Here is another image from my foggy visit to Great Falls National Park, Virginia. While I got grand scenic type shots that I liked (as in my previous post), the diffused light provided by an overcast sky was especially excellent for close up images. The rocks surrounding the Potomac River near Great Falls are incredibly unique. They have been smoothed by the constant rushing of water over it's surface. Additionally, there are many potholes and puddles of various sizes caused by loose, swirling rocks in rapids. This image shows a bit of both of those characteristics.
