Grand Prismatic Sprint is amazing when you see those National Geographic aerial shots, but in person it is even more stunning. The colors are an amazing rainbow made by different bacteria living at the various temperatures out from the center of the spring. My most memorable view was this one from the hill to the south east (as I remember) that has an unofficial trail. Along the top of this painting you see the grey boardwalk that gives visitors a closer look at the spring.
I am considering whether this or some other composition would make a good larger painting.
