Yellowstone Brimstone Basin (Wyoming, USA)

Yellowstone National Park, Wyoming

Volcano: Yellowstone Plateau (see Yellowstone Plateau at the Smithsonian Institution website in a new tab)
Type: Soil Diffuse Emission
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.
