The collar on 907F, one of the best-known gray wolves in Yellowstone National Park, signaled "mortality" last week—indicating the matriarch of the Junction Butte pack had died of injuries suffered in a fight at age 11.

Using magnetotellurics, researchers produced a detailed picture of the magma beneath Yellowstone, offering insights into a distant future of possible volcanic activity

New research reveals why the famously steamy park, hosting over 500 hot geysers, shows no signs of blowing its top. These days, the reservoirs of magma (molten rock) that feed Yellowstone hold pretty low concentrations of this magma. They simply don't contain enough volcanic fuel to drive the heat and pressure that would stoke an eruption.
