A ferocious electrical lightning storm illuminates the nighttime sky over the Grand Canyon in Nevada, captured by photographer Rolf Maeder.
Using clever low exposure techinques, Maeder managed to capture multiple strikes hitting the canyon under atmospheric stormy skies last month.
Rolf explains: "Sometimes an opportunity comes very unexpected. On August 30th, my friends Scott Stulberg, Holly Kehrt, both wonderful photographers, and I were driving from Sedona to the Grand Canyon to get some sunset shots.
"On the Moran Point we noticed that far away a lightning storm was building up. That was much more than we expected, so we started setting up our tripods and started to take pictures."
