This incredible shot (larger picture here) by Sean Heavey of a supercell thunderstorm rolling across the Montana prairie is simply stunning — but was only good enough for honorable mention in the “Nature” category for the 2010 National Geographic Photography Contest.

The winner below (who also receives $10,000 and the honor of being published in worldwide editions of National Geographic magazine) was Aaron Lim Boon Teck of Singapore. He managed to capture the eruption of Indonesia’s Gunung Rinjani volcano just as the sun was rising, the moon was setting, and hikers looked on in awe. I mean, it’s got gorgeous elements, but I think supercell was robbed.
