Exploring thermal areas in Yellowstone's remote southwest corner

There are over 10,000 thermal features scattered throughout Yellowstone National Park, and many are in remote locations. Attempting to make a more complete record of water and gas chemisty of all the park's features, scientists from the USGS and the National Park Service travelled to the southwest corner of the park to study remote thermal areas around Boundary Creek and the Bechler River.

Yellowstone Lake Shakes

It has been well documented that the interaction of ocean waves and the seabed causes seismic shaking that is recorded by seismometers around the world. This seismic energy is referred to the earth's "microseism". Research by University of Utah Seismologists has shown that these microseisms also exist at Yellowstone Lake.

Hydrothermal Research in Yellowstone—the lasting legacy of Donald E. White

One of the most distinguished researchers and staunchest supporters of Yellowstone was Don White (1914-2002) of the U.S. Geological Survey (USGS). Don had a significant impact on hydrothermal research in Yellowstone, and his testimony before Congress, together with former park superintendent John Townsley, gave Yellowstone its protection under the Geothermal Steam Act's amendments in 1970.

Craters of the Moon: Idaho's last (and next?) volcanic eruption

Idaho is home to several young volcanoes, including the Craters of the Moon, Wapi, Kings Bowl, North and South Robbers, Cerro Grande, Hells Half Acre, and Shoshone lava fields. Craters of the Moon is one of the youngest volcanic areas in Idaho and may be the most likely in the state to erupt again.

A closer look at the 2017 Maple Creek earthquake swarm

In June of 2017, an earthquake swarm began beneath the western edge of Yellowstone National Park, just east of Hebgen Lake. This swarm proved to be one of the more persistent swarms observed in Yellowstone, with the main episode lasting more than 3 months and producing thousands of recorded earthquakes.
