The geology of the Mount Logan area, Gaspé, Quebec.

The northern flank of the Gaspesian extension of the Appalachian Mountain System is dominated by a belt of hills 2 to 12 miles in width which begins some 15 miles east of Lake Matapedia and extends 65 miles northeastward to end with the Tabletop mountains. This high belt, known as the Shickshock mountains, forms a physiographic but not geological unit, its eastern end being composed of intrusive granite and serpentine bodies whereas, to the west, over some two-thirds of its length, the peaks are the dissected remnants of a great block of Lower Paleozoic metavolcanic and associated metasedimentary rocks
