The Upper Marine Limit in the Little Whale River area, New Quebec

ABSTRACT. The height of the upper marine limit as indicated by the lower limit of perched blocks was measured by altimeter at 21 sites. Analysis of these heights shows that the upper marine limit plane is tilted up towards 232 " 2 36". A further calculation of tilt was made by the inclusio...
