Text Appearing Before Image:
322 A. P. COLEMAN THE LABRADOR ICE-SHEET the work of glacial ice on the Magdalen Islands^ in the form of sandy till with well striated stones, up to an elevation of 105 feet. Above this hills of loose basaltic blocks rise to 360 feet in places, showing no evidence that a great ice-sheet ever passed over them. The islands seem too small and low to have formed an independent glacial center, and it is probable that the thin southeastern margin of the Labrador ice-sheet inclosed them without crossing the hilltops. If so, the thickness of the sheet at this point can not have been more than about 200 feet. Whether the fee, perhaps with its edge afloat, reached Cabot Straits between Newfound- land and Cape Breton is uncertain.
Text Appearing After Image:
ScaJ4yo^ 'h^^Jj^ Figure 2.—Map of Gaspe in the Ice Age Driftless area shaded. It was thought by Chalmers that the eastern end of Prince Edward Island was unglaciated; but I have found undoubted till with well striated stones at Souris, proving that land ice covered at least the lower ground.^ The central part of the island has not furnished evidence of the action of land ice, but the west end is more or less covered with boulder-clay containing blocks derived from the mainland. There are no hills rising much above 311 feet (Wiltshire station, highest railway point on the 3 J. W. Goldthwait: Geol. Survey of Canada. Museum Bull. No. 14, 1915. A. P.
