I was wondering whether it were possible to ski or snowshoe into the Alexandra Valley along the river bottom. This requires a crossing of the heavily braided North Saskatchewan river, but avoids avalanche paths along the existing hiking trail.

I went there on Dec 17, 2020 and can report that both the North Saskatchewan and the Alexandra rivers are frozen over. The snow averaged about 1 m deep. Snowshoers and skiers can depart from the Sunset Pass trailhead to access the campsite at Terrace Creek (approx 10 km). It should be possible to follow the Alexandra along the river bottom to the confluence of the Castleguard River.
