"Ever Changing" Canary Spring, Yellowstone. Taken in 1998 using a Nikon N-70 and Kodak "royal gold 25" film. It does not look like this anymore as the direction of the thermal water changed. For a few years this scene turned to white and grey. Now, the water flow has changed yet once more and the color of this terrace is coming back to what it was when this image was taken.
