Late Palaeozoic glaciated rock surfaces and associated sediments occur along the northeastern coast of Kangaroo Island. The erosional forms include glacially polished rock surfaces, striae, grooves, chatter marks, friction cracks, crescentic gouges, p‐forms, sichelwannen, miniature rock crag‐and‐tails and roches moutonnées. The distribution and orientation of these along with till fabrics indicate a general northwesterly ice flow in this part of the Troubridge Basin. The glacial erosional forms and the presence of thick lodgement till imply that the local basal ice was at pressure‐melting point during their formation. Temperate to subpolar glacial ice conditions, similar to those currently prevailing in glaciers in Spitsbergen, are inferred.
