Mantle-driven differential uplift has been proposed to contribute to dynamic typography in the western United States. Neogene and ongoing mantle flow is postulated to be driven by upper mantle convection and to cause subtle broad-scale differential uplift that affects surface topography. This study focuses on the possible connection between mantle convection and surface topography along the Jemez lineament in New Mexico and is motivated by tomographic images from the EarthScope experiment that show this zone is underlain by low-velocity mantle that potentially could drive uplift. To test this possible connection, we constructed a longitudinal profile of the Rio San Jose …
