The relation between the complex geological history of the western margin of the North
American plate and the processes in the mantle is still not fully documented and understood.
Several pre-USArray local seismic studies showed how the characteristics of key geological
features such as the Colorado Plateau and the Yellowstone Snake River Plains are linked to their
deep mantle structure. Recent body-wave models based on the deployment of the high density,
large aperture USArray have provided far more details on the mantle structure while surface-
