The Colorado Plateau Region includes a large area in North- eastern Arizona and Southeastern Utah. Only a small part of the study area is included in the Coluntoia Plateau—a small area of volcanic deposits in Northeastern California.

Introduction  The Yellowstone Plateau volcanic field in northwestern Wyoming, a region associated with the extensive geysers and hot springs of Yellowstone National Park, is the youngest manifestation of the Yellowstone hot spot.
The track of the hot spot extends km across the northern basin‐range province ().This track of bimodal basaltic‐rhyolitic volcanism is considered the Continental Scientific Drilling Committee,A National Drilling Program to Study the Roots of Active Hydrothermai Systems Related to Young Mag- matic Intrusions: Board on Earth Sciences, National Research Council, National Academy Press, Washington, D.C., 43 ://.
