Acclaimed photographer Camille Seaman, best known for her award-winning works depicting polar icebergs, headed inland to the prairies of the Midwest to capture a different incredible natural phenomenon: thunderstorm clouds. For the latest entry into Seaman's storm oeuvre, the artist traveled to western Nebraska, where, with the assistance of professional meteorologists, she followed the development of a massive supercell, documenting its formation over the course of several minutes. Simply stunning.
