Ben-nan-Aighean, a mountain in Ardchattan parish, Argyllshire, almost wholly encircled by the Kinglass and its affluent, the Allt Hallater, and culminating at 3141 feet above the upper waters of Loch Etive, 3½ miles to the W. Though bearing a name which signifies ` the mountain of the heifers, ' it yields but indifferent pasture even on its lower acclivities, and is almost entirely bare over all its upper half. It consists chiefly of granite, and contains a few fine rock crystals.
