Details for: Yellowstone
An eruption of Old Faithful, perhaps the world's best known geyser, rises above Yellowstone's Upper Geyser Basin. Old Faithful is a periodic geyser, with eruptions to heights of about 40 m at intervals of 30 to 100 minutes. Old Faithful Lodge to the right provides a rustic backdrop to the Upper Geyser Basin, which contains more geysers than are known altogether in the rest of the world. The forested ridge in the background is underlain by massive post-caldera rhyolitic lava flows of the Madison Plateau. Photo by Lee Siebert, 1968 (Smithsonian Institution).

Data from the MaGa Database
Location: Yellowstone diffuse degassing area (View Details at MaGa DB)
Description: Yellowstone supports extensive hydrothermal activity that is related to at least one large hydrothermal reservoir at depth with an estimated temperature in excess of 300°C. Land area estimates for neutral-chloride, travertine-precipitating, and acid-sulfate areas were obtained from a digital database of the 1996 Yellowstone Soil Survey at the Spatial Analysis Center, Yellowstone National Park.

Location: Yellowstone Hot Spring Basin (View Details at MaGa DB)
Description: Yellowstone supports extensive hydrothermal activity that is related to at least one large hydrothermal reservoir at depth with an estimated temperature in excess of 300°C. The type, distribution, and extent of hydrothermal activity and accompanying CO2 emissions observed across Yellowstone are primarily related to subsurface hydrothermal processes and structural control.

Location: Yellowstone Brimstone Basin (View Details at MaGa DB)
Description: Brimstone Basin is characterized by large expanses, ~1.1 km2 in total, of highly-altered Tertiary-aged andesite of the Langford formation of the Absaroka Volcanic Supergroup rocks. The altered areas are mostly devoid of vegetation and the barren surface is generally bright white in color and is recognizable from afar.The presence of sulfur and sulfur-bearing minerals is evident across the altered areas at Brimstone Basin, and there is a great deal of physical evidence of present-day degassing of H2S.
