Igneous Contact KEEWATIN An igneous complex, chiefly basic igneous rocks together with acid Fig. 58.—Overlooking Lake Temiskaming from hill south of 666, South Lorrain. Glacial and Recent Over considerable of the area there is a covering of drift, carrying the usualglacial boulders. On the summits of tbe ridges, the drift is sometimes very deep. Thereck exposures are usually found along the slopes of the hills, where the drift isthinner. On the shore of lake Temiskaming just south of the townsite, the fine-grainedgreen rocks well preserve the glacial striae. On the main shore, just opposite a smallrocky island, the strife are very striking, and are due south (magnetic). At otherpoints along the shore, there is a little variation to the east or west of south. In the cutting of the government road just east of H R 69, the clay shows astratified arrangement. Clay hills are seen along the shore of the lake, to the mouthof the Montreal river. Five miles up the river, the clay hills are very high and muchcut by deep ravines. The total distribution of the drift is not shown on th
