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.

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.

Geysers and hot springs are some of the most dynamic geologic features on the planet. They are always changing and sometimes that change happens in places where we can see and appreciate it. This has been the case on Geyser Hill, near Old Faithful, in Yellowstone National Park.

Old Faithful, one of the icons of Yellowstone National Park and probably the most famous geyser in the world. But how faithful is it really? That's the question we're going to tackle in this June 1, 2023 update from the Yellowstone Volcano Observatory.

Could 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.
