Description
Summary:Broughton Island is 50 km from the eastern margin of the 6,000 km 2 Penny Ice Cap. During the early Wisconsin (> 54,000 BP) A younger glacial readvance is delimited by lateral moraines and glacio‐marine deposits 14 C dated at 24,100±850 BP; sea level was±18 m. During th last Wisconsin the glaciers terminated some distance inland from Broughton Island and sea alevel at 9,850±250BP was +5 m on Broughton Island. The head of Maktak Fiord, which presently contains a majour outlet glacier from the Penny Ice Cap, was deglaciated about 6,000 BP.
