Norris Geyser Basin 诺里斯间歇泉盆地 20240531 (4K)

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 (237°C) just 1,087 feet (326 meters) below the surface! There are very few thermal features at Norris under the boiling point (199°F at this elevation).
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.
