This is a photo of the Grand Prismatic Spring at Yellowstone National Park. I went there on a family trip in 2007. During the day the Grand Prismatic is full of beautiful colors. We had seen it earlier in the day but decided to visit it again at dusk before we left the park. The colors were muted but still elegant. I took this picture on a whim and didn't think it would come out at all. I was pleasantly surprised to see this on my camera.
