From Crow Valley

The usual route, after leaving the valley floor, is to climb towards the icefall and then travel beside it on the west until Crow névé is reached. The two obvious gullies to the true right of the icefall are the best options, but beware of avalanches after fresh snowfall. In summer, large pinnacles of ice crash down the bluffs on the true left. Beware of hidden crevasses. From the Crow névé, all three peaks of Mt Rolleston are accessible. The summit ridge may be cut off by deep crevasses late in the season. The low peak is reached easily from the northeastern reaches of the névé (the crux on this climb is the glacial ascent from the Crow valley).
