Hydrothermal features at Furnas include several fields of fumaroles, hot springs, bubbling pools and mudpits, and the emission of carbon dioxide both at springs and through the soil. Fumarole fields are found on the north shore of Furnas Lake, in the river gorge of the Ribeira Quente, the Ribeira Quente village on the coast outside of the caldera, and in the upper Ribeira dos Tambores. A significant fumarole field, including the hot spring seen here, is located in the main fumarole field, Caldeiras das Furnas, in the village of Furnas.
