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.

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.

What geologic hazard is most likely to occur in the Yellowstone region on human timescales? The answer might not be what you think.

What geologic hazard is most likely to occur in the Yellowstone region on human timescales?

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.

May is traditionally the start of the field season and plans are underway to strengthen monitoring networks, collect data, and conduct research to better understand volcanic activity in the Yellowstone region. Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, outlines upcoming projects in this YVO monthly video update for May 1, 2023.

Do animals prank humans? It sometimes feels that way, says Yellowstone Volcano Observatory’s scientist-in-charge Mike Poland. Mike shows some of the ways animals have “interacted” with monitoring equipment in this April 1, 2023 monthly update of activity at Yellowstone Volcano.

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.

Winter has arrived in the Yellowstone region. The deep snow and cold temperatures are harsh for animals, harsh for humans, and also harsh for volcano monitoring equipment.

Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, provides an overview of 2022 events and December activity in this monthly update for January 1, 2023. 

Just a few days ago, Mauna Loa, the tallest active volcano on the planet, started erupting for the first time in 38 years.

November is Native American Heritage Month. Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, talks about Indigenous peoples in the Yellowstone region and describes Yellowstone’s recent seismic, deformation, and geyser activity in this November 1, 2022 monthly update.

Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, describes activity at Yellowstone in this monthly update for October 1, 2022. 

The update comes to you from Artist Paintpots in Yellowstone National Park. The paintpots are acid sulfate springs, one of three different types of thermal features in Yellowstone.

This monthly video update of activity at Yellowstone Volcano comes to you from Mammoth Hot Springs, in Yellowstone National Park, where the Yellowstone Volcano Observatory consortium had its first face-to-face meeting in four years.

Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, talks about Yellowstone’s recent earthquakes, trends in ground deformation, and Steamboat Geyser activity in this video update of May 1, 2022.

Yellowstone Volcano Observatory Scientist-in-Charge Mike Poland talks about a recent earthquake swarm in Yellowstone National Park, trends in ground deformation, and water eruptions at Steamboat Geyser, in this video update of recent activity (April 1, 2022).

Happy 150th birthday to Yellowstone National Park! The Park is truly a wonderland, and a place of continuous inspiration and learning. Listen, as Yellowstone Volcano Observatory Scientist-in-Charge Mike Poland recounts some of its unique history and provides an update of recent earthquakes, ground deformation, and geyser activity.
