The traditional view of attrition and abrasion as the major agents producing glacial debris is considered in the light of recent work by engineering geologists and geomorphologists. The decomposition of certain rock types when affected by frost action leads to the concept of rock deterioration within the body of the glacier. It seems that differing rock types with varying responses to low temperature conditions would produce a heterogeneous mixture of particle size such as is usually termed glacial till. Observations in recent work on rock stability emphasise the importance of clay minerals and their mode of occurrence. It is considered that a detailed study of the stability of rocks forming the source region of a glacier should give considerable insight into the nature of the till produced.
