An Emerald Colored Basin in Norris Geyser Basin . . .
. . . This is a smaller version of the famous Morning Glory Pool near Old Faithful, but it is in Norris Geyser Basin.
Generally the temperature of the water determines what algae can survive, and hence what color the water appears. Generally the pools like this one are around 160 F (71 C) at the hottest, and the geysers which eject superheated water are much hotter, almost up to the boiling point of water (212 F; 100C)!
Notice the colors change dramatically the farther out from the center of the pool, and the lower the water temperature becomes.
Have a great weekend Facebook, Flickr, and 500px friends!
