The preferred orientation of the long axes of the stones in apparently homogeneous till varies considerably in depths of not more than 60 cm; there is no consistency in the rate and degree of variation with depth. Lateral variations in long-axis orientation over similar distances are small in comparison. Measurement of 50 stones produces a result very comparable to that obtained from measurement of 100 stones. No over-all pattern exists in the plunge of the long axis of the stones, even where similar orientation is found, and thus plunge is of no value in determining the direction of ice movement.
