The Grand Prismatic Spring is the largest hot spring in the park and the most colorful. The spring itself is an eerie blue because of the clarity and depth of the water, and there are red thermophilic bacteria growing around it along with some pinkish mineral deposits. The best view is from above (GPS from above) but the trek to the top of the mountain was above my pay grade so I took this shot standing on a bench.

Another hot spring with a cool blue tint. These things are all over the place. This one has some yellow-ish bacteria around it.
I'll leave off the shot of Old Faithful - the sky was gray that day.
