Abstract

Foxe Basin, a relatively shallow sea, is bounded on the N. and E. by Baffin Island, on the W. by Melville Peninsula, and opens on the S. into Hudson Bay. A study of air photographs in conjuction with a geological survey disclosed many well-defined features such as glacial flutings, drumlinoid ridges, crag and tail structures, and eskers. Raised beaches were also seen to be extremely common. N. and W. of Fury and Hecia Strait the latest movements was from the NE.; S. of the strait the trends are E.-W.. Patterns in the vicinity of Steensby Inlet indicate that it channeled the ice; patterns E. of the inlet are NE.-trending, wheras those to the W. are NW.-trending. Raised beaches were found as high as 600ft. above present sea level and marine shells at 430 ft.. The rate of emergence of Igloolik Island, based on a radiocarbon date of 1750 B.C. +/- 300 years obtained by J. Meldgaard, a Danish archeologist, on material from a 51-m. beach, is about 4.5 ft. per century. This rate cannot be applied to all parts of the district. (incl., 5 illus., 2 maps)
