been carved out in times past by the normal land drainage of the 

 area in which they occur. They are mostly steep-sided, and in 

 those which still contain streams the latter are insignificant in 

 comparison with the channels which they respectively occupy as 

 to be evident misfits. 



The party travelled to Armoy by train, and then drove to 

 Glenshesk. The drive from Armoy took the members through 

 the valley between Knocklayd (1,695 f eet ) an d Croaghan (1,368 

 feet). This valley runs nearly east and west, and falls slightly in 

 the latter direction. At its upper (eastern) end it is cut off by 

 Glenshesk, running from south to north, a much deeper glen, and 

 thus under present conditions there is no possible catchment for 

 a stream of sufficient volume and power to excavate the valley. 

 In point of fact it is now almost streamless. The conductor 

 pointed out how this valley had been cut by the overflow of a 

 lake which temporarily existed in Glenshesk, and whose waters 

 were held up by the ice front of the Firth of Clyde glacier. This 

 huge glacier would appear at that time to have stood across the 

 mouth of the glen in much the same way that the great Aletsch 

 glacier of Switzerland holds up the waters of the Merjelen See. 



On reaching the neighbourhood of Glenbank House, in 

 Glenshesk, seven members of the party descended to the Shesk, 

 and, crossing it by a wooden footbridge, were soon lost to view 

 in the recesses of the moorlands. After crossing to the right 

 (eastern) bank of the river Dr. Dvverryhouse first explained the 

 features presented to the eye on looking up the Shesk towards 

 Eohilbreaga (1,077 f eet )- Then he led the way up by the 

 Owencam River to the ford, where the latter stream is joined by 

 the Greenan Water. Bending abruptly to the left, the channel of 

 the Owencam was closely followed up among the hills, where it 

 winds through a sinuous rocky gorge, until the members reached 

 the open moorland. Overflow channels of a singularly impressive 

 type were studied. These, as pointed out by the leader, had a 

 different periods discharged the surplus waters of a second ice-
