Constructs a postglacial uplift curve for the upper part of Tanquary Fiord from radiocarbon ages of marine shells and peat. Data show the head of the fiord to be clear of glacier ice by at least 6500 yr BP. During 6500-5000 yr BP isostatic uplift was at a rate of about 3.5 m/century and subsequently about 25 cm/cent.
