Standing on the edge of the Grand Prismatic Spring

While the entire geyser basin is an amazing place, the Grand Prismatic

Spring is incredible. To stand on the edge, on a windy day like this and feel

the heat and smell of sulfur wash over you is unworldly. You must go here.

Very neat image. I have actually been there. I like the blue yellow and orange in the spring. It is a very beautiful spring. I like your HDR take on it. I do notice some dust on the very left above the tree line. Overall great image.
