It's Steamy Sunday over on Google + so I shared this photo for that as it is nice and steamy. Thought I would share it here as well. It's the Grotto Geyser in Yellowstone National Park from this July. It was happily shooting up fountains of water and lots of steam. Never saw it fully erupt but this was fairly impressive in itself. It has a slight HDR effect on it to bring out some details.
