Although Terrace Spring may appear to be boiling, but it’s temperature is a relatively cool 140 F (60 C). The roiling in the pol is caused by carbon dioxide bubbles. Thousands of years ago, when Yellowstone’s climate was wetter, the water of the springs had a different composition, allowing travertine to form—just like that seen today at Mammoth Hot Spring

Named for a visit in 1891 by members of the Fifth International Geological Congress, the feature in Norris Geyser Basin has behaved as a quiet pool, geyser, and roiling mud pot.

The tallest geyser in the world, with eruptions that exceed 120 meters (400 feet), Steamboat Geyser is known for experiencing years of frequent eruptions followed by years to decades of very few eruptions. The geyser has been in a more active period since 2018.

This feature, not far from Old Faithful, has never been known to truly erupt. It gets its name from adjacent Chinaman Spring, which received its name because a concessioner (who might have been of Japanese descent) in the early days of the park used that spring as a laundry.

This waterfall on Glen Creek is in the Golden Gate area of Yellowstone National Park. The high cliffs on the west side of the canyon are ash deposits from a massive volcanic eruption 2.1 million years ago, while the massif (Bunsen Peak) on the east side is a block of magma that solidified in the shallow subsurface tens of millions of years ago.

The Firehole River drops 150 feet over three tiers in this cascade, or falls, located 2.5 miles upstream of Old Faithful. The name refers to Kepler Hoyt, the 12-year-old son of Wyoming’s territorial governor, who visited Yellowstone National Park in 1881. Philetus Norris, second superintendent of Yellowstone National Park, named the cascade.

Sizzling ground, which is hot and has a small amount of water, resembles a frying pan. These features are acidic and can be found throughout Yellowstone National Park, although one of the best and most accessible examples is along the road just north of Norris Geyser Basin.

Monthly update of activity at Yellowstone Volcano, March 1, 2023
Monthly update of activity at Yellowstone Volcano, March 1, 2023Could an external event trigger a Yellowstone eruption? No, says Yellowstone Volcano Observatory’s scientist-in-charge Mike Poland, that’s not how volcanoes work. Most of the pressure that drives a volcano toward eruption comes from within, from the exsolution of gases in the magmatic system.
