolts were reaching out of the vapor mass and were shooting nonstop in all directions. The most intense and scariest thunderstorm I have ever witnessed. But at the same time so stunningly beautiful, that it was truly mesmerizing.
