Mount Aylmer is part of the Palliser Range. An impressive, pyramid shaped mountain when viewed from the east, it is almost two hundred metres higher than neighbouring Mount Costigan and often has snow cover when the nearby peaks are bare. With an elevation of 3162 metres it is the highest peak north of the Bow River for a considerable distance. From the Benchlands viewpoint, a good portion of the mountain is visible because we are looking directly up the valley of the Ghost River which takes a very direct route through thirteen kilometres of front range mountains. The mountain is also very prominent from Banff Townsite but only its smoothly curved summit rises beyond the Palliser Range.
