Borehole and surface outcrop data are used to construct sub‐Chalk, sub‐Upper Chalk and sub‐Tertiary contour maps for the Chiltern area. The results show a southwest‐northeast monocline, which coincides with the change of slope at the lower boundary of the morphological bench on the Chalk dipslope that Wooldridge and Linton attributed to Plio‐Pleistocene marine erosion. Younger northwest‐southeast synclines coincide with the main transverse river valleys of the Chilterns. The monoclinal flexuring casts doubt on the value of the bench as evidence for a Plio‐Pleistocene transgression.
