A fatiguing scramble, and the top of Carnanmore - 1,254 feet - is reached. As indicated by the name, this mountain has on its summit a "great carn," considerable remains of which are still to be seen. It is to be feared, however, that much of it has been erected into very matter-of-fact stone ditches, to mark the boundaries of "my Lord's" estate. The remaining portions are well worthy of examination.
The northern side seems to have been partially removed, thus exposing a large chamber of unhewn stones; part of a covering of larger slabs still remains in position, while others lie scattered about. It is probable the carn was erected to commemorate some great victory, or mark the burial place of some powerful chief, whose name and deeds are alike long forgotten.
Though the carn is itself a monument of antiquity, one at least of the stones used in its construction belongs to a more distant period still. On its upper surface, but almost defaced by long exposure, are several cuplike depression, evidently of human workmanship. Were these the only marks upon the stone they might easily have been overlooked; but, on the under side of the slab, which can fortunately be seen by a person entering the chamber above referred to, many more perfect hollows, arranged in something like order, are quite perceptible. The present position of the stone is certainly not that which it occupied when the depressions were cut, as many of those on the under side are now entirely out of reach.
