PARALLEL ROADS OF LOCHABER. 17 
Note B (p. 102). 
(1.) At Brackletter, on the left bank of the River Spean, about a mile from its junction with the 
Lochy, an extensive terrace of gravel occurs at a height of 430 feet above the sea. 
(2.) On the right bank of the same river, and nearly opposite to Brackletter, several flats occur of 
detritus. One of these is a hill of detritus called “ Torr-an-Ess,” the top of which the Ordnance 
Survey makes 427 feet above the sea. Other flats to the N.W. from this hill, at the same level, are 
within sight of this hill. 
(3.) On the same side of the river, about 2 miles higher up, near the turnpike road, there is a 
place called “ Blazr-our,” witha shepherd’s house, showing an extensive flat, bounded by a steepish cliff, 
at a height of 430 feet. 
(4.) From this point, a good view can be obtained of the “extended moor” of Unachan, as Sir 
Tuomas D. Lauper calls it, and on running the spirit-level along its slope, to the north, several terraces, 
at exactly the above level, are detected. 
(5.) Having proceeded to those Unachan Terraces, I observed some flats on the side of the hill of 
Teandrish, both to the north and to the east of the manse occupied by the Rev. Mr Camron. 
(6.) In an old note book, I find the following entry, “‘ There is an evident terrace on this (Unachan) 
hill, running towards Fort-William and approaching within 6 miles of it. It is by barometer 391 feet 
above the sea. Discovered that this same terrace runs far eastward even beyond High Bridge, places 
ealled Raw and Torinesh (Torr-an-Ess) being on it.” * 
The altitude of this flat is no doubt 40 feet lower than that of the places previously mentioned, 
but if an estuary prevailed, the sea-bottom would be lower towards the sea than near the head. 
(7.) Near the base of the Aonach More, where limestone rock shows itself, covered with detritus, 
there are numerous “ pot-holes” in the rock, besides detrital flats. The height is about 400 feet above 
the sea, but I cannot state it more precisely. 
(8.) There are several places in the upper parts of the River Spean, above its junction with the 
River Roy, where very conspicuous terraces exist, at nearly the same height with those above mentioned 
at Brackletter and Torr-an-Ess. At the Roman Catholic Chapel I made the height 438 feet above the 
sea. Ropert CHAmsers, in his “ Sea Margins,” notices these levels, and considered them to be at the 
same level. 
(9.) In several parts of the district embraced by the foregoing observations, there are lower terraces, 
which appear horizontal. Thus at Dalnabee and Inverroy, there are extensive terraces about 349 feet 
above the sea. Near Liannachan (about 2 miles north of Corry N’Eoin) there is a terrace, occupied by 
boulders, 356 feet above the sea. 
* This terrace has a historical interest. My guide informed me that, in the year 1745, advantage was taken of it to 
form a rampart for cannon bearing on Fort- William ; and he showed to me what he called the embrasures.
