THE FAULT AND 1M All, AT L'ANSE AU SAUVAGE ON THE FORILLON, 



GASPE 



L'Anse au Sauvage or Indian Cove lies a little more than half way 

 between Grande Greve and Cape Gaspe on the Forillon peninsula. In my 

 map of the Forillon I have shown only the limestone succession on this 

 slender, half devoured mountain ridge. The Gaspe sandstone overlying 

 these limestones does not appear in its normal attitude outside the head- 

 land of Little Gaspe which is 6 

 miles from the end of the Forillon. 

 For all the extent of the Forillon 

 this sandstone has been torn away 

 by erosion leaving the banks of 

 Grande Greve limestone sloping 

 steeply into the waters of Gaspe 

 bay. 



L'Anse au Sauvage is one of 

 the larger rock walled beaches of 

 this coast which together form an 

 array of singular scallops along the 

 water front where the pounding 

 of the sea has dislodged ami con- 

 sumed extensive joint blocks of 

 the limestones. These blocks have 

 been slightly tilted and often recemented by calcite and barite veins, 

 sometimes carrying small quantities of galena and marcasite, and it is these 

 little metalliferous veins along faces of jointing or slight displacement that 

 have given birth to the many attempts which have been made to win silver 

 and lead from these mountains. At L'Anse au Sauvage the end walls of 

 the beach are the limestones but the long back wall measuring 350 feet 

 presents a face of Gaspe sandstone faulted down into the limestones. 

 The fault lines are well marked. At the western end is a pronounced
