Curious goings-on at Yellowstone National Park

Surprising Activity Discovered at Yellowstone Supervolcano
Supervolcanoes can sleep for centuries or millennia before producing incredibly massive eruptions that can drop ash across an entire continent. One of the largest supervolcanoes in the world lies beneath Yellowstone National Park, which spans parts of Wyoming, Montana and Idaho.
Though the Yellowstone system is active and expected to eventually blow its top, scientists don’t think it will erupt any time soon.
Yet significant activity continues beneath the surface. And the activity has been increasing lately, scientists have discovered. In addition, the nearby Teton Range, in a total surprise, is getting shorter.
The findings, reported this month in the Journal of Geophysical Research—Solid Earth, suggest that a slow and gradual movement of a volcano over time can shape a landscape more than a violent eruption.
Interesting article -- they start looking for one thing and discover a host of interrelated activity.
