Hydrothermally altered rocks are exposed over a wide area in the Sulphur Springs thermal area of Qualibou volcano.  The thermal area, located in a valley SW of Terre Blanche lava dome, contains 11 hot pools, some of which occasionally produce small steam-driven fountains about 1-m high.  Sulphur Springs was the site in 1766 of the only historical eruption of Qualibou.  A small explosion deposited ash and cinders over a wide area. Photo by Lee Siebert, 1991 (Smithsonian Institution).
