|The summit of Mt. Rolliston (2275m) towers over the
headwaters of the Crow River when looking north from Avalanche Peak. From other
sides this mountain shows itself as a fine spire. If you keep quiet on the top
of Avalanche Peak then you may hear the thunder as chunks drop off the ice
cliffs of Crow Glacier. Crow River and its hut can be visited from here by
walking north for 1.5 kilometres to the third depression on the ridge. There a
stake and cairn mark a scree-run all the way to the valley floor.
