by an examination of the depth map, that the deep water at the west 

 end of the loch runs in the direction of this flat ground. Some deep 

 borings along this flat ground might lead to interesting results. 



Loch Morar (as well as Loch Beoraid) is a glen-lake which lies in a 

 transverse valley that is to say, in a valley the direction of which 

 is independent of the geological structure of the region and crosses

irregularly the strike of the rocks. This fact very probably accounts 

 for the steep sides and the great depth to which the valley has been 

 scooped out. Should the country be depressed about 40 feet, Loch 

 Morar would be converted into a submerged valley and an arm of the 

 sea like Loch Etive. By some observers it is held that the great depth 

 of Loch Morar precludes the idea that it was scooped out by river- 

 action or by ice.
