Happy New Year! Let's go back and take a look at the top five geologic stories for Yellowstone in 2025.
Number five: Rumors. It was a year of internet rumors, mostly related to animals fleeing the park, and none of which were true.

Just last week, Kīlauea put on another dramatic display of lava fountaining and flows within the caldera, during its 37th episode of this most recent eruption. It doesn't seem like Hawaii and Yellowstone have a lot in common, but actually, those two magmatic systems have a common cause.

The Yellowstone caldera is vast – 45 miles across by 30 miles wide. You could fit over 60 islands of Manhattan in this area. There are deep canyons, like the one on the Yellowstone River, that reveal a complex geologic history. And, forested landscapes and features remind us that this special place is ever-changing.

Picture a Yellowstone eruption. What comes to mind? It’s a huge explosion, right? Like the one that formed the caldera about 631,000 years ago. But the most common form of eruption in Yellowstone isn’t a huge explosion, it’s a lava flow.

During a USGS Hawaiian Volcano Observatory helicopter overflight on the morning of August 5, geologists observed a lava pond within the north vent of the ongoing Kīlauea summit eruption. The pond was feeding a subterranean lava tube contained within the east side of the vent cone, toward the floor of Halema‘uma‘u crater.

Grand Prismatic Spring is the largest hot spring in the US, and one of the largest in the world. The boiling lake was named for the spectacular array of colors along its rim.

There’s a lot of hot water in Yellowstone. What’s it heated by? The magma chamber beneath the surface, of course!

If you want to find a lava flow in Yellowstone, look to the trees! The vegetation is telling us more than you might think.
YVO Scientist-in-Charge Mike Poland reveals how vegetation can be used to map geology in this month's update from the Yellowstone Volcano Observatory.

The purpose of the USAID USGS Volcano Disaster Assistance Program is to make sure that volcanic eruptions don't become volcanic disasters. VDAP’s focus is to support volcano observatories through a combination of in-country or virtual support during volcanic eruptions or unrest and long-term capacity building through donations and training.

Up until the 1950s, visitors to the Old Faithful area could take a dip. Not at a geyser, but in a real swimming pool. The full story is in this month’s video update.

USGS Hawaiian Volcano Observatory geologists visited the fissure that formed on the upper Southwest Rift Zone of Kīlauea volcano early this morning, June 3, 2024. Elevated gas emissions are being carried downwind, in a southwest direction. USGS video.

During an overflight at approximately 6 a.m., USGS Hawaiian Volcano Observatory geologists observed the fissures system that opened on the upper portion of the Southwest Rift Zone early this morning. Approximately half a mile (about 1 km) in length, only the southwest portion of the system was active by daylight.

Mount St. Helens and Yellowstone are two of the most well-known volcanoes in the United States. They have some pretty obvious differences, but they have some similarities as well. So, just how similar are Mount St. Helens and Yellowstone?

A stylistic interpretation of pre eruption snowcapped Mount St Helens as seen from a blue Spirit Lake with green rolling hills.
Text changes to May 18, 1980, Eruption. There is a grey explosion of rocks and smoke coming out the top of Mt St Helens. The hills and water are grey and brown.
