The Mingan Islands form an island fringe for about 75 miles on the north shore of the Gulf of Saint Lawrence, almost directly opposite the west end of Anticosti. There are twenty-two islands, of which seven may be said to be small and fifteen large. In addition, there are some smaller island bodies, of which some are adjacent to the larger islands and others, as Middle Reef and Mingan Patch, are considerable distances therefrom. Mingan Islands strata also are exposed on the mainland on Point des Morts, Clearwater Point, Ammonite Point, and most, if not all, of the shore from Trilobite Bay to Pillage Bay. It also seems probable that strata of the Mingan sequence form the summit of Mount Saint Genevieve, inland from Pillage Bay.
The islands and the several headlands may be placed in an inner and an outer group. To the former belong Harbor, Montange (Romaine), . . .
