Some techniques in the study of the structural organization of glacial tills are described. The first of these employs a modified version of Harrison's method of studying mesofabrics (clasts 64-2 mm). A lightweight goniometer, suitable for expedition work, is described and some field results presented from a subglacial environment. A dry-brushing technique designed to accelerate fabric analysis and render it less selective is also described. Results of examinations of three-dimensional microfabrics of the same tills using the scanning electron microscope are also presented. The methods, used in combination, increase the diagnostic and analytical potential of till fabric analysis.
