Short summary

This paper combines fieldwork, ground-penetrating radar (GPR) and remote sensing in the jointed and faulted grabens area of Canyonlands National Park, Utah, USA. GPR profiles show that graben floors are subject to faulting, although the surface shows no scarps. We enhance evidence for the effect of preexisting joints on the formation of dilatant faults and provide a conceptual model for graben evolution. Correlating paleosols from outcrops and GPR adds to estimates of the age of the grabens.
