The Internal Structure of a Cirque Glacier: Report on Studies of the Englacial Movements and Temperatures
Abstract This report is of a preliminary nature; detailed analyses are being carried on at the present time. The tunnel project on a small cirque glacier in the Jotunheim area of Norway, made possible observations of englacial movements in August and December of 1951 which are correlated with surfac...

Abstract This report is of a preliminary nature; detailed analyses are being carried on at the present time. The tunnel project on a small cirque glacier in the Jotunheim area of Norway, made possible observations of englacial movements in August and December of 1951 which are correlated with surface movements. Emphasis was placed on detailed three-dimensional studies. A marked divergence of flow lines was noted in both the vertical and horizontal planes. Bands previously thought to be thrust planes were found to be of sedimentary origin and not to be discrete planes of shear.
