The Gaspé Peninsula may be regarded as the area between the Saint Lawrence River and Chaleur Bay, extending eastward from the Matapedia River to Cape Gaspé. The width, north and south, is roughly 75 miles and the length, east and west, 150 miles.
The strata represented extend from the Cambrian to the Carboniferous; for the most part, they are excessively folded and much affected by igneous activity. The peninsula is a structural arc with the convexity northward. At the east end the general strike is a little south of east and at the west end a little south of west. The land rises abruptly from sealevel and has an average altitude of about 2,000 feet. The Shickshock Mountains, with a maximum elevation of 4,350 feet in Tabletop Mountain, form an elevated belt near the north shore; a similar belt of less maximum altitude borders the south shore.
