BATHYMETRICAL SURVEY OF 



Lochan Fada enters the loch on the north-east shore. The deepest part 

 of this whole basin occurs where the great mass of Slioch on the one 

 side, and the heights of the Kinlochewe forest on the other, rise steeply 

 up from the shore, and, as it were, compress the valley into its narrowest 

 limits. 



This basin has a typical " cauldron " shape, which is brought out 

 in the section on the map, the slope on both sides down to the 350- 

 feet contour-line being one of 26J; the flat portion in the middle is 

 about 300 yards broad at the deepest place. The slope up to the 1000- 

 feet contour-line is one of 24J on the north-east shore, and one of 14 

 on the south-west shore.

It should be noted that the floor of the loch rises steeply where the 

 second fault alluded to cuts it, that part of the loch lying to the south- 

 east of this fault being very shallow. This feature is also seen where 

 the same fault cuts the east end of Lochan Fada. 



In Loch Maree a large number of the streams have formed very 

 decided alluvial cones; e.g. the large one at the mouth of the Ghruididh 

 river. This feature is much more marked in Loch Maree than in the 

 majority of lochs. Other features of interest in this basin are the 

 comparatively deep soundings in Ob nam Muc and the inlet to the 

 south-east of this; and the curious hill on the bottom of the loch to 

 the south of Letterewe (300 yards from the shore), the summit of which 

 is covered by 44 feet of water.
