Porcelain Basin

Parts of the whitish rock-sheet before you pulsate from the pressure of steam and boiling water beneath them.  A number of geysers and other features here have been born suddenly in small hydrothermal explosions.  Some features are ephemeral, their activity lasting a few hours, days, or weeks.  A few others have become relatively permanent fixtures in the scene.
