Looking southwest, Norris Porcelain Basin during very low water level on a sunny day, there are a multitude of thermals all venting stream or erupting
The Norris Geyser Basin is the hottest geyser basin in Yellowstone park and is located near the northwest edge of Yellowstone Caldera. Norris Geyser Basin is so hot and dynamic because two faults intersect with the ring fracture zone that resulted from the creation of the Yellowstone Caldera of 640,000 years ago. The Basin consists of three main areas: Porcelain Basin, Back Basin, and One Hundred Springs Plain. Unlike most of other geyser basins in the park, the waters from Norris are acidic rather than alkaline (for example, Echinus Geyser has a pH of ~). The difference in pH allows for a different class of bacterial thermophiles to live at Norris, creating different color patterns in and around the Norris Basin waters.
