The National Science Foundation has proposed a $75 million project for its next budget that would create a network of scientific instruments to analyze the continent over a range of spatial and temporal scales. The project, dubbed EarthScope, would create a downward-looking geophysical "telescope" to probe the continent from the surface to its very roots and beyond. Geophysicists seeing the subsurface in unprecedented detail would join geologists dissecting surface rocks to answer questions that neither group can answer alone, such as how and why classic geologic provinces came to be juxtaposed.
