of the bedding is not different from that of the Mount Joli 

 massive, but the beach interval, continued over the surface 

 of the ground as a swampy depression, is indicative of 

 their discontinuity. 



Not far landward of this cliff is an isolated boss of lime- 

 stone conglomerate which is apparently a part of the 

 same mass, though its much more massive calcareous cha- 

 racter indicates a part not there represented and possibly 

 cut off from that by a displacement. No fossils have been 

 with certainty derived from these rocks,* but their age 

 is probably Ordovician or Ordovician-Cambrian. 



The Cap-au-Canon can be passed only at a low stage 

 of the tide, and with it the rock section ends at the South 

 Beach. 



Mount Ste. Anne. — This mountain (1,200 feet, 370 m.) 

 rises just behind the village, exposing toward the sea its up- 

 per precipitous face of red conglomerates. A grassy 

 road leads up to the mountain on the north side, but 

 on nearly all other sides the mountain faces are vertical 

 fault walls. The view from the summit is fine with clear 

 weather, affording a panorama of the coast, its capes 

 and islands, from the St. Lawrence river at the north to 

 the Bay Chaleur at the south, and of the rolling wilderness 

 of the hinterland. Ste. Anne is the foremost of a mountain 

 cluster known as the Perce mountains and is the only mem- 

 ber of it that is composed of the Bonaventure conglomerate. 

 The ascent of the mountain shows limestone conglomerates 

 in the lower part and jasper conglomerates above. The 

 attitude of these beds approaches the horizontal at the 

 south, but is undulating and dips gently down toward the 

 north. The mass everywhere sheets the upturned broken 

 and eroded edges of the vertical Ordovician-Lower Devo- 

 nian cliffs, and it here reaches its northernmost limit 

 in recognizable expression. At more northern points a 

 distinction between these conglomerates and the Gaspe 

 sandstones is obscure but there are reasons to believe that 

 the upper sands and conglomerates on the south shore of 

 Gaspe bay, which have been included in the Gaspe sand- 

 stones, pass without much change of attitude into the 

 Bonaventure formation. 



* The limestone boss was formerly a place for lime burning, but the limestone for 

 this purpose was brought from Cap Blanc and the Ordovician fossils that have been 

 referred to this outcrop may have come from the more distant locality.
