At 15 rods east of Oak portage, on the Canadian side of Saganaga lake, a light-colored, feldspathic rock with quartzes, perhaps fragmental,butitcan hardly be distinguished from a massive crystalline granite. It lacks, however, the dark elements of granite, and is not fresh and sharp. It shows pyrites and Fig. 2. Wave Marks in Recomposed Granite near Oak Portage, Saganaga Lake. At a point about 20 rods east of Oak portage, on the Can- adian side of Saganaga lake, is a curiously marked surface of this supposed "granite," a structure which is quite unlike any.
