BAY OF QUINTE SECTION 231 



Moira lake, just south of Madoc village being an expansion of the river 

 on the inner lowland. It enters the cuesta below Stoco lake (also on 

 the inner lowland) in a valley of the first type, follows this valley for 

 about 8 miles, until displaced by morainic deposits near Thomasburg, 

 whence it flows in a new channel cut in drift until it is joined by an 

 important tributary from the northeast near Plainfield. This tributary 

 in part of its course, and in all probability in all of it, occupies one of 

 the old rock valleys. The united streams continue in the course of the 

 old valley to Foxboro, where they turn south and flow with numerous 

 rapids through a new channel in a straight consequent course to the bay 

 of Quinte at Belleville. 



The eastern portion of the Trenton-Desoronto division is more com- 

 plex, and it is necessary first to refer to the most important tributary 

 stream, the Salmon river. This stream enters the limestone escarpment 

 from Beaver lake, the latter lying on the inner lowland near Tamworth. 

 The valley of the Salmon all the way across the limestone area is deep 

 and, relatively to the valleys of the other streams, narrow and very 

 steep scarped, especially on the southeast side. 



Running along the south shore of the bay from Green point opposite 

 Desoronto to Northport, and thence southwest past Demorestville and 

 Crofton and across Prince Edward county to the north of Consecon creek 

 and lake, is a well defined cuesta. At Telegraph narrows, about 4 miles 

 west of Desoronto, the bay is very shallow, and rock is exposed in 

 numerous places on either side and forms islands in the bay. Telegraph 

 narrows probably marks a local divide between waters which flowed in 

 front of the cuesta eastward to join the valley of what is now the Napanee 

 river and the Long reach, and westward in front of the cuesta along the 

 general course now indicated by the direction of its crest. This valley 

 was confluent with that of the Salmon river to the west of what is now 

 Big island. This main valley was probably joined in the vicinity of 

 what is now Wellers bay, on the west coast of Prince Edward county, by 

 the stream which carved the valley now occupied by Consecon creek 

 and lake. Several other minor valleys are also associated with the 

 Salmon river valley, but in the absence of topographic maps it has not 

 been possible to work out all the details as yet. The unsubmerged por- 

 tions of the intervalley areas of these confluent valleys form the three 

 large islands southeast of Rossmore. 



Long reach and Napanee river. — The Napanee river rises on the Archean 

 upland to the northeast of the Black River cuesta, and traverses the lime- 

 stone region in a deeply incised valley, the rock scarps of which may be 

 followed all the way across from the front of the cuesta to the bay of 

 Quinte. The scarps on both sides along the upper portions of the valley,
