o m. Truro — Alt. 60 ft. (18 m.). Truro is situated 



o km. on the south bank of the westward flowing 



Salmon river which, a few miles to the westward, 

 empties into the Bay of Minas. For 6 miles 

 (9-6 km.) above Truro, the Salmon river flows 

 through a tract underlain by Triassic measures 

 consisting of red conglomerates, sandstones and 

 shales. To the westward of Truro, similar 

 Triassic strata fringe both sides of the Bay of 

 Minas and continue uninterruptedly along the 

 Cornwallis-Annapolis valley to beyond Digby 

 135 miles (217 km.) west of Truro. Along the 

 north side of the Cornwallis-Annapolis valley 

 the Triassic sediments are overlain by a thick 

 series of flows of amygdaloidal and basaltic 

 diabase. The Triassic measures are usually 

 horizontal or possess low angles of dip, but 

 locally, the measures are faulted and otherwise 

 disturbed. 



At Truro the southern boundary of the 

 Triassic with the measures of the Riversdale- 

 Union group lies }/i mile (0-4 km.) south of the 

 railway. In Victoria Park which lies just south 

 of the station, the rocks of the Union formation 

 are excellently shown in the walls of a stream 

 gorge of unusual scenic beauty. The stream 

 which is of considerable size, appears to have 

 been deflected from its course by the Pleistocene 

 glaciers and it has cut a short, rugged gorge 

 into the head of which it falls in a series of 

 cascades. The Triassic sandstones are also 

 exposed in the park, lying on the upturned 

 Union beds, but the contact is not clearly shown. 

 Leaving Truro, the Intercolonial railway 

 proceeds in an easterly direction up the flat 

 wide valley of Salmon river. On the north bank 

 of the river, visible from the railway, are cut 

 banks in red, Triassic sandstone.
