Abstract

Basal-till fabrics from three alpine glaciers ranging in length from 2.5 to 7.5 km were analyzed. Fabric patterns are similar to those reported from basal tills of lowland glaciers: a single mode parallel to ice-flow direction and a preference for up-glacier dips. Eigenvalue analysis, however, showed that the preferred planes of the a axes are weaker than those reported from one Pleistocene ice sheet. Two methods of analysis indicated that there is little relation between clast orientation and clast size or shape.
