Looking at Cascade Mountain from Banff avenue, the ridge on the right (above the old Buffalo paddock) is the SW ridge. It was first climbed in 1977 by the late Jean Pierre Cadot and René Boisselle. In early 1900, MacCarthy (first ascent of Mt Logan in Yukon) mentioned that Cascade Mt seems to offer good rock on the SW ridge. The route starts between the two obvious buttress and gains the crest of the ridge after a few rope pitches. The upper and very steep buttress is climbed via a chimney on the left side. The entire route is 5.6 or 5.7 grade III.
