D.H. Mooers claims that the ice margin used for Minnesota which was taken from studies done by Dyke and Prest in 1987 was incorrect. He believes that the ice dome southwest of Hudson Bay may have been smaller. A reconstruction of the Laurentide ice sheet was done again using 21,000-22,000 14C year B.P. as suggested by Mooers. The results obtained agrees with Mooers' contention that an ice dome southwest of the Hudson Bay is 600 meters shorter than what it would have been had it been reconstructed using Dyke and Prest's ice margin.
