presented as a three-dimensional model by researchers at the University of Utah (click to enlarge). Here are general articles, here and here, that describe this recent work performed by the Seismology and Active Tectonics Research Group that used seismic and gravimetric data to create the plume model.Amazingly, the conduit appears to be plumbed as deeply as 410 miles. The research also reveals this surprise:
"The study's of Yellowstone's plume also suggests the same "hotspot" that feeds Yellowstone volcanism also triggered the Columbia River "flood basalts" that buried parts of Oregon, Washington state and Idaho with lava starting 17 million years ago."Image credit: UUSATRG.
