Norris Geyser Bassin

The Norris Geyser Basin is the hottest geyser basin in the park and is located near the northwest edge of Yellowstone Caldera near Norris Junction and on the intersection of three major faults. The Norris-Mammoth Corridor is a fault that runs from Norris north through Mammoth to the Gardiner, Montana, area. The Hebgen Lake fault runs from northwest of West Yellowstone, Montana, to Norris. This fault experienced an earthquake in 1959 that measured 7.4 on the Richter scale. Norris Geyser Basin is so hot and dynamic because these two faults intersect with the ring fracture zone that resulted from the creation of the Yellowstone Caldera of 640,000 years ago.

Le bassin de Norris Geyser est le bassin le plus chaud du parc et est situé près du bord nord-ouest de Yellowstone Caldera près de Norris Junction. Le Norris-Mammoth Corridor est une faille qui s’étend de Norris nord par Mammoth au Gardiner, Montana. La faille Hebgen lac va du nord-ouest de West Yellowstone, Montana, à Norris. Cette faille a connu un tremblement de terre en 1959 mesuré á 7,4 sur l’échelle de Richter. Norris Geyser Basin est si chaud et dynamique car les deux failles croisent l’anneau de fracture qui a engendré la création du Yellowstone Caldera d’il y a 640.000 ans.
