Along the winding canyon from the northwest rushes the Bow River, sliding in noisy turmoil, with ample spray and silvery foam, down a series of cascades, making a most beautiful cataract, then turning sharply at a right angle to the northeast to go around the end of a mountain. The bright green waters in full volume swiftly glide around the bend and away through the narrow gap formed between two towering cliffs into a deep gorge several miles long. The smaller, but even more swiftly-darting Spray River, dashes along rapids and joins the Bow just at the bend. Such is the scene giving the central point of beauty within this grand amphitheatre of high mountains, overlooked from an elevated plateau above the waterfall, where the landscape is finest. The Rocky Mountains Park includes about two hundred and sixty square miles of streams, lakes and enclosing mountains, improved by many miles of good roads and bridle-paths to develop its beauties. The original attraction was the Banff warm sulphur springs, appearing along the side and base of Sulphur Mountain, rising on the southern bank of Bow River above the waterfall. The temperature of the waters changes little from 90°, and they are extensively used for bathing, being recommended for rheumatic troubles. One spring of copious flow is a pool within a capacious dome-shaped cavern, hollowed out of a mound of calcareous tufa. This is the crater of an extinct geyser, the orifice at the top, which had been its vent, being availed of for light and ventilation. High up among the mountains to the eastward is the Devil's Lake, a beautiful crescent-shaped sheet of water much like a river, eleven miles long, and enclosed by towering peaks. BANFF TO VANCOUVER.
