The Carstairs Kames have been the subject of debate for over 150 yr. A synthesis of previous work, along with new sedimentological data, is used to reappraise this classic British esker locality. Three morphological elements are recognised: (i) large, sinuous and anastomosing ridges; (ii) large, irregular, linear mounds; and (iii) small, low and irregular mounds. The main ridge system is composed of a core of boulder gravel with sand/pebble gravel above and adjacent to the core. The large, linear mounds contain a varied facies range which include: glaciolacustrine sediments (deltaic sequences, laminites and dropstones); debris flows; and glaciofluvial channel systems. All the deposits, both in the main ridges and in the adjacent linear mounds, contain syn‐and post‐depositional subsidence structures, including normal faults, synclinal folds and growth faults. A range of potential origins for these landforms is reviewed and it is suggested that glaciofluvial sedimentation in a supraglacial environment, controlled by a topography of ice‐cored ridges, is the most appropriate depositional model. © 1997 John Wiley & Sons, Ltd.
