Norris Geyser Basin is one of the hottest and most dynamic of Yellowstone’s hydrothermal areas
Many hot springs have temperatures above the boiling point (200°F) here.
The Carnegie Institute of Washington, D.C. made test wells in 1929 to determine subsurface temperatures
.One test hole was abandoned at 265 feet when the temperature reached 401 °F and the steam pressure threatened to destroy the drilling rig
. Water fluctuations and seismic activity changes featured daily. It is hard to imagine a setting more volatile than Norris.
It is part of one of the world’s largest active volcanoes. And it sits on the intersection of three major faults. One runs from the north, another one runs from the west. These two faults intersect with a ring fracture from the Yellowstone Caldera eruption 640,000 years ago.
These conditions helped to create this dynamic geyser basin. Green Dragon Spring Characterized by a unique cavern shape, the sulfur-lined Green Dragon Hot Spring is noted for its boiling green water.
Clouds of steam, however, frequently mask the spring’s beauty. On warm summer afternoons, though, the steam will frequently clear for a few minutes and allow patient visitors a glimpse inside Green Dragon Spring. Inorder to log this cache,
