Great Smoky Mountain Stream

On a very rare condition hike I was able to catch this shot on a stream in the Smoky Mountains. Late spring a storm was rumbling in the background. Light was dimming, but the sun was lowering in the sky. I snapped this shot right before the clouds blocked out the sun and rain began to pour. We had to use flash lights at 7pm which was super odd. But the forest was thick and the clouds dark.
