The summit of the hill (3136 feet) showed no glaciation. Ice, 
however, had gone over the col (2600 feet) between this hill, and 
that to the west (not named in the map). 
From the 2500 feet contour line, to within almost 200 feet of 
the bottom of Glen Oban, there is one of the most tremendous 
scenes of glaciation probably to be seen in Scotland. 
The sides of the glen abound in shallow corries, with large por- 
tions scooped out in some places, and smoothed over in others. 
There are precipices at many places rounded from top to bottom, 
some of them more than 100 feet in height. Local glaciers may have 
done the work. 
Glen Oban, looking east. 
The scooped-out parts of the Glen face the north, at right angles 
to the trench of Glen Oban. 
The central parts of the Glen are nearly blocked by enormous 
masses of rock, fallen from a cliff on the north side, about 700 feet 
above. 
At the mouth of Glen Oban, looking eastward, there are fine 
examples of perched blocks. These blocks in two cases rest on 
glaciated knolls or nobs of rock, situated in the centre of the Glen, 
as shown in the foregoing rough sketch. These knolls are from 
300 to 400 feet high, and cannot be climbed, their sides being 
so steep.
