We aim to better understand the challenging areas that are the intraplate regions using one example: the southern French Massif Central and its numerous hundreds of meters deep valleys. We apply a multidisciplinary approach there using geomorphology, geochronology, and numerical modeling. Our dating results show that the canyon incisions are part of the Plio-Quaternary evolution with incision rate of ~ 80 m Ma⁻¹. We propose then that this incision is possible due to an active regional uplift.
