Description
Norris Geyser Basin is the hottest, oldest, and most dynamic of Yellowstone's thermal areas. The highest temperature yet recorded in any geothermal area in Yellowstone was measured in a scientific drill hole at Norris: 459°F just 1,087 feet below the surface! There are very few thermal features at Norris under the boiling point (199°F at this elevation).
Norris shows evidence of having had thermal features for at least 115,000 years. The features in the basin change daily, with frequent disturbances from seismic activity and water fluctuations. The vast majority of the waters at Norris are acidic, including acid geysers which are very rare. Steamboat Geyser, the tallest geyser in the world at 300–400 feet (91–122 m) and Echinus Geyser (pH 3.5 or so) are the most popular features.
The basin consists of two areas: Porcelain Basin and the Back Basin. Porcelain Basin is barren of trees and provides a sensory experience in sound, color, and smell; a 3/4-mile (1.2-km) bare ground and boardwalk trail accesses this area. Back Basin is more heavily wooded with features scattered throughout the area. A 1.5-mile (2.4-km) trail of boardwalks and bare ground encircles this part of the basin.
The area was named after Philetus W. Norris, the second superintendent of Yellowstone, who provided the first detailed information about the thermal features.
