This is the Opal Geyser Pool located in the Norris Geyser Basin. The Opal is my favorite volcanic feature in the whole park! This picture does not begin to show how beautiful the color is, or how clear the water is.
This is part of the geyser basin between Norris and the Old Faithful areas. The volcanic core just under the surface heats the water and it bubbles up here through pools, geysers and this "waterfall" looking geyser that then empties into the river here.
The mountains in the distance were very beautiful too.
The Mammoth Hot Springs area is in the Northern most part of the park. We saw some amazing volcanic formations here too. The Hotel and "town" part of Mammoth Hot Springs is the original headquarters of the park when the army was stationed here and ran the park. This is still the headquarters and the area of a "village" were most of the park rangers and employees live.
