Yellowstone's Mexican mantle plume

The volcanic activity at Yellowstone National Park is impressive, with thousands of active thermal features dotting a nearly 4,000-square-kilometer caldera. Scientists have long suspected that a massive mantle plume underlies the supervolcano. Now, new imaging has provided the clearest picture yet of the heat source that drives Yellowstone’s volcanism.

USArray: Geoscientists' "Earth Telescope"

Big science often requires big tools. Particle physicists use huge particle accelerators. Astronomers need enormous telescopes to peer to the edge of the cosmos. Earth scientists, by contrast, normally probe the planet individually or in small groups using comparatively inexpensive instruments. This “small science” approach has served us well; using it, we have learned a great deal about how Earth works. But now, we have our own big science tool: USArray, a "telescope" for earth scientists to peer deep into the subsurface.

Bigfoot education and outreach

USArray has offered an unprecedented opportunity for earth scientists to explain to the public how we conduct experiments and test hypotheses, and what we aim to learn from the results.
