Photographer's Note

This is the top of Mammoth Hot Springs in Yellowstone National Park. I was there in the early morning and it was actually lightly raining when I took this. It felt like a b/w day with how much overcast there was to deal with. I looked on my LCD on my D200 and thought they looked b/w on my screen so I figured I壇 approach this one the same way.

I know the white area might look like snow but it痴 actually a pure form of travertine. What痴 happening here is that the very hot water loaded with calcium carbonate is flowing through the area and creating the travertine rock through a sedimentary process. Travertine rock is actually used as a building material and was in fact used in the Coliseum in Rome. The purer the travertine is the more white it has in its color.

In the middle of the shot that is steam rising from the spring and not fog, hence the name Mammoth Hot Springs. Taken around 10am.
