Throughout its geomorphological history the South Pennine valley of Longdendale has been especially prone to landsliding and some ten landslide areas have been identified. These prove on analysis to be bedding plane slides with a strong degree of translation but often exhibiting non‐circular rotational elements as well. Instability in the lower slopes has often led to cambering and valley bulging so that the slopes become deformed and slump earth flows developed at some sites. Several different types of landslide are examined in detail and by means of pollen analysis the slides are dated from the early postglacial to at least as recently as two thousand years B.P. although it has not yet been possible to decide when these slides started. The causes of sliding are identified, and comments are made upon. The location of slip surfaces–which are frequently at the base of the Grindslow Shales above a sandstone aquifer. The geomorphic processes which built up high pore‐water pressures and steep pressure gradients in the past. The effects of sliding on the development of hillslopes in the post‐glacial period.
