Geothermal Features
The geothermal features that are scattered around the valley are not as impressive as those of the large geyser basins, but in many case they were the first to be discovered and described by the early explorers. They include Mud Volcano, Mud Geyser, Sulphur Caldron, and Black Dragon Caldron at the southern end of the valley and Sulphur Spring in the Crater Hills group further north and west of the river.

Famous quotes containing the word features:
“The features of our face are hardly more than gestures which force of habit made permanent. Nature, like the destruction of Pompeii, like the metamorphosis of a nymph into a tree, has arrested us in an accustomed movement.”
—Marcel Proust (1871–1922)
