Abstract

Associated with striae and other evidences of glacial abrasion are certain types of rock fracture. These have been classified and described by T. C. Chamberlin (1888) in his ‘Rock-scorings of the great ice invasions’. The three principal types are chatter-marks, crescentic cracks, and crescentic gouges. All of these are so associated with glacial sculpture and striation as to indicate that they are of glacial origin. They all occur characteristically in sets, the members of each set succeeding one another in the direction of ice motion and each individual marking having its longer axis athwart the direction of ice motion.
