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 ; 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 Id"^ 
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.
