about two miles long, and three-quarters of a mile wide at Split 

 Rock itself (Figs. 5 and 6). This point should not be confused 

 with one southwest of St. John by the same name. 



This area is bounded on the north by a fault which has brought 

 the Triassic into contact with the Carboniferous. The dip of the

Triassic red sandstones, shales, and occasional conglomerates is in 

 general northward at angles of about 45 degrees, but the beds 

 flatten out at split rock itself. The sediments show occasional 

 cross-bedding. The conglomerates contain only occasional pebbles, 

 and these pebbles are subangular, with occasionally very angular, 

 and rarely rounded surfaces. They do not show striations or 

 sand-blasted surfaces. Fragments of siricined wood have been 

 found near Gardner's Creek, and are noted by Dawson in his 

 Acadian Geology.
