University of Utah geophysicists who created a large-scale image of the electrical conductivity of the underground plume of partly molten rock that feeds the Yellowstone supervolcano say it suggests the plume is even bigger than in earlier images made with earthquake waves.
"It’s a bigger size" in the geoelectric picture, said Smith. "We can infer there are more fluids" than shown by seismic images.

You beat to it. I was just going to say there's a new survey of Yellowstone and there's a new thread.
I can beat that feat though. I started a new religion. I know you've visited the thread. You should join, you'd be a bishop.

Almost 17 million years ago, the plume of hot and partly molten rock known as the Yellowstone hotspot first erupted near what is now the Oregon-Idaho-Nevada border. As North America drifted slowly south-west over the hotspot, there were more than 140 gargantuan caldera eruptions – the largest kind of eruption known on Earth – along a north-east trending path that is now Idaho's Snake River Plain. The hotspot finally reached Yellowstone about two million years ago, yielding three huge caldera eruptions about two million, 1.3million and 642,000 years ago. Two of the eruptions blanketed half of North America with volcanic ash, producing 2,500 times and 1,000 times more ash, respectively, than the 1980 eruption of Mount St. Helens in Washington state.

wow i wonder if the ground temps are rising all over the park.. that might mean something
Soil temperature near Vixen Geyser, Yellowstone National Park
At this site, soil temperature is monitored about 15 cm beneath the ground surface. This region of the Norris Back Basin increased markedly in temperature during the Norris Disturbance of 2003 and soil temperature at this site may be an effective indicator for basin-wide changes in groundwater flow and heat discharge.
