Depth integrated horizontal deviatoric stresses associated with GPE differences and boundary condition forces. ac Time-slice maps of contoured GPE estimates in southwestern North America. Arrows represent vertically averaged horizontal deviatoric stress field associated with GPE variations within the lithosphere. df Time-slice maps of the stress field boundary condition superimposed on paleo-elevation model of Bahadori et al.8. Red arrows represent tensional principal axes of deviatoric stress, and black arrows represent compressional principal axes of deviatoric stress tensors. gi Time-slice maps of ratio of TGPE/TBCS. Purple vectors are model dynamic velocities relative to North America. Red line in all panels represents reconstructed position of the East Pacific Rise and San Andreas Fault System. Yellow line in all panels represents reconstructed position of continental edge
