Proposed mechanisms for the Cenozoic landscape evolution in southwestern North America (SWNA) include crustal isostasy, dynamic topography, or lithosphere tectonics, but their relative contributions remain controversial. Recently our study 'Coupled influence of tectonics, climate, and surface processes on landscape evolution in southwestern North America' published in Nature Communications tried to answer that.
