Location

Nash Ridge trends in a northwest-southeast direction. The Priestly Glacier flows past the northeast side of the ridge, and the O'Kane Glacier flows down the southwest side. They join at the southern tip of the ridge. Features of the ridge, from north to south, include Mount Meister, Mount Borgstrom and Lowry Bluff. Nearby features include Eskimo Point, to the west, and Mount New Zealand and Timber Peak to the northwest.
