James Humphrey of LGS and Jeff Unruh of LCI have published a new paper on the tectonics driving deformation near Shasta Lake, northern California, in Geology magazine. The paper describes an innovative model for the interaction of the Sierra and Oregon Coast blocks as they rotate past each other over geological time.
